The artificial intelligence (AI) startup doubled the amount it was in talks to raise after seeing a high level of demand from investors, according to the report.
One investor told the FT that Anthropic has seen as much as six times the interest it originally expected. Other sources said the company will lock in as much as $15 billion as early as Tuesday and the remainder of the raise within weeks, per the report.
These figures are separate from the $15 billion that Microsoft and Nvidia have committed to invest in Anthropic, according to the report.
Anthropic did not immediately reply to PYMNTS’ request for comment.
The company said in September 2025 that it raised $13 billion in a Series F funding round that valued it at $183 billion.

It said at the time that its run-rate revenue leapt from about $1 billion at the beginning of 2025 to over $5 billionin August, and that its Claude Code tool for developers was generating run-rate revenue of over $500 million. The company added that it was serving more than 300,000 business accounts and that over the previous year, it increased by seven times the number of customers that each represent run-rate revenue of over $100,000.
“We are seeing exponential growth in demand across our entire customer base,” Anthropic Chief Financial Officer Krishna Rao said in a September 2025 press release. “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 CEO Dario Amodei said in December 2025 that the future of AI’s economic value lies in a relentless, technically rigorous focus on enterprise needs and disciplined, long-term infrastructure planning.
While the company’s competitors sprint for mass-market adoption, Amodei positioned Anthropic as having a “privileged position” to methodically “keep growing and just keep developing our models,” deliberately rooting its value in the stability and consistency required by high-stakes business users.
On Jan. 9, financial services provider Allianz said it planned to deploy AI throughout its insurance business around the world with the help of Anthropic.
On Jan. 14, it was reported that Microsoft has become one of Anthropic’s top customers and is on track to spend around $500 million a year to use Anthropic’s AI in Microsoft products.
