Anthropic Aims to Nearly Double Valuation in New Funding Round

Anthropic reportedly aims to raise $10 billion in a funding round that is separate from a partnership in which Nvidia and Microsoft have pledged to invest a combined total of $15 billion in the artificial intelligence (AI) startup.

The new funding round would value Anthropic at $350 billion, which is nearly double the valuation it achieved in a September 2025 round, the Wall Street Journal reported Wednesday (Jan. 7), citing unnamed sources.

The round is expected to close within weeks, though the details could change, according to the report.

Anthropic did not immediately reply to PYMNTS’ request for comment.

The company announced in September that it was valued at $183 billion in a Series F funding round in which it raised $13 billion.

When announcing that round, Anthropic said its run-rate revenue had leapt from about $1 billion at the beginning of 2025 to over $5 billion in August, its Claude Code tool for developers generated run-rate revenue of over $500 million, and its number of business accounts had topped 300,000.

“We are seeing exponential growth in demand across our entire customer base,” Anthropic Chief Financial Officer Krishna Rao said in a Sept. 2 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, Microsoft and Nvidia announced their partnership in November, saying that Microsoft pledged to invest up to $5 billion in Anthropic, Nvidia pledged to invest up to $10 billion, and Anthropic agreed to purchase $30 billion of Nvidia-powered Microsoft Azure compute capacity and contract additional compute capacity up to one gigawatt.

“We are increasingly going to be customers of each other,” Microsoft CEO Satya Nadella said in a video statement accompanying the announcement, in which he was joined by Jensen Huang and Dario Amodei, his counterparts from Nvidia and Anthropic.

It was reported Dec. 28 that Silicon Valley’s AI startups raised a record $150 billion in 2025, with companies like Anthropic and OpenAI attracting strong interest from investors. The year’s funding levels surpassed the previous record of $92 billion set in 2021.
