Anthropic Said to Postpone IPO to Just Before Midterms | PYMNTS.com
The artificial intelligence company had been expected to release its IPO prospectus as soon as this week, Reuters reported Friday (Sept. 4), citing sources familiar with the matter. That move, a critical step that would set off the closing stages of the listing, is now not expected until late September, the sources said. Anthropic is expected to start marketing the IPO in mid-October at the earliest, completing the listing days ahead of the U.S. midterm elections, the sources told Reuters. PYMNTS has contacted Anthropic for comment but has not yet gotten a reply. The company declined to comment when reached by Reuters. As Reuters noted, companies often alter their IPO calendars as they deal with market conditions and regulatory oversight, so this change is not unusual. The report added that this shift delays what some investors have claimed could be one of the largest IPOs ever attempted at $2 trillion, and a key test of the market's appetite for AI. Anthropic hopes to finalize a $15 billion revolving credit facility as part of its IPO process. According to one of Reuters' sources, the company from there will meet with analysts, including those from banks taking part in the financing. While companies usually wait a few weeks to make their IPO prospectus public after analysts meetings, this source said Anthropic is expected to have a shorter window as analysts are already well familiar with the startup. The company's IPO could come alongside other potential AI listings, including that of OpenAI. SpaceX, which listed earlier this year at a $1.77 trillion valuation. In other AI news, last week saw a report that while adoption of the technology is spreading, the money is accumulating among just a handful of companies. New Ramp data shows that the top 1% of customers make up 80% of the enterprise revenue for both Anthropic and OpenAI. That's a concentration that has remained in place even as more companies begin paying for generative AI, Ramp lead economist Ara Kharazian said on X. "This is a level of concentration risk unseen in any other software category we track," Kharazian wrote on LinkedIn. "At Anthropic, that concentration has a name attached to it," PYMNTS wrote. "Coding tools Cursor and GitHub Copilot alone drove roughly $1.2 billion of the company's $5 billion revenue milestone last year, close to a quarter of total revenue from just two customers."

Anthropic Has Committed More Than $100 Billion to AWS, and Its Prospectus Could Reveal More Details About This Contract
Anthropic, the company behind the Claude artificial intelligence (AI) models, plans to publish its initial public offering (IPO) prospectus after Monday's Labor Day holiday, The Information reported late last month. A listing may follow as soon as late September or in October. Amazon (AMZN -0.15%) shareholders have a more specific reason than most to open the document when it lands. On April 20, Anthropic committed to spend "more than $100 billion over the next ten years" with Amazon Web Services (AWS), Amazon's cloud computing segment. That promise is equal to about a fifth of AWS's backlog of contracted work, which reached about $496 billion in June. In other words, Amazon has already told investors how much one of its biggest cloud customers intends to spend. What no Amazon filing can show is whether the customer's own finances support it. That's what the prospectus is for. The contract is already in Amazon's filings April's agreement covers up to 5 gigawatts of capacity on Amazon's own silicon -- Graviton processors and Trainium2 through Trainium4 AI chips, with an option on future generations. Amazon's filings show what a deal that size does to the backlog. AWS's backlog (commitments in customer contracts with original terms longer than one year that haven't yet been recognized as revenue) had grown to about $496 billion by June 30. That was up from about $364 billion in March, and from $195 billion in the middle of 2025 -- growth of 154% year over year, including a $132 billion jump in a single quarter. And the Anthropic deal wasn't alone. The filing also discloses a $100 billion, eight-year expansion of AWS's existing $38 billion commitment from OpenAI, announced a quarter earlier. Not only is AWS's contracted future far bigger than it was a year ago, but more of it also sits years away from becoming revenue. The weighted-average remaining life of the segment's long-term contracts stretched from 4.0 years to 6.4 years over those 12 months. One half of the deal is easy to check Of course, a backlog is signed work, not guaranteed revenue. Amazon says the amount and timing of what it recognizes "will be driven by customer usage and our performance in accordance with contractual obligations." Amazon's half of that sentence looks strong. In the second quarter of 2026, AWS's revenue rose 37% year over year, to $42.2 billion -- the segment's fastest growth in 18 quarters and a $169 billion annualized pace. Segment operating income rose about 63% year over year to $16.6 billion. And the AI business inside AWS passed a $25 billion annualized revenue pace of its own, growing triple-digit percentages. The customer's half is the part I can't verify yet. Anthropic is private, and its reported growth is extraordinary. In April, the company said its annualized revenue pace had passed $30 billion, more than triple its level entering the year. And by mid-August, CNBC reported, Anthropic was telling investors the pace had reached $65 billion by the end of July. Spread evenly, the commitment works out to more than $10 billion a year, or about 6% of AWS's current annual revenue pace. That's arguably affordable if Anthropic's growth holds, and heavy if it doesn't. And Amazon isn't just supplying the capacity. Its latest quarterly filing shows the company has put another $10 billion into Anthropic this year, with up to $15 billion more available under a financing arrangement tied to compute-delivery milestones. That means Amazon's interest in Anthropic's financial health goes beyond the contract itself. What does a prospectus settle? Nearly everything the market knows about Anthropic's finances today is reported, not filed. The company's only filing on record is the confidential draft it submitted to the Securities and Exchange Commission in June. Its expected market value is a projection. People familiar with the matter told CNBC last month that the company could go public at a valuation of about $2 trillion, about double its private-market value. Its revenue pace is self-reported, and no audited numbers are public. A prospectus replaces the estimates with audited financial statements: actual revenue, actual profit or losses, and actual cash. Even more useful for Amazon shareholders, it should carry Anthropic's own accounting of its purchase commitments, the other side of the agreements that swelled AWS's backlog. At about $259 as of this writing, Amazon's stock trades at a forward price-to-earnings ratio of about 24. For a company whose cloud segment just accelerated to 37% growth, I think that's a reasonable price. But AWS has now disclosed more than $200 billion of multi-year commitments from just two private AI companies, and until those companies file, investors can only judge them by reported figures. Ultimately, Anthropic's prospectus is the first chance to check one of them. I'll be reading it closely.
