The numbers behind Anthropic’s rise
A year ago, the biggest and buzziest artificial intelligence start-up around was undoubtedly OpenAI. That’s no longer the case.
Anthropic has taken that crown with its $65 billion fund-raising round. How the company went from also-ran to 900-pound gorilla is a reflection of the current state of the A.I. race, and it raises questions about what comes next.
Where things stand: Anthropic is valued at $900 billion, while OpenAI was last valued at $730 billion, not including the $122 billion it had just raised.
Behind Anthropic’s ascent: The company’s Claude models were consistently highly regarded. But by November, Anthropic’s Claude Code programming tool had become exponentially better at automating software development, driving a surge in adoption.
