Goldman Sachs holds a commanding 70.5% implied probability in the Polymarket for lead-left underwriter on OpenAI’s IPO, driven by its recent selection for the same role on SpaceX’s offering and established advisory work with OpenAI and rival Anthropic. Both AI labs have engaged Goldman and Morgan Stanley as top bookrunners ahead of anticipated 2026 debuts targeting valuations exceeding $850 billion, with OpenAI’s confidential S-1 filing submitted in early June accelerating preparations for a potential September launch. Traders weigh Goldman’s execution track record in large-scale technology listings against Morgan Stanley’s competitive positioning, while smaller probabilities for UBS, JPMorgan, and others reflect limited recent involvement in these AI-specific mandates. Key near-term catalysts include further prospectus details and any shifts in bookrunner hierarchy.

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.
