OpenAI Files Confidential IPO Application
OpenAI submitted confidential paperwork to the U.S. securities regulator to pursue a public listing. The company provided few details, saying timing and terms are not yet final, but Reuters reports OpenAI may seek a valuation of up to $1 trillion and that an IPO could occur in September. The move follows a recent filing by competitor Anthropic. OpenAI previously raised capital — reporting $110 billion in investment at an $840 billion valuation — from backers including SoftBank, Amazon and Nvidia; Microsoft has invested about $13 billion since 2019. OpenAI told investors it generated roughly $2 billion in monthly revenue and reported over 900 million weekly active users as of March. Legal risks tied to an investor lawsuit by Elon Musk were reduced after a U.S. jury dismissed the suit in May, which analysts say clears a potential hurdle for the listing.
A confidential IPO filing from a major AI company like OpenAI is significant for capital markets and the AI industry — it could unlock large funding for infrastructure, influence valuations of peer AI and space-tech listings, and serve as a test of investor appetite for AI-related investments.

OpenAI Files Confidential S-1 for IPO
OpenAI filed a confidential draft registration statement with the U.S. Securities and Exchange Commission to pursue an initial public offering, the company announced on 2026-06-08. The move follows rival Anthropic’s recent IPO filing and intensifies a high-profile race to the public markets that also includes SpaceX. OpenAI was last reported valued at $852 billion post‑money and in late March raised $122 billion in a funding round (including $3 billion from retail investors). The company has signalled large future compute and cash‑burn projections (including plans to spend roughly the same amount on computing power in 2028 and an $85 billion projected burn in that year). The filing discloses no share count or price guidance. The announcement comes amid internal governance history and multiple lawsuits involving OpenAI and its leadership.
OpenAI confidentially files for IPO
OpenAI announced it has confidentially submitted a draft S-1 registration statement with the U.S. Securities and Exchange Commission, posting the news on X and saying it has not yet decided on timing. The filing follows rival Anthropic’s confidential IPO filing a week earlier and signals the industry’s largest AI startups are preparing for public scrutiny. OpenAI — the maker of ChatGPT, which reports over 1 billion monthly active users — was last valued at more than $850 billion while Anthropic recently raised capital at an implied $965 billion post‑money valuation. The move has been reported to involve investment banks (including Goldman Sachs and Morgan Stanley) and may include a tender offer to let employees sell shares. The filing comes as OpenAI expands monetization efforts (including ads) and after the company prevailed in litigation involving Elon Musk.
OpenAI Confirms IPO Filing, May Exceed Anthropic
OpenAI confirmed it confidentially submitted a draft S‑1 registration statement to the U.S. Securities and Exchange Commission, signalling that the company is preparing the option of an IPO. The firm said the filing was disclosed in part because it expected the information to leak, but that no final decision or timing for a public offering has been made. The Financial Times reported OpenAI could be valued at more than $1 trillion if it goes public, potentially surpassing recent valuation figures cited for Anthropic (~$965 billion). OpenAI noted some projects remain easier to pursue privately and the company could delay a public share sale despite having completed the confidential filing process.
