Anthropic, the company behind the Claude AI model, closed a $65 billion Series H funding round on May 28, bringing its post-money valuation to $965 billion. That makes it the most valuable private company in the AI space, surpassing OpenAI and putting it within spitting distance of the trillion-dollar club.

The company simultaneously reported that its annualized revenue run rate surpassed $47 billion, a figure that jumped substantially from roughly $30 billion in earlier estimates.

Inside the round

The Series H was led by Altimeter Capital, Dragoneer, Greenoaks, and Sequoia. The capital is earmarked for expanding cloud and compute partnerships, as well as scaling Claude for enterprise customers.

Anthropic also announced plans to secure multi-gigawatt TPU deals for compute capacity with Google and Broadcom, with delivery slated for 2027.
