Anthropic is reportedly gearing up for one of the biggest IPOs in tech history, setting the stage for a public-market race with its rival OpenAI.

According to the Financial Times, the company behind the Claude chatbot has hired the law firm Wilson Sonsini to begin early IPO preparations. A public listing could happen as soon as 2026.

Sources familiar with the talks say Anthropic and OpenAI are now effectively competing to reach the public markets first. Anthropic is also in discussions for a new private funding round that would value the company at more than 300 billion dollars.

Wilson Sonsini, based on the U.S. West Coast, has advised Anthropic since 2022, including on the commercial side of Amazon's multibillion-dollar investments in the company. Several sources say Anthropic has also held informal and early conversations with major investment banks about a potential IPO, though no banks have been selected yet.
