Anthropic has secured a $13 billion Series F funding round, elevating its post-money valuation to $183 billion. The company plans to utilize the new capital to drive enterprise adoption, enhance safety research, and support international growth.
The funding round was co-led by Iconiq, Fidelity Management & Research Company, and Lightspeed Venture Partners, with additional investment from various institutional investors, including Altimeter, Baillie Gifford, BlackRock, Blackstone, Coatue, D1 Capital Partners, Insight Partners, Ontario Teachers’ Pension Plan, and Qatar Investment Authority.
Anthropic CFO Krishna Rao stated in a company blog post that the company is experiencing “exponential growth in demand across our entire customer base.” He added that the financing demonstrates investors’ confidence in Anthropic’s financial performance and their collaboration to fuel its growth.
This recent funding follows Anthropic’s previous raise of $3.5 billion at a $61.5 billion post-money valuation in March 2025. The current fundraise comes after reports that the company was considering raising between $3 billion and $5 billion at a $170 billion valuation.
Anthropic has experienced significant growth, with its annual recurring revenue increasing from $1 billion to $5 billion throughout 2025, driven by increased API usage and enterprise adoption. The AI startup reports serving over 300,000 business customers, with the number of large accounts (each representing over $100,000 in run-rate revenue) growing nearly sevenfold in the past year.
Claude Code, Anthropic’s developer-focused product, is generating over $500 million in run-rate revenue, with usage increasing more than tenfold in the last three months, according to the company.
CEO Dario Amodei addressed the challenge of sustaining growth and competition in a memo reported by Wired, noting his discomfort with accepting investments from sovereign wealth funds of dictatorial governments, while acknowledging the practical need to include such investors.