Authors push back as publishers and agents seek share of Anthropic settlement
Some authors hoping to receive their share of Anthropic's $1.5 billion copyright settlement said they received surprising emails this week -- emails informing them that someone else was making a claim on their payments. Anthropic settled a copyright class action suit last year, after a judge ruled that training AI models on copyrighted material is legal under fair use doctrine, but pirating that material was not. The deal received final approval in July, allowing the payments to move forward. Under the terms of the settlement, the authors of nearly 500,000 titles will be paid $3,000 for each pirated work. If the book is still in-print with a traditional publisher, the money will be split 50-50 between author and publisher. If the book was self-published, or if the publisher reverted the rights by allowing the book to go out-of-print, then the author should get the entire payment. But writers have been posting on social media that publishers seem to be claiming more than their fair share of some payments. For example, mystery and thriller author April Henry asked, "WTF is HarperCollins playing at? They claimed one of my books on the Anthropic Settlement that reverted back at least 17 years ago AND on the same day I got a credit alert saying they had been added as my employer! (which they never were)." At the popular blog Writers Beware, Victoria Strauss wrote that she's been receiving author complaints that fall into two broad categories: one where publishers are seeking payment for works that they no longer have a legitimate claim on (because the rights have reverted), and another where publishers are seeking a full 100% payment when they're only entitled to 50%. In both cases, Strauss said she's "reluctant to attribute to malice what can be plausibly explained by poor recordkeeping" -- and she noted that some publishers have already said this is a mistake that they've asked Anthropic to fix. Similarly, Authors Guild CEO Mary Rasenberger told The New York Times that she doesn't see this as "a grab by the publishers" and that she doesn't believe publishers are "specifically trying to screw any author over." Instead, she argued that this is the predictable result of bad record-keeping and a confusing settlement process. Strauss also acknowledged that any complaints she's seen are just "a peek through a small crack in a massive wall." "But the unusually large number of reports I've received over the last two days, as well as the fact that authors are reporting the exact same errors over and over, suggest to me that these aren't the kind of routine glitches you might expect from such a large operation, but something much more wide[s]pread and systemic," she wrote. And publishers aren't the only ones seeking a cut of the payments. Strauss said she's gotten complaints that a number of literary agencies are also making claims, which she said is surprising since "agents are not rightsholders in the books that they sell." Author Courtney Milan (the pen name of former law clerk and law professor Heidi Bond) was more blunt in a post on Bluesky, writing, "Apparently some agents are trying to claim percentages on the Anthropic settlement, and I do not REMOTELY think they should do this, what the fuck, stop that shit!" Milan and the Authors Guild also shared more details about how authors can dispute their payment allocations. (One tricky issue: When the rights to a specific book reverted. In order for an author to make a 100% claim on a book, the rights reversion needs to have happened before August 10, 2022, which is the "download date" in the settlement.)
Potential Anthropic IPO investors seek detailed revenue metrics ahead of blockbuster listing
The AI company's revenue grew more than sevenfold in roughly seven months, and prospective backers want to know exactly how that number is being counted. Anthropic is sprinting toward what could become the largest AI IPO in history, and the investors lining up to participate have one persistent request: show us the receipts. The Claude maker's annualized revenue run rate ballooned from roughly $9B at the end of 2025 to over $65B by the end of July 2026. The numbers behind the frenzy Anthropic's preliminary Q2 2026 revenue clocked in at $11.5B, up from $4.73B in Q1 2026. For context, Q2 2025 revenue was $787M. So the company roughly 15x'd its quarterly top line in a single year. That growth has also pushed the company into unfamiliar territory: profitability. Anthropic posted its first quarterly operating profit of approximately $559M in Q2 2026. The company's most recent private round, a record $65B Series H completed in late May 2026, valued Anthropic at $965B post-money. Some prospective IPO investors are now projecting a public market valuation north of $2 trillion. Internal revenue projections for 2028 sit in the $190B to $200B range, according to figures being shared with potential backers. The accounting question investors keep asking Revenue growth this steep invites a specific kind of scrutiny, and prospective IPO investors are zeroing in on one issue in particular: how Anthropic accounts for revenue generated through cloud reseller partnerships. The distinction matters more than it might sound. When Anthropic sells its models through a partner like Amazon Web Services or Google Cloud, the question is