Anthropic Raises $13bn in Series F Funding, Valued at $183bn

Anthropic has raised $13bn in a Series F funding round, valuing the company at $183bn. The company's run-rate revenue has grown exponentially, surpassing $5bn in August. Anthropic is a major challenger to OpenAI's dominance in AI chat interfaces and large language models, with a focus on financial analysis services and coding functionality. The funding round was led by ICONIQ and co-led by Fidelity Management & Research Company and Lightspeed Venture Partners.

Anthropic, a leading AI safety and research company, has secured $13 billion in a Series F funding round, pushing its valuation to $183 billion. The financing was led by ICONIQ Capital, with co-leads from Fidelity Management & Research and Lightspeed Venture Partners. Additional investors included Altimeter, Baillie Gifford, affiliated funds of BlackRock, Blackstone, Coatue, D1 Capital Partners, General Atlantic, General Catalyst, GIC, Growth Equity at Goldman Sachs Alternatives, Insight Partners, Jane Street, Ontario Teachers' Pension Plan, Qatar Investment Authority, TPG, T. Rowe Price Associates, Inc., T. Rowe Price Investment Management, Inc., WCM Investment Management, and XN.

The investment reflects Anthropic’s continued momentum and reinforces its position as a leading intelligence platform for enterprises, developers, and power users. "From Fortune 500 companies to AI-native startups, our customers rely on Anthropic’s frontier models and platform products for their most important, mission-critical work," said Krishna Rao, Chief Financial Officer of Anthropic. "We are seeing exponential growth in demand across our entire customer base. 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 has seen rapid growth since the launch of Claude in March 2023. At the beginning of 2025, less than two years after launch, Anthropic’s run-rate revenue had grown to approximately $1 billion. By August 2025, just eight months later, our run-rate revenue reached over $5 billion—making Anthropic one of the fastest-growing technology companies in history.

The Series F investment will expand Anthropic’s capacity to meet growing enterprise demand, deepen its safety research, and support international expansion as it continues building reliable, interpretable, and steerable AI systems. "Anthropic is on an exceptional trajectory, combining research excellence, technological leadership, and relentless focus on customers," said Divesh Makan, Partner at ICONIQ. "Enterprise leaders tell us what we’re seeing firsthand—Claude is reliable, built on a trustworthy foundation, and guided by leaders truly focused on the long term."

Anthropic's valuation has been on a steep climb since it announced its AI assistant Claude in March 2023. The Amazon-backed startup was founded by former OpenAI research executives, including its CEO Dario Amodei. OpenAI and Anthropic are fierce competitors in the AI market. As of August, Anthropic said its run-rate revenue has reached more than $5 billion, up from roughly $1 billion at the beginning of the year. Anthropic serves more than 300,000 business customers.
