Anthropic reportedly plans $10 billion raise at $350 billion valuation

Anthropic is preparing to raise a new $10 billion funding round at a valuation of $350 billion, according to reports. The fundraising effort, first reported by The Wall Street Journal and confirmed by a person familiar with the matter, would nearly double the company’s valuation from its most recent round just three months ago. If completed as expected, the deal would mark one of the largest private fundraising rounds ever for an artificial intelligence company.

The Claude chatbot maker last raised $13 billion in a Series F round at a $183 billion valuation, underscoring the rapid pace at which its value has increased. Earlier in March, Anthropic secured $3.5 billion at a valuation of $61.5 billion, showing how quickly investor interest has accelerated alongside growing demand for advanced AI systems. The proposed new round would continue that momentum as competition among major AI developers intensifies.

According to people familiar with the deal, the latest financing is expected to be led by Coatue Management and GIC, Singapore’s sovereign wealth fund. The round is expected to close in the coming weeks, though the final amount raised could still change as negotiations continue. Anthropic declined to comment on the reported plans.

This funding would be separate from a previously announced $15 billion commitment involving Nvidia and Microsoft. That arrangement, described as a circular deal, would see Anthropic purchase up to $30 billion in computing capacity from Microsoft’s Azure cloud platform, powered by Nvidia’s AI chips. The structure highlights how closely capital investment and access to computing resources have become linked in the AI sector.

The new capital comes as Anthropic continues to attract developers with Claude Code, a tool designed to automate software development tasks using its Claude Opus 4.5 model. The company has positioned itself as a strong rival to OpenAI, which is also reportedly in talks to raise up to $100 billion at a valuation as high as $830 billion. Both companies are said to be exploring potential initial public offerings later this year, signaling a new phase for the rapidly expanding AI industry.