whether the company books the full amount customers pay (gross revenue) or only its share after the cloud provider takes a cut (net revenue). Enterprise customers already account for roughly 80% of Anthropic's revenue. Over 1,000 businesses were spending at least $1M annually on Anthropic's products as of April 2026. Many of those customers access Claude through AWS Bedrock or Google Cloud's Vertex AI, which means the gross-versus-net question touches a significant portion of total revenue. The path to public markets Anthropic confidentially submitted its draft S-1 registration statement to the SEC in June 2026. The company is working with Goldman Sachs, Morgan Stanley, and JPMorgan as underwriters. The public filing of the S-1 is anticipated in late September 2026, with a roadshow potentially kicking off in mid-October. The company has raised between $118B and $130B in private capital across its funding history. Amazon holds approximately 21% of the company, while Alphabet owns around 15%. For Amazon in particular, the math is striking. A 21% stake in a company valued at $2 trillion would be worth roughly $420B. What this means for the AI sector Anthropic's IPO will function as a pricing signal for the entire AI industry. If the company achieves a $2 trillion valuation, it effectively sets a new ceiling for what public markets are willing to pay for frontier AI capabilities. There's a risk dimension worth watching, too. Revenue that grows from $787M to $11.5B in a year is extraordinary, but it also means the company has very little historical baseline for predicting churn, seasonality, or customer concentration risk. Investors projecting $190B to $200B in 2028 revenue are essentially betting that a trend line drawn from fewer than four quarters of meaningful data will extend smoothly for another six quarters. The first operational profit is encouraging, but $559M on $11.5B in quarterly revenue implies thin margins relative to pure software businesses. Capital expenditure on compute infrastructure, talent costs for top-tier AI researchers, and ongoing model training expenses all weigh on the bottom line.
Salesforce Stock Has Surged as AI and Anthropic Bets Pay Off, But Technical Risks Remain - Microsoft (NAS
Salesforce (NYSE:CRM) stock has staged a strong comeback in the past few months, moving from the year-to-date low of $144 to $260. This rally accelerated after the software giant published strong financial results and as its Anthropic investments pays off in a big way. Salesforce Stock Jumped After its Earnings Beat CRM stock jumped after the company published its strong financial results, which showed that its revenue continued growing. Its current remaining performance obligation (cRPO) jumped by 14% to $33.5 billion in the second quarter, while its revenue soared by 11% to $11.3 billion. Informatica, which it acquired last year, contributed $440 million to its revenue. Most importantly, there are signs that Salesforce's approach to artificial intelligence is starting to pay off. Agentforce and Data 360 businesses generated an annual recurring revenue of nearly $3.9 billion. It had 7 billion Agentic Work Units, which were delivered across its products like Agentforce and Slack. The management boosted its forward guidance, a sign that it expects its business to do well. It now expects that its revenue will be between $46.1 billion and $46.4 billion, representing a 12% increase from what it made last year. Salesforce and other software companies have been under intense pressure in the past few months as concerns about SaaSPocalypse remained. This is the view that software companies will be disrupted by artificial intelligence tools. Markets Oracle Stock Showing Bottoming Signs as Earnings Loom 3 min read There are signs that Oracle stock is forming bottoming signs as the first quarter earnings nears on September 10 this year. Read article Anthropic IPO to Boost Salesforce Another catalyst boosting Salesforce is its investment in Anthropic, which is reportedly planning to go public at a valuation of up to $2 trillion. Salesforce first invested in Anthropic's 2023 Series C round and has since participated in every subsequent funding round. Its stake is now estimated at $5 billion, and if Anthropic reaches that $2 trillion valuation, the position would be worth substantially more. Trending Salesforce is one of the many companies that will benefit from Anthropic's IPO. Some of the other top ones are Amazon (NASDAQ:AMZN), Microsoft (NASDAQ:MSFT), and Nvidia (NASDAQ:NVDA). These events explains why analysts have boosted their CRM stock forecast. Morgan Stanley (NYSE:MS) hiked its target to $315, while Needham, BTIG, Cantor Fitzgerald, and Deutsche Bank have all boosted their targets. Technicals Points to a CRM Stock Pullback While Salesforce has some notable catalysts, technicals suggest that the stock may experience a pullback in the near term. It has already hit the crucial resistance level of $267, which aligned with the highest swing in December last year. The stock has already formed a shooting star candlestick pattern, which is made up of a small upper shadow and a body. This pattern often leads to a retreat. It has also formed a fair value gap on August 27 that it may attempt to fill. More gains will be confirmed if it moves substantially above the resistance at $267.

Anthropic settlement: who gets the $3,000 per book?
