Anthropic Raises $13 Billion In Funding, Valued At $183 Billion

Anthropic announced on Tuesday that it has completed a Series F funding round, led by investment firm ICONIQ, raising $13 billion. Following the deal, the AI startup is now valued at $185 billion—nearly triple its valuation just six months ago—cementing its status as one of the fastest-growing tech companies in history.

According to Anthropic’s official statement, investors have trusted the company’s performance and product development since the launch of Claude in March 2023. The round was co-led by Fidelity Management & Research Company and Lightspeed Venture Partners, with participation from multiple additional investors who backed Anthropic’s long-term vision.

“At the beginning of 2025, less than two years after launch, Anthropic’s run-rate revenue had grown to approximately $1 billion,” wrote Anthropic. “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.”

In March, the company finished another fundraising deal that valued the company at $61.5 billion—a number almost tripled after this latest agreement. By June, Anthropic had surpassed the $3 billion annualized revenue milestone after focusing on a  business-to-business (B2B) strategy.

Krishna Rao, Chief Financial Officer of Anthropic, explained that Anthropic’s customers—from AI startups to Fortune 500 companies—rely on its AI model “for their most important, mission-critical work.”

In May, Anthropic released its latest AI models, Claude Sonnet 4 and Claude Opus 4, promoting the latter as “the world’s best coding model.” Both gained strong traction in the competitive AI market. The company reported that it now serves more than 300,000 business customers, with the number of large enterprise clients growing seven times in the past year.

“The Series F investment will expand our capacity to meet growing enterprise demand, deepen our safety research, and support international expansion as we continue building reliable, interpretable, and steerable AI systems,” said the company.

Despite recent rumors of an AI financial bubble about to burst in the market, investors continue to bet on Anthropic’s distinctive proposition and its products and services.
