Anthropic Closes $30 Billion Round at $900 Billion Valuation, Surpassing OpenAI
The Claude maker has raised more than $72 billion in its lifetime, closing the largest private AI funding round in history as quarterly revenue surpasses $10 billion.

Anthropic has closed what is now the largest private funding round in the history of artificial intelligence, raising more than $30 billion at a pre-money valuation above $900 billion. The round, which Bloomberg first reported was expected to close in late May, was confirmed by multiple sources familiar with the transaction over the weekend of May 24–25, 2026. The close formally positions Anthropic as the world's most valuable private AI company, surpassing OpenAI's $852 billion private market valuation from March.
The Numbers Behind the Valuation
The valuation is not speculative. It is anchored in financial projections that, by the standards of any previous technology company at this stage of development, are extraordinary. Anthropic projected $10.9 billion in Q2 2026 revenue, representing a 130 percent increase from Q1's $4.8 billion. More significantly, the company is approaching its first quarterly operating profit — projected at approximately $559 million for Q2 — after years of operating at a loss while building out its model infrastructure.
Compute costs, which have been the defining constraint on AI company economics, are falling faster than most analysts expected. Anthropic's compute spend as a fraction of revenue dropped from 71 cents per revenue dollar in Q1 to a projected 56 cents in Q2. If that trajectory continues, the company's path to sustained profitability becomes credible within the next two to three quarters.

Who Invested and Why
The round was co-led by four firms: Sequoia Capital, Dragoneer Investment Group, Altimeter Capital, and Greenoaks Capital Partners, each committing approximately $2 billion. Peter Thiel's Founders Fund and General Catalyst also participated. The round came together in under four weeks from first investor outreach to close — a pace that Bloomberg described as unusually fast for a transaction of this size.
Three of the four co-leading investors are also prior OpenAI backers. That detail is not incidental. It suggests that sophisticated investors who have seen OpenAI's financials up close have made a deliberate decision to diversify their AI exposure toward Anthropic. Whether that reflects concerns about OpenAI's governance, its competitive position, or simply a desire for portfolio balance is not publicly known. But the pattern is notable.
The strategic rationale for the round is clear: Anthropic is spending at a scale that requires continuous capital infusion. The company is spending $1.25 billion every month on compute from SpaceX alone — a figure that only became public when SpaceX filed its IPO prospectus last week. Add AWS, Google Cloud, and other providers, and the total infrastructure spend is staggering. The new capital provides runway to continue scaling compute while the revenue growth catches up.
Anthropic has now raised more than $72 billion in its lifetime. The last two rounds alone account for $60 billion of that total.

The Competitive Landscape
The funding close reshapes the competitive landscape in ways that are still being absorbed by the industry. Anthropic's $900 billion valuation puts it ahead of OpenAI's last reported private valuation, though OpenAI's IPO filing — submitted to the SEC earlier this month — will provide a more definitive public market assessment. OpenAI has projected annualized revenue of approximately $25 billion and is targeting a valuation between $852 billion and $1 trillion at IPO.
The two companies are competing on multiple fronts simultaneously. Claude 3.7 and GPT-5.5 are in direct competition for enterprise API customers. Anthropic's Claude Code and OpenAI's Codex are competing for the rapidly growing market for AI coding assistants. And both companies are racing to deploy agentic systems — AI that can take actions in the world, not just answer questions — before the other establishes a dominant position.

The SpaceX Connection
One of the more unexpected dimensions of Anthropic's financial picture is its relationship with SpaceX. The $1.25 billion monthly compute spend revealed in SpaceX's IPO filing was not previously public knowledge, and it raises questions about the nature of the relationship between the two companies. Anthropic has been a customer of SpaceX's Starlink-based data infrastructure, but the scale of the spend suggests a deeper integration than previously understood.
This relationship is particularly notable given Elon Musk's complicated history with Anthropic. Musk was an early backer of OpenAI, Anthropic's predecessor organization, before departing acrimoniously. He has been publicly critical of both companies. The fact that Anthropic is one of SpaceX's largest compute customers adds an ironic dimension to that history.
What Comes Next
With $30 billion in fresh capital, Anthropic has the resources to execute on its stated roadmap through at least 2027. The company has indicated plans to significantly expand its compute infrastructure, accelerate its enterprise sales motion, and invest in the interpretability research that distinguishes its approach from competitors. CEO Dario Amodei has consistently argued that understanding what is happening inside AI models — not just what they produce — is essential to building systems that are genuinely safe.
The more immediate question is whether the valuation is justified by the fundamentals. At $900 billion, Anthropic is being valued at roughly 90 times its projected Q2 annualized revenue. That is an extraordinary multiple, even by the standards of high-growth technology companies. The implicit bet is that AI revenue will continue to compound at rates that make today's valuation look conservative in retrospect. Given the trajectory of the past two quarters, that bet is not obviously wrong. But it requires a level of sustained growth that has rarely been achieved in the history of technology.
