Anthropic has raised a $13 billion Series F funding round, achieving a post-money valuation of $183 billion. The company states these new funds will be used to grow its enterprise adoption, deepen its safety research, and support its international expansion.
The investment was co-led by Iconiq, Fidelity Management & Research Company, and Lightspeed Venture Partners. The round also included a wide array of other backers, such as institutional investors, venture capital firms, sovereign wealth funds, private equity, and asset managers. Notable participants include Altimeter, Baillie Gifford, BlackRock, Blackstone, Coatue, D1 Capital Partners, Insight Partners, Ontario Teachers’ Pension Plan, and the Qatar Investment Authority.
Anthropic’s Chief Financial Officer, Krishna Rao, commented on the financing, stating the company is seeing exponential growth in demand across its entire customer base. He said this investment demonstrates extraordinary investor confidence in their financial performance and represents a strong collaboration to fuel their unprecedented growth.
This latest fundraise follows a previous round in March 2025, when Anthropic raised $3.5 billion at a $61.5 billion post-money valuation. Reports had recently indicated the company was nearing a deal to raise between $3 billion and $5 billion at a $170 billion valuation.
The funding comes amid a period of impressive growth for the AI startup. The company reported its annual recurring revenue jumped from $1 billion to $5 billion over the course of 2025, driven by accelerated API usage and enterprise adoption. Anthropic now serves over 300,000 business customers. Its number of large accounts, defined as customers each representing over $100,000 in run-rate revenue, has grown nearly seven times in the past year.
A key driver for this growth is Claude Code, a developer-focused product described as a vibe-coding tool. The company said Claude Code already generates more than $500 million in run-rate revenue, with its usage growing more than tenfold in the last three months.
Maintaining this rapid growth and competing with rivals like OpenAI and Cursor requires significant capital. In a recently reported memo, Anthropic CEO Dario Amodei expressed that he was not thrilled about accepting money from sovereign wealth funds of dictatorial governments. However, he conceded that it is difficult to run a business by excluding what he termed “bad people” from investing.
