Goldman Sachs holds a commanding lead in the market for lead-left underwriter on OpenAI’s IPO, driven by its recent selection for the same role on the SpaceX offering and longstanding advisory work with the artificial-intelligence company. Traders have priced in the bank’s dominant position in large technology listings and its ongoing preparation of OpenAI’s confidential S-1 filing, expected in the coming weeks or months ahead of a potential 2026 or 2027 debut. Morgan Stanley ranks a distant second after joint involvement in prospectus drafting and its parallel role on the Anthropic IPO, while smaller shares for other banks reflect limited reported engagement. Key near-term catalysts include any public updates on filing status or lead-bank designation that could shift the current trader consensus.

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.