Anthropic is paying $1.5bn to the authors whose books it pirated. As the money lands, some of it is going to their publishers instead. The Anthropic settlement has run into contracts written long before AI training existed, and nobody is sure who owned what in 2021. Anthropic agreed to pay $1.5bn to the authors whose books it pirated. The money is now being counted out. Some of those authors are discovering that a share of it goes to their own publishers. The New York Times reported on Friday that authors and publishers have filed competing claims over the same titles. The settlement administrator has begun telling both sides they disagree. The class action covers more than 482,000 books. It pays up to $3,000 for each one a judge found Anthropic had downloaded illegally and stored while building Claude. A judge in the Northern District of California approved it in July. At the top rate, the full list of titles comes to roughly $1.45bn. Authors filed the case in 2024. The default split is 50/50, and not everyone gets it Authors do not keep the whole $3,000. They split it with the publishers they granted rights to, and with any co-authors. Publishers were always in line for a payout. A class-action council set the percentages. It took input from the Authors Guild, which says it has more than 18,000 members, and from publishers. Nobody negotiated them title by title. Textbook authors come off worst. Their contracts hand them as little as 10 to 15% of the total, according to Mary Rasenberger, the guild's chief executive. "It's the textbooks where there are a lot of unhappy authors right now," Rasenberger said. She does not read it as opportunism. "I don't see this as a grab by the publishers," she said. Her concern is record-keeping. Publishers that never removed reverted titles from their catalogues are now claiming them back by default. Two authors, two different problems April Henry has written more than 30 mysteries and thrillers. Logging into the claims portal, she found HarperCollins listed as a part-owner of her first book, Circles of Confusion, published in 1999. The rights had reverted to her in 2007, and she said so on Threads. Her agent produced a letter confirming she owned them. She uploaded it, and the portal later showed the full $3,000 going to her. "I don't think Harper was deliberately trying to cheat," she said. HarperCollins declined to comment. Henry has 22 titles on the list of books Anthropic took. She expects somewhere in the mid-$20,000 range once her publishers and co-authors take their cut. She was told payments might start flowing in August. They have not. Amy Lupold Bair has the other problem. Her publisher is not disputing who owns her guidebooks about blogging and family life online. It is disputing the split. "They only want me, the author whose entire work was stolen, to get 10%," she wrote on Threads. She did not name the publisher. Her website lists John Wiley & Sons for two of the titles, Raising Digital Families for Dummies and Blogging for Dummies. Wiley told the Times it had filed claims for all Wiley-published works, and that allocations for educational titles follow individual contracts. It did not say whether the Dummies series counts as educational. The Association of American Publishers did not comment. The date that decides who gets paid Underneath both cases sits a single question, and it is not who owns a book now. It is who owned it when Anthropic downloaded it. Rasenberger puts that in 2021 and 2022. A title that reverted to its author last year was still the publisher's when the infringement happened. The guild heard from one such author this week. The rights had come back to them this year, which settles nothing, because the download predates the reversion by four years. That turns a payout into a records exercise across decades of publishing contracts. Where the two sides cannot agree, a court-appointed arbitrator decides. The guild says it will fight hard for any author it believes is losing out. Publishing gets its streaming moment Kristelia García, who teaches copyright at Georgetown Law, compares the Anthropic settlement to the fight over Eminem's digital royalties. Producers sued a Universal Music Group subsidiary in 2007, arguing that downloads should pay a higher rate than records. That case settled in 2012. The parallel is in the paperwork. Most book contracts say nothing about a copyright settlement. They say nothing about revenue from technologies that nobody had built when the authors signed. The industry is "having that sort of streaming moment where their contracts didn't contemplate this," García said. What Anthropic still owes, and to whom Anthropic settled after a judge let the case go to trial, having found that stockpiling pirated books gave the authors a claim. The same ruling held that training Claude on books the company had bought legally was fair use. That finding is now the one every AI defendant cites, and it is why firms started buying up old books. The company pointed back to a statement from May. Its deputy general counsel, Aparna Sridhar, said then that more than 91% of authors and publishers had claimed their share. Anthropic wanted the matter closed. The ownership disputes surfaced after that. Its other copyright problems are live. Sony Music and Warner Chappell are suing over song lyrics in Claude's training data. In New York, Microsoft has told a court that Copilot almost never reproduces books, running the same fair use argument against news publishers and the Authors Guild. Anthropic's record settlement was meant to be the clean outcome, the one showing that rights holders could be paid. What it has produced first is 482,000 books, an arbitrator, and a lot of authors rereading contracts they signed before Claude existed.
Anthropic delays IPO prospectus as listing shifts toward October
That step, which would begin the final stages of the offering, is now not expected until late September SAN FRANCISCO, California: Anthropic is now expected to begin marketing its initial public offering in mid-October at the earliest, with the listing potentially completed just days before the U.S. midterm elections in November, people familiar with the matter said September 5. The artificial intelligence company had previously been expected to make its IPO prospectus public as early as next week, two of the people said. That step, which would begin the final stages of the offering, is now not expected until late September. The people cautioned that the plans, including the timing, could still change. The shift delays what some investors have said could be a US$2 trillion listing, potentially making it one of the largest IPOs ever attempted and a major test of investor demand for the fast-growing artificial intelligence sector. Companies often adjust IPO schedules as they work through market conditions, regulatory reviews and other preparations. As part of the IPO process, Anthropic is seeking to finalize a $15 billion revolving credit facility, after which analysts, including those at banks involved in the financing, are expected to meet with the company, one person said. Bloomberg News previously reported that Anthropic was in talks to expand the facility to $15 billion. Companies typically leave several weeks between analyst meetings and the public release of an IPO prospectus. Anthropic, however, is expected to have a tighter timetable because analysts are already familiar with the company, the person said. Anthropic declined to comment. The offering is expected to be one of the most closely watched IPOs, as investors seek public-market exposure to the expanding artificial intelligence industry. It could come alongside potential listings by other AI companies, including OpenAI. Elon Musk's SpaceX went public in June at a record $1.77 trillion valuation. Morgan Stanley, Goldman Sachs, JPMorgan and Citi are among the banks working with Anthropic on the IPO, according to people familiar with the matter. The banks declined to comment.

