Goldman Sachs holds a commanding 75.5% market-implied probability as lead underwriter for OpenAI's IPO due to its recent capture of the "lead left" position on the SpaceX offering and established dominance in high-profile technology listings. Reports from June 2026 confirm that both Goldman and Morgan Stanley were selected as top book runners for the confidential filing OpenAI submitted that month, yet Goldman’s stronger recent momentum and broader tech IPO market share have tilted trader consensus heavily in its favor. Morgan Stanley’s 22.5% odds reflect its role as a close contender, while smaller allocations to other banks highlight limited expectations for their involvement. With OpenAI’s potential debut eyed for late 2026 or 2027 amid AI sector volatility, the next catalyst will likely be any public disclosure clarifying the lead left designation on the S-1.

If no IPO occurs by December 31, 2027, 11:59 PM ET, or OpenAI completes an initial public offering without a designated lead underwriter, this market will resolve to “Other.”
If multiple banks are identified as lead underwriters, this market will resolve according to the primary lead underwriter. If the hierarchy between them is unclear, this market will resolve once it is conclusively evident which bank is the primary lead underwriter, for example, through the order in which the banks are listed in the underwriting section of OpenAI's final initial public offering prospectus, once released.
The primary resolution source for this market will be official disclosures from OpenAI. A consensus of credible reporting may also be used.
