Goldman Sachs holds a commanding lead in trader-implied odds for serving as lead underwriter on OpenAI’s IPO, driven by its recent selection as lead-left bookrunner for the SpaceX offering and longstanding dominance in large-scale technology listings. OpenAI confidentially filed its S-1 in June 2026 after working closely with both Goldman and Morgan Stanley on prospectus drafting, yet reports highlight Goldman’s edge in securing the prized top position amid a crowded field of AI debuts that also includes rival Anthropic. Morgan Stanley remains the primary challenger, with lower-probability banks viewed mainly as potential syndicate participants. Key near-term catalysts include any public disclosure of underwriting hierarchy and confirmation of a 2026 versus 2027 launch window, as market volatility has already prompted speculation around timing adjustments.

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.
