US judge blocks Pentagon's Anthropic blacklisting
August 27(Reuters) - A U.S. judge on Thursday blocked the Pentagon's blacklisting of Anthropic, the latest turn in the Claude maker's high-stakes fight with the military over AI safety on the battlefield. Anthropic's lawsuit in California federal court alleges that Defense Secretary Pete Hegseth overstepped his authority when he designated Anthropic a national security supply-chain risk, a label the government can apply to companies that expose military systems to potential infiltration or sabotage by adversaries. Hegseth's unprecedented move, which followed Anthropic's refusal to allow the military to use AI chatbot Claude for U.S. surveillance or autonomous weapons, blocked Anthropic from certain military contracts. Anthropic executives have said it could cost the company billions of dollars in lost business and reputational harm. Anthropic says that AI models are not reliable enough to be safely used in autonomous weapons and that it opposes domestic surveillance as a violation of rights, but the Pentagon says private companies should not be able to constrain military action. U.S. District Judge Rita Lin, an appointee of former Democratic President Joe Biden, made the ruling in a 59-page order where she found that the Pentagon's decision was "illegal and baseless." "The empty invocation of national security is not a blank check to punish and retaliate against government critics," she wrote. Anthropic's designation was the first time a U.S. company has been publicly designated a supply-chain risk under an obscure government-procurement statute aimed at protecting military systems from foreign sabotage. In its March 9 lawsuit, Anthropic alleged the government violated its right to free speech under the First Amendment of the Constitution by retaliating against its views on AI safety. The company said it was not given a chance to dispute the designation, in violation of its Fifth Amendment right to due process. The lawsuit says the decision was unlawful, unsupported by facts and inconsistent with the military's past praise of Claude. The Justice Department countered that Anthropic's refusal to lift the restrictions could cause uncertainty in the Pentagon over how it could use Claude and risk disabling military systems during operations, according to a court filing. The government said the designation stemmed from Anthropic's refusal to accept contractual terms, not its views on AI safety. Anthropic has a second lawsuit pending in Washington, D.C., over a separate Pentagon supply-chain risk designation that could lead to its exclusion from civilian government contracts.

Judge Rules Trump Administration's Blacklisting of Anthropic Was Illegal
Sign up for the On Tech newsletter. Get our best tech reporting from the week. Get it sent to your inbox. The Trump administration acted illegally when it labeled the artificial intelligence start-up Anthropic a security risk and barred the company from working with the U.S. government, a federal judge ruled on Thursday. Judge Rita Lin of the U.S. District Court in the Northern District of California wrote in her 59-page ruling that the government had unlawfully retaliated against Anthropic "for constitutionally protected expressive activities" after the A.I. company spoke out about how its technology should be used. "The empty invocation of national security is not a blank check to punish and retaliate against government critics," she wrote. In a statement, Anthropic said it was "pleased the court has ruled that this supply-chain risk designation was unlawful." "We remain focused on working productively with the government to harness A.I. for our national security so all Americans benefit from this technology," the statement added. The Trump administration did not immediately respond to a request for comment. The ruling caps the first of two lawsuits that Anthropic filed in March in response to the Trump administration's action. The second lawsuit, filed in the U.S. Court of Appeals for the District of Columbia Circuit, is ongoing. The Trump administration could appeal Judge Lin's ruling or wait for a decision in the second lawsuit before taking action, a person with knowledge of the matter said. The San Francisco ruling is the latest chapter in the fight between the Trump administration and Anthropic, which is heading toward what may be the biggest-ever initial public offering. The two sides came to blows at the start of the year over a $200 million contract to provide the Pentagon with A.I. technology on classified systems. Anthropic, which is based in San Francisco, insisted that its technology not be used in mass surveillance of Americans or for autonomous lethal weapons. The Pentagon said a private company could not establish policy for the U.S. government. The two sides could not come to an agreement. Defense Secretary Pete Hegseth then announced that Anthropic was a "supply chain risk," a formal designation that had previously been used against foreign companies that the government deemed a national security risk. The designation meant no contractor or supplier that works with the military can do business with Anthropic. On March 9, Anthropic filed two lawsuits to challenge the government designation, arguing that the legal statutes for labeling a company a supply chain risk were narrow and did not apply to American firms. The company also said the label was ideologically motivated to penalize Anthropic, and that the company's First Amendment rights were being violated. Before her ruling, Judge Lin had said the Pentagon's argument that Anthropic's public criticism of the government justified banning the A.I. company from federal work was "really troubling." She also said she saw no evidence to the government's claims that Anthropic could "flip some kind of kill switch" to potentially disable or alter its A.I. models during war.

