Anthropic Secures $13 Billion Series F Round for AI Growth, Safety Research, and International Expansion
Artificial intelligence company Anthropic has secured $13 billion in a Series F funding round, boosting its valuation to an impressive $183 billion. The funds will be allocated towards expanding enterprise adoption, intensifying safety research, and fostering international growth.
The financing was co-led by Iconiq and Fidelity Management & Research Company, with additional backing from a diverse range of institutional investors, venture capital firms, sovereign wealth funds, private equity groups, and asset managers such as Altimeter, Baillie Gifford, BlackRock, Blackstone, Coatue, D1 Capital Partners, Insight Partners, Ontario Teachers’ Pension Plan, Qatar Investment Authority, and others.
In a blog post, Anthropic’s CFO Krishna Rao noted the company’s substantial growth in demand across its customer base. He stated, “This financing underscores investors’ unwavering confidence in our financial performance and their commitment to propelling our unprecedented expansion.”
Anthropic last raised $3.5 billion at a $61.5 billion valuation in March 2025. This latest funding round follows reports suggesting Anthropic was close to closing a deal for between $3 billion and $5 billion, as well as the company’s impressive growth over the course of 2025. The AI startup reported an increase in annual recurring revenue from $1 billion to $5 billion during this period, driven by accelerated API usage and enterprise adoption.
The company currently serves over 300,000 business customers, with its base of large accounts—each contributing over $100,000 in run-rate revenue—having grown nearly sevenfold within the past year.
Anthropic’s Claude Code has also been well-received by developers and is a key factor behind the company’s growth. The firm reported that its vibe-coding product already generates over $500 million in run-rate revenue, with usage surging more than 10x in the last three months.
However, maintaining this growth and competing effectively against rivals like OpenAI, Cursor, and others necessitates additional resources. In a recent memo, CEO Dario Amodei acknowledged the challenge of attracting funding from sovereign wealth funds associated with authoritarian governments. While expressing reservations about such investments, he underscored the difficulty of operating a business by excluding “questionable entities” from investing.
