This market will resolve based on OpenAI's market capitalization at the closing price on its first day of trading. If no IPO occurs by December 31, 2026, 11:59 PM ET, the market will resolve to "No IPO by December 31, 2026". Market capitalization expresses the monetary value of a company’s outstanding shares, stated in its pricing currency. It is calculated as the number of shares outstanding multiplied by the closing share price on the first trading day. If the relevant value falls exactly between two brackets, then this market will resolve to the higher range bracket. Resolution will be based on the primary exchange’s official listing page. In the event that the relevant figure is not displayed, another reliable source will be used. In the event of an interruption in the course of the normal trading session on OpenAI’s first day of trading (e.g., a circuit breaker or half-day), the market will resolve according to the official closing price of the abbreviated session. If no such official closing price is published, the market will resolve according to the next trading day on which an official closing price is published, treating that as the first day of trading for purposes of this market.Recent confidential S-1 filing positions the "no IPO by December 31, 2026" outcome as the market leader at 54.5% implied probability. OpenAI's June 8 announcement and statements that timing "may be a while" and growth priorities outweigh listing reflect caution, despite Goldman Sachs and Morgan Stanley advising. March 2026's $122 billion round at an $852 billion valuation and ongoing nonprofit restructuring add execution hurdles that could push a full debut into 2027. Trader consensus on higher valuation buckets (750B–1T and above totaling over 40%) assumes successful timing and strong AI demand, yet acknowledges typical delays in large tech listings and profitability pressures.
