OpenAI Nears Confidential IPO Filing, Targeting Trillion-Dollar Valuation
5/23/2026, 8:24:42 PM
Impending Confidential Filing and Valuation
OpenAI is set to file a confidential registration statement with the SEC, a step that could precede a public offering as early as September. The company’s last private round valued it at $852 billion; analysts anticipate a potential $1 trillion market cap for the IPO.
Structural Background
Founded as a non-profit, OpenAI reorganized in October 2025 into a for-profit public-benefit corporation, preserving a mission-oriented charter while permitting equity financing and shareholder participation.
Ownership and Stakeholder Stakes
Microsoft holds roughly 27 % of the new entity, the OpenAI Foundation 26 %, and the balance is owned by employees and other investors. President Greg Brockman’s stake is valued near $30 billion, potentially $35 billion at a $1 trillion valuation; Sam Altman’s equity remains undisclosed.
Financial Snapshot
OpenAI posted about $6 billion in first-quarter revenue, driven by Codex and ChatGPT subscriptions. The S-1 is expected to reveal cash burn on model training, compute infrastructure, and high-cost talent, as well as the cost per token served.
Official Statement from Leadership
The CEO told staff that filing for an IPO is separate from being ready to list and that the company will not go public until it deems itself prepared.
Criticism and Risks
Analysts highlight OpenAI’s ongoing losses, high compute costs per AI response, and the difficulty of achieving sustainable margins. The prospectus is expected to address competition, customer concentration, existential AI threats, potential misuse, and pending lawsuits over psychological harms.
Conflicting Reports and Gaps
One source says the confidential filing could occur today, while another suggests the S-1 may not appear for weeks or months. Valuation estimates range from $852 billion to $1 trillion, and Altman’s equity details remain absent.

What’s Next
If the filing proceeds this week, the SEC will review the draft before the S-1 is made public at least 15 days before a road show, which typically precedes an IPO by one to two weeks. A September debut would set a benchmark for other AI listings, including Anthropic, and could shape valuation expectations for related assets such as SoftBank’s holdings.
