Goldman Sachs holds a commanding 70.5% market-implied probability as lead-left underwriter for OpenAI’s IPO due to its prominent role helping prepare the company’s confidential S-1 filing submitted in early June 2026, alongside Morgan Stanley. OpenAI is positioning for a potential late-2026 or 2027 debut at an $850 billion-plus valuation, mirroring Goldman’s recent lead-left assignment on SpaceX’s filing. Traders see Goldman’s track record with large AI-adjacent tech IPOs, deep institutional relationships, and close work with Sam Altman’s team as decisive advantages in the “lead left” contest. Morgan Stanley remains the clear secondary contender at 7%, while other banks trail on limited reported involvement. Key near-term catalysts include any public disclosure of the final underwriting syndicate or updates on listing timing.

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.
