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, 2027, 11:59 PM ET, the market will resolve to "No IPO by December 31, 2027". 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.Trader consensus on Polymarket prices a potential OpenAI IPO closing market cap exceeding $1.5 trillion at 42.4% implied probability, reflecting the firm's explosive growth trajectory underscored by its March 31, 2026, funding round that raised $122 billion at an $852 billion post-money valuation—more than doubling prior marks and signaling robust revenue run-rate above $25 billion annualized. Supporting this are early groundwork for a Q4 2026 listing, including finance team hires and informal banker talks to preempt rivals like Anthropic. However, 21.5% odds on no IPO by December 31, 2027, capture recent headwinds: WSJ reports of Q1 revenue/user misses, CFO Sarah Friar's push to delay amid $600 billion compute commitments, and competitive pressures. Key catalysts include S-1 filings or regulatory updates ahead of year-end.