Anthropic planned, then abandoned US$7 billion purchase of AI chip startup MatX: sources
[SAN FRANCISCO] Anthropic discussed buying artificial intelligence chip startup MatX for roughly US$7 billion, seeking to accelerate efforts to develop custom hardware for its fast-growing AI business, two people briefed on the matter told Reuters. The merger talks, which a third person said have evolved into a discussion about a partnership, underscore the AI lab's ambition to secure the resources and talent needed to build its own chips. The goal is to help Anthropic accelerate its in-house chip development. Reuters is reporting on the discussions for the first time but could not learn why the talks are no longer active. MatX, founded by former Google tensor processing unit (TPU) engineers, is now seeking to raise new capital at a valuation of about US$4 billion, one of the people said, requesting anonymity to discuss private matters. Anthropic declined to comment on deal talks with MatX. MatX did not respond to a request for comment. Chip plans on road to IPO As Anthropic scales its Claude family of AI models, the company is looking to produce hardware that can fulfill its voracious appetite for data crunching and reduce its reliance on chips produced by Nvidia. Anthropic, which is expected to list in 2026, has hired engineering and executive talent to accelerate the chip design process, which could take years. Anthropic's IPO, expected months after SpaceX went public with a US$1 trillion valuation, will chase a valuation of US$2 trillion, which hinges on a 2028 revenue figure of as much as US$200 billion, Reuters reported earlier in August. Anthropic said it is expanding an in-house silicon team to design custom chips that will allow Claude models to run faster and more efficiently. It also plans to keep a multi-chip approach by working with providers from Nvidia to Google. Designing chips is expensive and time-consuming. It can take a year or more to produce a viable piece of hardware, and design costs for a single generation run in the hundreds of millions of dollars. An acquisition of an AI chip startup such as MatX would give Anthropic in-house design expertise and could help lower costs over the longer term, the people said. MatX has been working on a chip that would be useful for building large AI models in a process called training. Anthropic plans to spend tens of billions of dollars to rent computing power from cloud providers and also plans to buy chips directly. It plans to buy US$36 billion worth of Google's AI chips, and signed a US$45 billion deal to rent AI cloud computing power from Nscale. It agreed to pay SpaceX US$1.25 billion per month through May 2029 for computing capacity across its data centre clusters. D with other AI chip startups The discussions with MatX also suggest Anthropic may be interested in producing a training chip, while other chip startups and rival OpenAI pursue processors better suited to generating responses from chatbots, a process known as inference. Anthropic could elect to produce an inference chip as well, the sources said. In recent weeks, Anthropic held meetings with a range of AI chip startups. It has not yet elected to make an acquisition. The meetings are an attempt by Anthropic's engineers and executives to understand the current range of chip design approaches. On Aug 22, Anthropic hired Google chip veteran Amir Salek as part of the company's push into hardware. In June, the AI lab hired former OpenAI chip engineer Clive Chan who worked on the OpenAI chip unveiled earlier in 2026. The leading AI labs such as Anthropic and OpenAI have become increasingly focused on custom chips, which can be tailored to their models and workloads. Through this, they hope to create significant performance and economic advantages. At a conference on Wednesday (Aug 26), OpenAI boasted that its first custom chip called Jalapeno outperformed a similar processor made by Nvidia. OpenAI executives noted that the chip was more energy efficient in performing inference calculations. Making a custom chip may also help Anthropic hedge against the tight supply of Nvidia's processors, which Nvidia said in a conference call on Wednesday would be in short supply through 2027. Google has developed TPUs, while Amazon has built its Trainium and Inferentia chips. Anthropic was one of the first companies to run its models on hardware from several vendors including Nvidia, Google and Amazon. The company has been seeking more computing capacity to meet surging demand for its models, including through a deal with SpaceX to use its Colossus 1 facility, which houses more than 220,000 Nvidia chips.

The government said the designation stemmed from Anthropic's refusal to accept contractual terms, not its views on AI safety. Anthropic has a second lawsuit pending in Washington, D.C., over a separate Pentagon supply-chain risk designation that could lead to its exclusion from civilian government contracts.

US judge blocks Pentagon's Anthropic blacklisting
August 27: A U.S. judge on Thursday blocked the Pentagon's blacklisting of Anthropic, the latest turn in the Claude maker's high-stakes fight with the military over AI safety on the battlefield. Anthropic's lawsuit in California federal court alleges that Defense Secretary Pete Hegseth overstepped his authority when he designated Anthropic a national security supply-chain risk, a label the government can apply to companies that expose military systems to potential infiltration or sabotage by adversaries. Hegseth's unprecedented move, which followed Anthropic's refusal to allow the military to use AI chatbot Claude for U.S. surveillance or autonomous weapons, blocked Anthropic from certain military contracts. Anthropic executives have said it could cost the company billions of dollars in lost business and reputational harm. Anthropic says that AI models are not reliable enough to be safely used in autonomous weapons and that it opposes domestic surveillance as a violation of rights, but the Pentagon says private companies should not be able to constrain military action. U.S. District Judge Rita Lin, an appointee of former Democratic President Joe Biden, made the ruling in a 59-page order where she found that the Pentagon's decision was "illegal and baseless." "The empty invocation of national security is not a blank check to punish and retaliate against government critics," she wrote. Anthropic's designation was the first time a U.S. company has been publicly designated a supply-chain risk under an obscure government-procurement statute aimed at protecting military systems from foreign sabotage. In its March 9 lawsuit, Anthropic alleged the government violated its right to free speech under the First Amendment of the Constitution by retaliating against its views on AI safety. The company said it was not given a chance to dispute the designation, in violation of its Fifth Amendment right to due process.

US judge rules Pentagon blacklisting of Anthropic unlawful
WASHINGTON, Aug 27 (Reuters) - A U.S. judge ruled on Thursday that the Pentagon's blacklisting of Anthropic was unlawful. "The undisputed record shows that the challenged actions constituted unlawful retaliation in violation of the First Amendment, and that Anthropic was denied the pre-deprivation process required under the Fifth Amendment," U.S. District Judge Rita F. Lin wrote in a ruling. "The record further shows no material dispute that Secretary Hegseth's decision to designate Anthropic a supply chain risk violated the governing statutory scheme...and was arbitrary and capricious."
