How Anthropic suddenly became worth almost $1 Trillion

A jaw-dropping $965 billion valuation now puts Anthropic ahead of OpenAI -- and signals a seismic shift in who controls the future of artificial intelligence.

Anthropic has announced a new funding milestone that places it firmly at the top of the generative artificial intelligence race, raising $65 billion in a Series H round that values the San Francisco-based company at $965 billion -- surpassing its most formidable rival, OpenAI, which was last valued at $852 billion in March.

Anthropic's Valuation More Than Doubles in Months

The numbers are staggering by any measure. Just three months ago, in February, Anthropic was valued at $380 billion. That the company has more than doubled that figure -- reaching nearly a trillion dollars -- in such a compressed window underscores how ferociously investors are chasing stakes in frontier AI companies. The latest round was led by Altimeter Capital, Dragoneer, Greenoaks, and Sequoia Capital, with Coatue and ICONIQ serving as co-leads.

Embedded within that $65 billion are $15 billion in previously committed investments from major cloud hyperscalers, including a $5 billion contribution from Amazon. That investment is part of Amazon's broader pledge to pour up to $25 billion into Anthropic, a bet that comes alongside the startup's commitment to spend more than $100 billion over the next decade on Amazon Web Services infrastructure -- a figure that speaks to the colossal, almost incomprehensible costs now underpinning the AI industry.

Claude Demand Is Outpacing Supply

The financing comes at a moment of genuine strain for the company. Demand for Claude, Anthropic's flagship AI assistant, has outrun the company's ability to deliver it. In recent months, Anthropic has been forced to implement usage limits during peak hours -- a rare and telling admission from a company otherwise projecting confidence. To smooth out the congestion, the company began offering users more computing power during off-peak windows, an incentive structure that speaks to just how tight its capacity constraints have become.

Revenue figures suggest demand is no illusion. Anthropic reported that its annualized run-rate revenue crossed $4.7 billion earlier in May, a figure that reflects accelerating adoption among enterprise customers globally. That trajectory makes the company's near-trillion-dollar valuation more than speculative sentiment -- it reflects a business that is, by AI-industry standards, genuinely scaling.

Strategic Hardware Partners Join the Round

Notably, Anthropic's infrastructure partners -- Micron, Samsung, and SK Hynix -- also participated in the funding round. Their involvement signals that the company's ambitions extend well beyond software. Building frontier AI models demands enormous volumes of specialized memory chips, and having the manufacturers of those components as investors creates a supply-chain alignment that few competitors can match.

An IPO on the Horizon for Anthropic

For all the private-market momentum, attention is increasingly turning toward what comes next. According to people familiar with the company's thinking, Anthropic is laying groundwork for an eventual public listing -- a move that investors and bankers say could come as soon as this year. OpenAI is reportedly on a parallel path, raising the prospect of two landmark AI IPOs arriving in close succession, each testing how public markets value the promise of artificial general intelligence against the reality of enormous ongoing costs.

The rivalry between Anthropic and OpenAI has never been sharper. Both companies continue burning through massive amounts of capital as they race to train and deploy increasingly powerful AI models while competing for the same enterprise customers, cloud partnerships, and elite research talent. Anthropic's latest valuation does not settle the battle -- it raises the stakes. After years of being viewed as the insurgent challenger, Anthropic now carries the bigger valuation, signaling a major turning point in the AI race and intensifying an already fierce competition between two of the industry's most influential players.
