Anthropic has confidentially submitted a draft registration statement to the US Securities and Exchange Commission for a proposed initial public offering, putting the Claude maker ahead of OpenAI in the race to bring a major frontier AI lab to public markets.

The filing gives Anthropic the option to go public after the SEC completes its review. The company has not determined the number of shares to be offered or the price range, and the proposed IPO remains subject to market conditions and other factors.

The move comes as OpenAI has also been preparing for a potential IPO, with reports indicating the ChatGPT maker has been working with bankers on a filing that could come in the coming days or weeks. Anthropic’s announcement makes it the first of the two companies to publicly confirm a confidential IPO submission.

Anthropic’s filing follows a $65 billion Series H funding round that valued the company at $965 billion post money, placing it near the $1 trillion mark as investor demand for frontier AI companies continues to accelerate. The round was led by Altimeter Capital, Dragoneer, Greenoaks, and Sequoia Capital.

The company also recently released Claude Opus 4.8, its latest Opus class model, as it continues expanding Claude’s role across coding, agentic workflows, reasoning, and enterprise software tasks. Anthropic has also said its Mythos class models are expected to reach customers in the coming weeks after additional cybersecurity safeguards.

A public listing would give investors a closer look at Anthropic’s revenue growth, infrastructure costs, and competitive position against OpenAI, Google, and other AI developers. It would also mark a major test for public market demand around frontier AI companies after a private funding boom that has pushed valuations toward historic levels.