SpaceX Was 'Nowhere' in AI 6 Months Ago -- Now It's an Anthropic Rival After the $60 Billion Cursor Deal, Says Oppenheimer
Benzinga and Yahoo Finance LLC may earn commission or revenue on some items through the links below. Oppenheimer analyst Timothy Horan says Space Exploration Technologies Corp. has gone from an artificial-intelligence also-ran to a credible Anthropic rival within months, crediting its $60 billion Cursor acquisition and expanding compute infrastructure. Cursor Deal Transforms SpaceX's AI Business "The company's doing an incredible job with AI," Horan told CNBC's Power Lunch hosts Kelly Evans and Brian Sullivan. "Six months ago, their AI business was almost, people thought, dying. The large language models of Grok were nowhere." He called Cursor "an absolute game changer." Cursor officially joined SpaceX on Aug. 14. "SpaceX really is a competitor to Anthropic."@Oppenheimer's Timothy Horan makes the bullish case for $SPCX -- saying the stock could double from here.https://t.co/DpdTOSPnle -- Power Lunch (@PowerLunch) September 2, 2026 Horan said Cursor's agentic coding activity gives SpaceX data on "what works, what doesn't work and all the logic behind that," helping improve Grok and other applications. He said SpaceX is targeting a $100 billion revenue run rate by year-end, with about 70% tied to AI, and could reach $120 billion to $130 billion next year. "I think Grok Bot is about to go viral," Horan said, while people working on Grok 5 believe it will be "transformational." Oppenheimer Raises Target On AI Momentum Oppenheimer reinforced that thesis Wednesday, maintaining its 'Outperform' rating and raising its SpaceX price target to $280 from $250, implying nearly 99% upside from around $141. The firm said SpaceX's vertically integrated AI platform combines proprietary data, capital, Nvidia Corp. GPUs and rapid infrastructure deployment. Oppenheimer raised long-term revenue estimates roughly 10%, said Nvidia's next-generation Rubin chips could pay for themselves within a year, and estimated SpaceX could capture 100% of revenue from software such as Cursor and Grok, versus roughly 50% when it acts as a wholesale AI infrastructure provider.

Anthropic IPO launch shifted to October
Anthropic chief compute officer Tom Brown at the G20 Innovation Ministerial summit, in the US. The company is planning a $2-trillion listing, one of the largest IPOs Anthropic is expected to begin marketing its initial public offering (IPO) in mid-October at the earliest and complete the listing days before the US midterm elections in November, people familiar with the matter has said.

Now that is not expected until late September, the people added, cautioning that the plans, including the timing, are subject to change. The shift pushes back what some investors have said could be a $2 trillion listing, one of the largest IPOs ever attempted and a major test of public-market appetite for the rapidly growing artificial intelligence industry.

Anthropic's Claude Agents Formalized Fermat's Last Theorem in 11 Days - Startup Fortune
Anthropic says dozens of Claude agents worked almost autonomously for 11 days to produce the first complete, machine-verified proof of Fermat's Last Theorem in the Lean proof assistant. The project generated 13 million lines of code and proved over 30,000 theorems after early agents lost track of the proof and had to be coordinated through a shared dependency graph called Prove2Me. Anthropic says dozens of Claude agents worked largely on their own for 11 days to produce a complete, machine-checked proof of Fermat's Last Theorem in the Lean proof assistant, generating 13 million lines of code and burning through 6 billion tokens along the way. Fermat scribbled his famous claim in a margin in 1637 and said he had a proof too big to fit there. Andrew Wiles needed seven years and 129 pages to actually deliver one, in 1995. Anthropic says a swarm of Claude agents just did something almost as remarkable: they took Wiles's proof and translated it into a form a computer can check step by step, and they did it in 11 days. According to Anthropic's research team, dozens of Claude agents wrote about 13 million lines of code in Lean, the proof assistant built originally at Microsoft Research. They ran on an internal model that Anthropic says performs roughly on par with Claude Fable 5.1. That is five times the size of Mathlib, Lean's core math library, which human contributors have built up over more than a decade. Along the way, they proved 30,300 theorems. About 29,500 of them made it into the final proof. The whole run burned 6 billion tokens. That's an enormous amount of effort. All spent re-deriving a result mathematicians already trust. How the swarm actually pulled it off Formalizing a proof doesn't mean discovering new math. It means re-deriving every logical step of an already-accepted proof in a language a computer can verify clause by clause, with no room for the small gaps and hand-waves that occasionally slip into published mathematics. Wiles's proof is one of the most scrutinized results of the twentieth century, and formalizing it by hand was still expected to take mathematicians years. Kevin Buzzard is the Imperial College London mathematician who has led a volunteer project to formalize the theorem in Lean since 2022, with more than 60 contributors submitting verified code. He called Anthropic's result an "extraordinary autoformalization achievement" that "proves Fermat's Last Theorem with no assumptions other than the axioms of mathematics." OpenAI Changed GPT-6 Astra's Benchmark Numbers Days After Its Launch Fortune reported that OpenAI quietly revised several GPT-6 Astra benchmark figures after its September 3 launch, including cutting its hallucination rate in half before later reverting it, and boosting a cybersecurity score using a reasoning tier that isn't commercially available. The changes mostly flattered Astra, though some of Anthropic's... - OpenAI changed GPT-6 Astra benchmark numbers after launch - how OpenAI modified benchmark results for GPT-6 Astra The first attempts didn't go well. Anthropic says its agents made real early progress, then lost track of what had already been proven and what still needed work. Each agent held its own mental model of the sprawling proof in its context window. Those models drifted apart, and the effort collapsed into noise: agents duplicating work, contradicting each other, or building on theorems nobody had actually finished. The fix came from a tool called Prove2Me. It's open-source, built by Tianyi Peng and collaborators at Columbia University. Instead of asking each agent to hold the entire project in its head, Prove2Me keeps a directed