SAN FRANCISCO, May 30, 2026, 04:39 PDT
- Anthropic has closed a Series H funding round, pulling in $65 billion. The round values the company at $965 billion post-money, which counts the new investment.
- The deal put the Claude maker above OpenAI’s new $852 billion valuation. It came in a week shortened by Memorial Day, with U.S. stocks closing at all-time highs.
- Investors have a string of tests this week, including a possible Anthropic debt deal, Broadcom earnings, and the U.S. jobs report.
Anthropic landed a near-$1 trillion valuation, putting a fresh figure on the premium Wall Street is paying for cutting-edge AI. The number dropped while U.S. markets stayed closed for the weekend after a solid week driven by tech.
Anthropic said Thursday it raised $65 billion in a Series H round led by Altimeter Capital, Dragoneer, Greenoaks and Sequoia Capital. The San Francisco firm, which makes Claude, now carries a post-money valuation of $965 billion. Anthropic said run-rate revenue passed $47 billion earlier in May.
Timing is a factor. Wall Street finished Friday with new record closes, S&P 500 rising 1.43% on the week, Nasdaq up 2.39%. Gains were driven by chip and tech stocks. The NYSE calendar showed Monday, May 25, as a Memorial Day holiday, which meant investors faced a shortened week to digest Anthropic’s funding round.
Anthropic’s valuation now tops OpenAI, which in March reported $122 billion in committed capital and an $852 billion post-money valuation. With those numbers, the competition between the two for enterprise clients, available computing power, and the potential for an IPO—an initial public offering—has narrowed.
Anthropic is raising private funds while also getting ready for a possible public listing, Reuters said, citing investors and bankers close to the company. Both Anthropic and OpenAI may look to the public markets as soon as this year. Anthropic’s new round comes after its $380 billion valuation in February, which more than doubled the company’s value in roughly three months.
Anthropic CFO Krishna Rao said in the company’s funding announcement that “Claude is increasingly indispensable to our growing global community of customers.” Rao said the new money will help Anthropic meet “historic demand,” keep the company close to the research frontier and expand Claude into more workplaces.

Lead backers are pitching the round as an enterprise AI play, not a consumer chatbot deal. Brad Gerstner, founder and CEO at Altimeter, said Claude is catching on with “the world’s most demanding organizations,” setting up Anthropic for the next wave of AI. Alfred Lin, partner at Sequoia Capital, said firms are already tapping Claude for complex work. Anthropic
Compute is still the main story. For AI, compute covers the chips and data center power for model training and deployment. Anthropic said the new funds will help it grow compute. Reuters also reported that Apollo Global Management and Blackstone are arranging about $36 billion in debt backed by Anthropic’s AI infrastructure, with investors’ orders due this week and a potential close next week. Terms are not final.
Amazon is a key backer and supplier. In April, Reuters said Amazon could put as much as $25 billion into Anthropic as the AI company agreed to spend over $100 billion on Amazon cloud tech in the next decade. That’s on top of a previous $8 billion Amazon investment.
AI stocks face a test this week, as investors look to the May payrolls numbers coming out June 5, Broadcom’s earnings, and how bond yields move. Liz Ann Sonders at Schwab Center for Financial Research told Reuters a strong jobs report with higher inflation could shift the Federal Reserve’s stance.
Private values can jump quicker than public markets want. If enterprise demand drops, AI price tags come down, debt gets harder to find or high bond yields push investors away from big growth bets, Anthropic’s $965 billion price tag could end up weighing on it instead of helping. Reuters said Anthropic has faced peak-hour usage caps, showing demand looks strong but capacity still holds them back.
