Will Goldman Sachs or any of its underwriting affiliates serve as the lead underwriter in OpenAI's initial public offering?

Kalshi — primary rule

If Goldman Sachs serves as lead-left underwriter on OpenAI's initial public offering in the United States before Jan 1, 2028, then the market resolves to Yes.

Polymarket — resolution criteria

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.
