Anthropic in talks to raise $10B at $350B valuation as AI frenzy accelerates

Anthropic is back in the spotlight, and this time the numbers are staggering.

The Claude chatbot maker is in talks to raise roughly $10 billion in a new funding round that would value the company at around $350 billion, according to two sources cited by Reuters. If completed, the deal would mark a sharp jump from its last valuation just four months ago and place Anthropic among the most valuable private companies globally.

The talks, first reported by the Wall Street Journal, point to Singapore’s sovereign wealth fund GIC and investment firm Coatue Management as potential leaders of the round. The Journal reported that the financing could close within weeks, though the final size and structure remain in flux. Anthropic declined to comment.

“Anthropic, the developer of the chatbot Claude, plans to raise $10 billion at a valuation of $350 billion before the new investment, according to people familiar with the matter, nearly doubling its valuation from four months ago,” the Wall Street Journal reported.

The fundraising chatter arrives alongside growing speculation about a public debut. Last month, the Financial Times reported that Anthropic had begun laying the groundwork for one of the largest tech IPOs of the next cycle, with informal discussions suggesting a listing could occur as early as next year. The company has hired law firm Wilson Sonsini to prepare for that possibility, according to the FT, though a spokesperson previously said no final decision had been made.

Founded in 2021 by former OpenAI staff, Anthropic has built a strong reputation with its Claude models, especially among developers working on coding and enterprise use cases. That focus has translated into revenue momentum. Reuters reported in October that the company expects to more than double, and possibly nearly triple, its annualized revenue run rate this year as enterprise adoption continues to climb.

Strategic backing has played a central role in Anthropic’s rise. The startup counts Google and Amazon among its major supporters, with both companies seeking long-term access to its models. Separate FT reporting indicates that Microsoft and Nvidia could be involved in future private commitments that push the company’s valuation well above $300 billion.

At the center of it all is co-founder and CEO Dario Amodei, who has steered Anthropic into a rare group of AI labs capable of training trillion-parameter systems using their own data center infrastructure. Since its early days, the company has pulled in tens of billions of dollars from partners eager to secure access to large-scale models, a dynamic that continues to reshape the balance of power in AI.

The scale of the proposed raise reflects a broader surge in spending tied to enterprise AI adoption. It has fueled soaring valuations across the sector, even as investors quietly debate how much runway remains before enthusiasm cools. For Anthropic, the talks signal confidence that demand for advanced AI systems is still climbing, and that the window for mega-rounds has not yet closed.