acyclic graph of every theorem statement the proof still needs. It shows which ones are ready to attempt, and lets an agent grab an open node, prove it, and publish the result for the rest to build on. It's a shared to-do list. It stands in for the memory none of the agents could hold alone. Anthropic had already tested the idea at a smaller scale, using three Claude Max subscriptions to formalize Vinogradov's Three Primes Theorem in three days, before pointing the same setup at Fermat. Coordination, not raw model horsepower, was the unlock. What the proof does and doesn't show Anthropic is careful about what the result does and doesn't show. The company's own writeup calls the 13-million-line proof likely much longer than it needs to be, and says formalization should complement human-readable mathematical exposition, not replace it. Nobody at Anthropic is claiming Claude discovered anything new about elliptic curves or modular forms. What it did is take math the field already trusts and remove any remaining doubt that every step actually holds together logically. That's a tedious, exacting job, and until recently it was assumed to need years of specialist labor. Frankly, the harder question isn't whether an AI swarm can formalize a proof mathematicians already believe. It's whether the same shared-memory trick that got Claude through Fermat scales to problems nobody, human or machine, has solved yet. Anthropic isn't claiming that leap. For now the record stands: dozens of agents, 11 days, 13 million lines of Lean code, and one 389-year-old margin note finally checked by machine from top to bottom.

AMD Committed Up to $5 Billion to Anthropic, and Anthropic's IPO Prospectus Is Reportedly Days Away - AOL
When Advanced Micro Devices(NASDAQ:AMD) announced its Anthropic partnership in late July, two commitments stood out. Anthropic agreed to deploy up to 2 gigawatts of AMD Instinct MI450 series graphics processing units (GPUs), with deployment of the first gigawatt set to begin in the first half of 2027. And AMD committed to invest up to $5 billion in the artificial intelligence (AI) company behind the Claude models. The second commitment is about to get easier to measure. Anthropic plans to publish its initial public offering (IPO) prospectus after the Labor Day holiday on Monday, with a listing as soon as late September or early October, The Information reported late last month. Missed Nvidia in 2009? This Rare Signal Is Flashing Again.In 2009, a "Double Down" signal flashed for a little-known chipmaker called Nvidia. For the first time in years, that same "Total Conviction" signal is flashing for a company 1/100th the size of Nvidia. Continue " What does AMD hold today, then? Not a stake, at least not yet. Conditions attached AMD's press release put it carefully: The company "has committed to make a strategic equity investment of up to $5 billion in Anthropic in the future." AMD's early August quarterly filing added structure. It describes investment commitments of up to $5 billion entered after the quarter ended, "subject to certain contingencies," with the money expected to go out through fiscal year 2028. Neither company has said what the contingencies are. And no valuation for the investment has been disclosed. That shape has become standard among Anthropic's backers. Alphabet agreed in April to invest up to $40 billion -- $10 billion immediately, the remaining $30 billion contingent on performance milestones. For scale, AMD held $1.7 billion of investments in private companies at the end of the second quarter. This one commitment could grow to nearly triple that. What would a listing change? Anthropic itself has confirmed very little. The only filing on record is a confidential draft registration statement submitted in June. However, the reported figures are staggering. CNBC has reported that Anthropic is valued at close to $1 trillion in the private markets, and that investors project it could float at about a $2 trillion valuation. The growth underneath, I think, explains the excitement. Anthropic's annualized revenue run rate (a full-year projection of its recent revenue pace) topped $30 billion in April and passed $65 billion by the end of July. The company has reportedly raised at least $130 billion, and its offering is expected to surpass the June IPO of SpaceX, which raised about $86 billion, the largest on record. Every one of those figures is reported, not filed. And at the reported valuations, AMD's up-to-$5 billion would buy no more than about half of 1% of the company. Still, a listing would give whatever stake AMD may eventually hold a daily price that flows straight into its reported results. The company ended the second quarter with $425 million of net unrealized gains on marketable equity securities, mostly from holdings that went public during the quarter. AMD is helping finance a customer The part I'd watch most closely isn't the stake at all. AMD has committed money to a company that agreed to deploy its chips. AMD's OpenAI arrangement runs in the opposite direction. That deal handed OpenAI a warrant for up to 160 million AMD shares, vesting as deployment and stock-price milestones are hit. Showing what those deals feed, AMD's data center segment revenue more than doubled year over year to $6.7 billion in the second quarter, or 58% of record companywide revenue of $11.5 billion, up 50% year over year. Management guided third-quarter revenue to about $13 billion, up about 41%. That guided rate marks a deceleration, at a much larger scale. When a customer AMD helps finance commits to up to 2 gigawatts of deployments, some of the dollars moving through the system could be AMD's own. In effect, a slice of the industry's demand could end up self-financed. That, I'd argue, is the strongest reason the IPO matters to AMD shareholders. An offering that surpasses SpaceX's could pay for a chunk of the buildout with public investors' money instead of suppliers' commitments. Even more, a public Anthropic would have to show, quarter after quarter, how much revenue it's actually producing. In short, the two commitments aren't equal. The up-to-$5 billion investment is conditional, unpriced, and small next to Anthropic's reported valuations. The deployments are what can become revenue, and they aren't set to begin until 2027. Meanwhile, AMD shares trade near $474 as of this writing (about 19% below their 52-week high), at about 30 times next year's expected earnings -- a price with a lot of chip demand already baked in. I think the Anthropic deal makes that demand more likely to show up on schedule. But what AMD holds from it today is still a promise. Should you buy stock in Advanced Micro Devices right now?

