AI giant Anthropic announced a Series F $13bn capital raise this week, valuing the company at $183bn as the company sees an explosion in its run-rate revenue.
The funding round means Anthropic has a higher company valuation than all but three FTSE 100 companies.
Having entered 2025 with run-rate revenue of $1bn, the company enjoyed one of the fastest periods of growth of any tech company in history as the firm launched new features and improved models. Anthropic’s run-rate revenue surpassed $5bn in August.
Anthropic is one of the biggest challengers to OpenAI’s dominance of AI chat interfaces and large language models. The company has launched a string of AI innovations in recent months, including its coding functionality and financial analysis services.
“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.”
The funding round was led by ICONIQ and co-led by Fidelity Management & Research Company and Lightspeed Venture Partners. Other investors include Altimeter, Baillie Gifford, and affiliated funds of BlackRock, Blackstone, Coatue, D1 Capital Partners, General Atlantic, and General Catalyst.
“Anthropic is on an exceptional trajectory, combining research excellence, technological leadership, and relentless focus on customers. We’re honored to partner with Dario and the team, and our lead investment in their Series F reflects our belief in their values and their ability to shape the future of responsible AI,” 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.”
