Recent preparations to confidentially file IPO paperwork as soon as late May 2026, targeting a potential September listing, have kept the probability of an IPO by year-end near 73% while supporting elevated valuation scenarios above $1 trillion. OpenAI’s latest $122 billion funding round at an $852 billion post-money valuation underscores strong investor appetite for its large language model advancements and infrastructure ambitions, though ongoing multibillion-dollar losses and the need for trillions in AI compute spending introduce execution risks that could delay the offering or moderate the final market cap. Competitive pressure from rivals like Anthropic and the recent SpaceX filing adds urgency, yet fluid timelines and market volatility around artificial intelligence adoption remain key swing factors for traders assessing outcomes clustered between no IPO and a 1.5 trillion-plus debut.

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 preparations to confidentially file IPO paperwork as soon as late May 2026, targeting a potential September listing, have kept the probability of an IPO by year-end near 73% while supporting elevated valuation scenarios above $1 trillion.