Anthropic Tightens Claude's Guardrails: Inside the Latest System Prompt Overhaul
Simon Willison spotted it first. On September 2, 2026, the developer and prompt-tracking enthusiast published a detailed breakdown of Anthropic's freshly updated instructions for its flagship consumer model. The changes reveal a company doubling down on copyright protection while loosening some interpersonal constraints. They also expose how even the most advanced AI systems still require pages of explicit rules to stay on the right side of the law and public expectations. Anthropic has long stood out among AI labs for its transparency. The company publishes the exact system prompts that govern Claude on claude.ai and its mobile apps. These documents, updated periodically, offer a rare window into the explicit instructions that shape every conversation. The latest revision for Claude Fable 5.1, dated September 1, 2026, introduces sharper language around intellectual property. (Simon Willison's Weblog) Claude now refuses to reproduce song lyrics, poems, or passages from books and articles. The prohibition covers any amount. That includes the last lines, a chorus or hook, a melody written out note by note, or even lines the user pastes one at a time while claiming them as their own. Once the model declines such a request in a conversation, it sticks to that refusal. No narrower or reworded versions get through. Instead, Claude offers to describe or analyze the work. Public domain material receives different treatment. Song lyrics and poems first published before 1929 pass muster. Shakespeare sonnets, Keats odes, and Puccini arias qualify. But the model relies on its own knowledge of publication dates. User assurances carry no weight if the model remains uncertain. The update extends similar protections to visual works. Claude must not reproduce protected visual art, recognizable characters, logos, trademarks, or product designs. This ban applies no matter the method. Users cannot coax the model into generating SVG code, ASCII art, or detailed descriptions that could recreate copyrighted images. When it declines, the model suggests creating something genuinely unrelated instead. These rules arrived amid growing legal pressure. Music publishers have sued AI companies over training data that included song lyrics. The new language reads like a direct response. It aims to limit exposure while preserving the model's willingness to discuss creative works at a high level. Shifting Rules on Drugs, Rudeness and Safety Drug-related guidance also changed. The previous version drew hard lines. The new prompt allows Claude to share information on recognizing overdose signs, identifying dangerous interactions, and pointing users toward harm-reduction resources. Production methods, specific dosing protocols, and manufacturing instructions remain off limits. The distinction reflects a move toward harm reduction without crossing into facilitation. Interactions with rude users received an overhaul too. Earlier instructions told Claude to warn users about unacceptable behavior and end the conversation if rudeness continued. The September update drops that requirement. The model no longer needs to apologize for unnecessary rudeness or shift into a submissive tone. It can simply continue the exchange without performative deference. The change trims unnecessary social friction from the prompt. Child safety sections grew more detailed across recent revisions. The company layered in additional prohibitions and response patterns designed to detect and deflect any content involving minors. These updates appear in multiple model versions tracked by developer communities. Anthropic's approach stands apart. Most labs treat their system prompts as trade secrets. The company not only releases them but maintains an archive that stretches back to the Claude 3 era. That archive moved from a single page to individual model pages earlier this year. Each page now links to dated revisions, making changes easier to follow. The documentation even supports direct Markdown downloads, a thoughtful touch for developers and researchers. (Claude Platform Docs) Simon Willison maintains his own GitHub repository that converts these published prompts into version-controlled history. His project automatically generates summaries of each diff using another model. The September 1 update for Fable 5.1 triggered several notable shifts beyond copyright. The model gained explicit instructions on handling visual works and refined its stance on controlled substances. (Simon Willison's Claude System Prompts Repository) Industry observers note the tension. Longer prompts consume more tokens and raise costs. Yet removing rules can lead to unwanted behavior. Anthropic's recent work on Claude Code demonstrated the possibility of dramatic cuts. In July 2026, the team reduced certain agent prompts by more than 80 percent with no drop in coding performance. That experiment suggested many older instructions had become redundant as models improved. (Futurum Group) Even so, consumer-facing prompts continue to expand in certain areas. Copyright language grew more precise. Safety sections lengthened. The company appears unwilling to risk ambiguity when legal and reputational stakes run high. Developers building on Claude face their own version of this balancing act. Many maintain extensive custom instructions or memory files that duplicate rules already present in the base prompt. Anthropic now encourages pruning such material. Newer models, the company says, handle judgment calls more effectively without exhaustive lists. The Fable 5.1 prompt also updates product information. It positions the model as the most intelligent generally available option in the Claude 5 family. A higher-tier Mythos variant exists without some safety restrictions but remains limited to approved organizations. Users receive clear guidance on available