This market will resolve according to the bank that serves as the lead underwriter in the initial public offering of OpenAI. 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.Goldman Sachs holds the strongest position as lead underwriter for OpenAI’s upcoming IPO, driven by its recent selection as lead left on the SpaceX offering and dominant share in major tech debuts. OpenAI confidentially filed its S-1 with the SEC in early June 2026 after working primarily with Goldman and Morgan Stanley as top book runners, though the critical “lead left” designation on the prospectus remains undecided amid competition between the two banks. Morgan Stanley’s secondary standing reflects its comparable role in both OpenAI and Anthropic preparations, while lower-probability banks like JPMorgan and others appear involved only in supporting capacities. Trader sentiment aligns with Goldman’s edge in allocation influence and recent execution track record ahead of a potential fall listing for the artificial-intelligence leader.
