Claude Code Rockets Anthropic to $183B With $13B Series F

Anthropic has raised $13 billion in a Series F financing, bringing its valuation to $183 billion and making it one of the most valuable startups in the world. The round was co-led by Iconiq, Fidelity Management & Research Company, and Lightspeed Venture Partners. Other investors included GIC, Insight Partners, BlackRock, Blackstone, Qatar Investment Authority, and the Ontario Teachers’ Pension Plan.

“We are seeing exponential growth in demand across our entire customer base,” Anthropic Chief Financial Officer Krishna Rao said. “This financing demonstrates investors’ extraordinary confidence in our financial performance and the strength of their collaboration with us to continue fueling our unprecedented growth”.

Anthropic last raised $3.5 billion in March at a $61.5 billion valuation. In less than six months, its worth has nearly tripled. The company said its run-rate revenue has grown from $1 billion at the start of the year to over $5 billion by August. It now counts more than 300,000 business customers, with the number of large accounts nearly seven-fold in the past year.

The surge has been driven in part by Claude Code, Anthropic’s coding assistant launched earlier this year. The company said Claude Code is already generating more than $500 million in run-rate revenue and that usage has grown more than ten-fold in just three months. Independent benchmarks back up its performance. In July, Anthropic disclosed that Claude Opus 4.1, the model powering Claude Code, achieved a 74.5% score on the SWE-bench Verified benchmark, topping OpenAI’s o3 and Google’s Gemini 2.5 Pro.
