Goldman Sachs leads trader sentiment at 75.5% implied probability for serving as lead-left underwriter on OpenAI's IPO due to its prominent role in the company's May 2026 confidential S-1 filing alongside Morgan Stanley. Recent reporting highlights both banks preparing isolated deal teams amid simultaneous AI IPO mandates, with Goldman gaining an edge from prior high-profile tech mandates and stock gains tied to the news. OpenAI's strong revenue growth from ChatGPT and enterprise API usage supports a potential late-2026 or 2027 listing at massive scale, though timing remains fluid. Morgan Stanley holds 22.5% as the main challenger, while smaller shares reflect limited recent involvement from other banks.

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.
