• Early June: Anthropic moves first
• June 8: OpenAI confirms its S-1
• Competing narratives: race or routine financing?
• Investor scrutiny and market test

OpenAI Confidentially Files for Initial Public Offering OpenAI has quietly taken a major step toward Wall Street, even as it insists it is in no rush to become a public company. Its confidential filing also sharpens a high-stakes race with rival Anthropic over who will define the next era of generative AI in the public markets.

§Early June: Anthropic moves first

On June 1, Anthropic confidentially submitted its own IPO paperwork, instantly positioning itself as the leading pure-play generative AI candidate for public investors. As of its most recent fundraise, Anthropic was labeled “the world’s most valuable startup,” with a post-money valuation of about $965 billion, edging past OpenAI’s $852 billion.

§June 8: OpenAI confirms its S-1

In the early hours of June 8, OpenAI published a short statement disclosing that it had “recently submitted a confidential S-1,” adding that it expected the news to leak and therefore was “just announcing it.” The company stressed that it has “not decided on timing yet; it may be a while because there are things we want to do that are likely easier as a private company,” framing the move as keeping options open rather than a firm listing plan.

Later that day, tech and business outlets confirmed that OpenAI had confidentially filed a draft registration with the U.S. Securities and Exchange Commission, marking “the first official step toward a blockbuster IPO” and “a little more than a week after its main rival, Anthropic, also filed to go public.” Axios reported that the filing “gives it the option to tap public markets” and that a listing “could come as soon as this fall,” with Goldman Sachs and Morgan Stanley involved.

§Competing narratives: race or routine financing?

Coverage has framed the moment as a direct race for capital. TechCrunch described OpenAI as having “filed confidentially for an initial public offering, … ramping up the race between the two AI firms.” The Verge called it “one of the most highly anticipated public offerings in history,” noting that Anthropic’s valuation now slightly surpasses OpenAI’s.

OpenAI, by contrast, has tried to downplay any IPO sprint. In a blog-aligned framing, going public is described as “a complicated set of tradeoffs” that simply “gives us the option to go public sooner if that ends up being best.” CEO Sam Altman has similarly cast IPO timing as secondary to “a race to deliver the best technology and build the best business.”

§Investor scrutiny and market test

Reports indicate internal tensions over the fast track, with some executives, including CFO Sarah Friar, said to be less enthusiastic amid missed revenue and user-growth targets and enormous compute spending commitments. An IPO would provide liquidity and funding for that infrastructure but also force detailed public disclosures and expose the company to market volatility.

Analysts say the twin IPOs of OpenAI and Anthropic will introduce “pure-play Gen AI giants to public markets for the first time,” serving as a major test of Wall Street’s appetite for the technology. With both firms valued near $1 trillion and SpaceX’s own mega-listing imminent, 2026 is shaping up as a decisive year not just for AI innovation, but for how investors price its long-term promise and risks.
