SAN FRANCISCO, May 30, 2026, 04:39 PDT
- Anthropic raised $65 billion in a Series H funding round at a $965 billion post-money valuation, meaning the value includes the new cash invested.
- The deal pushed the Claude maker ahead of OpenAI’s latest $852 billion valuation and landed in a Memorial Day-shortened week when U.S. stocks closed at record highs.
- Investors now face a week of tests: possible Anthropic debt financing, Broadcom earnings and the U.S. jobs report.
Anthropic’s near-$1 trillion valuation gave Wall Street the cleanest number yet for the premium investors are willing to pay for frontier artificial intelligence — and it came while U.S. markets were shut for the weekend after a strong, tech-led week.
The San Francisco-based company said on Thursday it raised $65 billion in Series H funding led by Altimeter Capital, Dragoneer, Greenoaks and Sequoia Capital, valuing the maker of Claude at $965 billion post-money. Run-rate revenue, an annualized sales measure based on current pace, crossed $47 billion earlier in May, the company said.
The timing matters. Wall Street ended Friday with record closing highs, with the S&P 500 up 1.43% for the week and the Nasdaq up 2.39%, helped by chip and technology shares. The NYSE calendar also showed Monday, May 25, was a Memorial Day market holiday, leaving investors to process Anthropic’s funding round in a shortened week.
Anthropic is now valued above OpenAI, which said in March it had closed $122 billion in committed capital at an $852 billion post-money valuation. That puts the two companies in a tighter race for enterprise customers, scarce computing capacity and a possible initial public offering, or IPO, the first sale of shares to public investors.
Reuters reported that Anthropic’s private fundraising coincides with preparations for a public listing, according to investors and bankers familiar with the company, and that both Anthropic and OpenAI could tap public markets as quickly as this year. The new round also follows February’s $380 billion Anthropic valuation, more than doubling the company’s worth in about three months.
“Claude is increasingly indispensable to our growing global community of customers,” Anthropic Chief Financial Officer Krishna Rao said in the company’s funding announcement. He said the money would help Anthropic meet “historic demand,” stay near the research frontier and bring Claude to more workplaces. Anthropic
Lead investors cast the round as a bet on enterprise AI, not just consumer chatbots. Brad Gerstner, Altimeter’s founder and CEO, said Claude’s adoption among “the world’s most demanding organizations” positioned Anthropic for the next phase of AI innovation; Alfred Lin, a partner at Sequoia Capital, said companies were using Claude for complex workflows.

Compute is the hard edge of the story. In AI, compute means the chips and data-center power needed to train and run models. Anthropic said the funding would help expand compute, while Reuters reported separately that Apollo Global Management and Blackstone were working on about $36 billion of debt financing tied to Anthropic’s AI infrastructure, with investors asked to submit orders this week and a possible close next week. Terms could still change.
Amazon is already a central backer and supplier. Reuters reported in April that Amazon would invest up to $25 billion in Anthropic as the AI startup committed to spending more than $100 billion over 10 years on Amazon cloud technology, adding to an earlier $8 billion Amazon investment.
The week ahead will test whether the broader AI trade can keep absorbing large numbers. Reuters reported that investors will watch the May payrolls report due June 5, Broadcom results and bond yields; Liz Ann Sonders, chief investment strategist at the Schwab Center for Financial Research, said a hot jobs report alongside rising inflation could alter the Federal Reserve policy outlook.
The but is simple enough: private valuations can move faster than public-market patience. If enterprise demand slows, AI pricing falls, debt financing tightens or higher bond yields make investors less willing to pay for long-dated growth, Anthropic’s $965 billion mark could become a burden rather than a launchpad. Reuters also noted Anthropic has had to manage peak-hour usage limits, a sign that demand is strong but capacity is still a constraint.
