Goldman Sachs holds an 86% market-implied probability as lead underwriter for OpenAI’s IPO due to its recent lead-left role on the SpaceX listing and stronger positioning in major artificial-intelligence and technology debuts. OpenAI confidentially filed its S-1 in June 2026 alongside Anthropic, with Goldman and Morgan Stanley named as primary bookrunners, though the decisive “lead left” designation on the prospectus remains open amid competition between the two banks. Morgan Stanley’s 12.5% odds reflect its comparable involvement in both OpenAI and Anthropic preparations, while other institutions appear limited to supporting roles. The potential 2027 timeline shift, driven by market volatility and valuation targets near $1 trillion, has not altered the current syndicate hierarchy according to trader consensus.

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.
