This market asks whether OpenAI’s stock market debut, if and when it happens, will finish its first trading day with a company valuation above $1.4 trillion. That makes it a threshold question about both the size of any eventual IPO and how investors price the shares on day one.
The event is OpenAI’s first day of public trading, with resolution based on the official closing price and the listed share count used to calculate market capitalization. If the company never completes an IPO by December 31, 2027, the market resolves to No. Because the title names a specific valuation threshold, the key issue is not just whether OpenAI goes public, but whether its first official closing valuation ends above $1.4T.
OpenAI is one of the most closely watched private technology companies, and any IPO would be a major capital markets event. The uncertainty here comes from two layers: whether an IPO happens at all before the deadline, and, if it does, whether the first-day close values the company above the stated cutoff. Readers are effectively watching for disagreement about demand for the shares, the size of the offering, and the market’s initial view of OpenAI’s business prospects.
The biggest price-moving developments are concrete IPO milestones: confirmation that OpenAI has filed, priced, and launched an offering, or conversely that plans are delayed or abandoned. Any details about the number of shares outstanding, the offering price range, or the expected valuation would matter because this market is tied directly to the first official closing market cap. If the company’s debut is postponed past the deadline, that would push the outcome toward No under the rules.
The current market price implies roughly a 35% chance for the leading outcome, based on live Polymarket pricing. That number is not a prediction from PredictionNinja and it is not a guarantee; it is the current crowd-priced view of the market and can change quickly when new information appears.

View marketThe source of truth is the primary exchange’s official listing page, with another reliable source only if the relevant figure is not shown there. Readers should verify the exact first trading day, the official closing price, and the share count used to compute market capitalization, since those are the rule-based inputs. The resolution rules also cover disruptions: if trading is interrupted or shortened, the official closing price of the abbreviated session is used, and if no official close is published that day, the next trading day with an official close becomes the reference point.

This market is currently listed with an end date of Dec 31, 2027. Market timelines can change if the underlying event is postponed, rescheduled, or resolved early.
This market will resolve to “Yes” if the official closing price for OpenAI's market capitalization on its first trading day is above the listed value. Otherwise, it will resolve to “No”. If no IPO occurs by December 31, 2027, 11:59 PM ET, this market will resolve to “No”. Market capitalization is defined as the total number of outstanding shares multiplied by the closing share price on the first trading day. 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.
