Anthropic, the AI startup behind the Claude family of models, has secured a $13 billion Series F financing at a staggering $183 billion post-money valuation, nearly tripling its worth since March.
Anthropic is backed by Amazon and Google-parent Alphabet.
The company said that the round was led by ICONIQ Capital and co-led by Fidelity and Lightspeed Venture Partners, with institutional heavyweights such as BlackRock, GIC, Qatar Investment Authority, Ontario Teachers’ Pension Plan, and Coatue among the backers.
“We are seeing exponential growth in demand across our entire customer base,” Anthropic Chief Financial Officer Krishna Rao said in a statement. “This financing demonstrates investors’ extraordinary confidence in our financial performance and the strength of their collaboration with us to continue fueling our unprecedented growth.”

In early 2025, Anthropic’s valuation stood at $61.5 billion following a $3.5 billion Series E round. Since then, the company’s annualized revenue has surged from $1 billion to over $5 billion, attributed to rapidly growing enterprise adoption of Claude.
Claude Code, Anthropic’s developer-focused AI assistant, has become a standout performer, generating more than $500 million in run-rate revenue within just a few months of its May launch. Its usage climbed over tenfold in that time.
