Anthropic raises $13B Series F at $183B valuation

Anthropic, the San Francisco based maker of the Claude family of AI models, said Tuesday it raised $13 billion in a Series F financing that values the company at $183 billion postmoney, nearly tripling its worth since March. The round was led by ICONIQ Capital and coled by Fidelity Management Research Company and Lightspeed Venture Partners, the company said, and drew participation from a long list of institutional investors including BlackRock affiliated funds, GIC, Qatar Investment Authority, Coatue and Ontario Teachers Pension Plan.

The company attributed the fresh funding to rapid commercial traction. Anthropic said its annualized revenue run rate climbed from about $1 billion at the start of 2025 to more than $5 billion by August, and that it now serves more than 300,000 business customers. The number of large enterprise accounts that each generate at least $100,000 in run rate revenue has increased nearly sevenfold in the past year, the company said. Anthropic also highlighted Claude Code, a developer focused product launched in May, as generating more than $500 million in run rate revenue with usage up more than 10 times in three months.
