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.OpenAI's record $122 billion funding round, closed last week at an $852 billion valuation with backing from Amazon, Nvidia, and SoftBank, has driven trader consensus toward no IPO by December 31, 2026 (64.5% implied probability), underscoring the AI lab's ability to fuel aggressive expansion privately without public market pressures. Ongoing nonprofit restructuring, high cash burn projected through 2030, and CEO Sam Altman's expressed reluctance for public company oversight—coupled with no S-1 filing—reinforce delays despite investor relations hires signaling late-2026 preparations. Trillion-dollar cap outcomes hover below 10%, as private premiums face public market discounts amid AI regulatory scrutiny; a Q4 filing could shift odds rapidly.
