Anthropic is in talks to raise about $10 billion in fresh funding at a $350 billion valuation, according to The Wall Street Journal, with Reuters also reporting the same headline terms.
Per the report, the round is expected to be led by Coatue Management and GIC (Singapore’s sovereign wealth fund). People familiar with the discussions told the WSJ the financing could be completed within weeks, though the total amount and final terms may still shift.
If completed at the mooted valuation, the fundraise would mark another sharp step-up for the Claude developer after a rapid run of large financings in 2025. Anthropic’s most recent round was a $13 billion Series F completed in September 2025, which the company said valued it at $183 billion post-money.
Earlier in the year, Anthropic announced a $3.5 billion Series E at a $61.5 billion post-money valuation.
Strategic partnership
The reported fundraising would also be separate from the strategic partnership announced in November 2025 involving Microsoft and Nvidia. In that arrangement, Microsoft and Nvidia said they would invest a combined $15 billion in Anthropic, while Anthropic committed to purchase $30 billion of Microsoft Azure compute capacity “powered by Nvidia” systems (with an option to contract additional capacity up to 1 gigawatt).
The new capital raise comes as investor attention remains fixed on developer-facing tooling and enterprise adoption. Reuters noted Anthropic’s Claude models are “particularly favored by developers for coding tasks,” and reported the company has been preparing for a possible IPO as early as 2026.
The reported deal would land against a broader wave of mega-round talk across top AI labs. In December, the WSJ and TechCrunch reported OpenAI was in early discussions to raise up to $100 billion at a valuation of up to $830 billion.