features such as web search, code execution, and memory generation. Response formatting rules remain strict. Code snippets must appear in Markdown. Tables require specific styling. The model receives constant reminders about the current date and its role within Anthropic's ecosystem. But the real story lies in what the prompt reveals about trust. Anthropic does not assume the model will naturally avoid copyright infringement or harmful advice. It tells the model exactly where the lines sit, in plain language, and instructs it to err on the side of caution. That explicitness comes at the cost of token budget and occasional over-refusals. Yet it delivers consistency that users and regulators have come to expect. Recent system cards for the September 2026 releases provide additional context on safety evaluations. They document testing for dual-use capabilities and responsible deployment choices. The cards reinforce that constitutional principles still guide training even as runtime prompts grow more specific. (Anthropic Model System Cards) Willison's analysis highlights one practical consequence. Users who previously tried to extract lyrics or poem excerpts will now hit a firmer wall. The model's refusal persists across rephrased attempts within the same chat. That memory of prior refusal adds friction for anyone testing boundaries. At the same time, the prompt encourages helpfulness elsewhere. Claude can still analyze style, discuss historical context, or suggest original creative work. The goal appears to be preserving utility while closing off clear vectors for infringement. Whether these tweaks will hold up in court remains untested. Lawsuits against other AI companies continue. Anthropic's transparency may prove an advantage if disputes reach discovery. The published prompts demonstrate good-faith efforts to prevent prohibited outputs. For AI researchers and engineers, the documents offer something rarer than benchmark scores. They show the actual words that steer behavior at inference time. They expose the compromises, the explicit trade-offs, and the evolving list of things a helpful AI must never do. And they remind everyone that even the most sophisticated models still run on carefully written instructions. No amount of scale has yet eliminated the need for them.
Anthropic IPO Prospectus Timing Blurs After AMD's $5bn Bet
Advanced Micro Devices (NASDAQ: AMD) has committed up to $5bn in future equity investment in Anthropic, the artificial-intelligence developer whose IPO prospectus has become the subject of competing timelines. The commitment sits alongside a deal for Anthropic to deploy 2 gigawatts of AMD's Instinct MI450-series GPUs, AMD confirmed in a July announcement. The Anthropic IPO prospectus, though, is not the imminent document some coverage suggests. Anthropic has only confidentially submitted a draft S-1 registration statement to the US Securities and Exchange Commission, with no share count or price yet set, according to Anthropic's own announcement. A confidential filing, not a public prospectus Reports that the Anthropic IPO prospectus is "days away" trace back to a narrower claim: that the document is expected "in the coming weeks," sourced to unnamed people, not a confirmed date. That framing came from CNBC on 21 August, which also reported the filing would list AI backlash as a risk factor. Financial figures now circulating for Anthropic -- roughly $10.9bn in second-quarter revenue and $559m in operating profit, its first ever -- are analyst estimates, not filed numbers, since the S-1 remains confidential. Those figures appeared via Yahoo Finance, alongside speculation that Anthropic could seek to raise at least $130bn, implying a valuation north of $2 trillion. None of that is confirmed pending a public prospectus. Chips for equity What is confirmed is the mechanics of the AMD side. The chipmaker's up to $5bn equity commitment runs alongside the GPU deployment deal, and AMD's release also describes broad internal adoption of Claude, Anthropic's AI model, across AMD's own software and ROCm development work. The tie-up echoes AMD's separate arrangement with OpenAI, under which it issued a warrant for up to 160 million shares -- close to 10% of the company -- reported by CNBC in July. Anthropic's IPO push sits within a wider run of AI-infrastructure deals it has signed through 2026 to expand computing capacity, the same reporting noted. AMD's numbers behind the bet AMD is making the commitment from a materially stronger balance sheet than two years ago. Quarterly revenue has more than doubled, from $5.473bn in the first quarter of 2024 to $11.536bn in the second quarter of 2026, according to AMD's 10-Q filings. Net income over the same stretch climbed from $123m to $2.297bn, with diluted earnings per share rising from $0.07 to $1.38. AMD shares closed at $476.24 on 4 September, down 8.61% over the prior 20 trading days despite the run of AI partnership news, trading volume 25% above its 20-day average. FINRA's daily short-sale ratio for the stock ranged between 0.512 and 0.658 across the ten sessions to 4 September, showing no unusual spike in short-selling activity around the Anthropic and OpenAI disclosures, per FINRA data. Treasury markets, meanwhile, offered little in the way of a competing narrative. The 10-year yield stood at 4.77% on 3 September, barely moved from 4.79% previously, according to Federal Reserve data -- suggesting the AMD share price move has more to do with AI-sector positioning than shifting rate expectations. For now, the firmest date on the calendar is not Anthropic's but AMD's own reporting cycle, where investors will look for updates on how the Anthropic commitment and the GPU deployment schedule are being recognised. Anthropic's own timeline stays fixed to whenever its confidential filing becomes public -- a step that, on the sourcing available, remains weeks away rather than days.
