Anthropic Overtakes OpenAI With $965 Billion Valuation
Anthropic closed a $65 billion round at a $965 billion valuation, leapfrogging OpenAI to become the most valuable AI company.
- Anthropic closed a $65 billion round at a $965 billion valuation.
- The figure tops OpenAI and its $852 billion mark from March.
- Annual run-rate revenue crossed $47 billion.
- The round was led by Altimeter, Dragoneer, Greenoaks and Sequoia Capital.
So who is the most valuable AI company in the world right now? As of this week it is no longer OpenAI. Anthropic, the company behind the Claude assistant, closed a record round and took the top spot.
The $65 billion round, finalized on May 28, gave the company a post-money valuation of $965 billion. That is more than the $852 billion OpenAI was worth in March this year, so Anthropic now holds the title of the most valuable private AI firm.
How did Anthropic pass OpenAI?
The numbers behind the jump are concrete. Anthropic pushed its annual run-rate revenue past $47 billion, up from roughly $10 billion at the end of 2025. That is the kind of growth investors want to see when they commit sums this large.
The round was led by Altimeter Capital, Dragoneer, Greenoaks and Sequoia Capital. Samsung, SK Hynix, Micron, Blackstone and Fidelity also took part, widening the circle around the company to include chip and memory makers.
Of the $65 billion total, $15 billion comes from previously promised investments by major infrastructure providers. That share includes $5 billion from Amazon, a long-standing Anthropic partner.
Claude is becoming increasingly indispensable to our growing global community of customers.
That was how Anthropic chief financial officer Krishna Rao described the new round.
What does it mean for Claude users?
For an everyday user who relies on Claude for work or study, the biggest change is the pace of development. Alongside the round the company announced a new model and on May 29 released Claude Opus 4.8, with stronger results in coding and more complex work tasks.
More money usually means more servers and faster processing, which in the end feels like a steadier assistant and less waiting. The rivalry with OpenAI works in the user’s favor here, since both firms keep pushing their models forward.
The race at the top of the AI market is tighter than ever. Does it matter more to you who is worth the most, or which assistant actually does your daily work better?
