Anthropic has taken its first formal step toward becoming a public company, announcing Monday that it confidentially submitted a draft S-1 registration statement to the U.S. Securities and Exchange Commission for a proposed initial public offering.
The filing gives the Claude developer the option to move forward with an IPO after the SEC completes its review, although the company said any offering remains subject to market conditions and other factors.
The announcement comes days after Anthropic raised $65 billion in Series H funding at a reported $965 billion valuation, making it one of the world's most valuable private technology companies.
“Earlier this month, our run-rate revenue crossed $47 billion,” Anthropic wrote on X at the time. “This growth has been driven by organizations across many industries deploying Claude in their core operations, and by a growing number of people using it for their everyday work.”
The IPO announcement follows several high-profile developments from Anthropic, including the launch of Opus 4.8, and the news that its controversial Claude Mythos model may soon be available to the public.
Anthropic said it has not yet determined the number of shares it may offer or a potential price range.
The filing comes as leading AI companies prepare to go public. In May, the Wall Street Journal reported that OpenAI was preparing for its own confidential IPO filing, targeting a September listing with Goldman Sachs and Morgan Stanley leading the offering.
At the same time, rival AI developer xAI, now a part of SpaceX, filed its own IPO seeking a historic $1.75 trillion valuation, showing billions in spending on artificial intelligence infrastructure and Starship development. The IPO would preserve owner and CEO Elon Musk's control through a dual-class share structure.
Anthropic did not immediately respond to a request for comment by Decrypt.
Users on Myriad—a prediction market platform operated by Decrypt's parent company, Dastan—now believe that Anthropic will beat OpenAI to a public offering, giving the Claude maker 58% odds as of this writing. Those odds flipped following the Monday announcement, with OpenAI previously leading at 68%.
