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 recent confidential S-1 filing with the SEC on June 8, 2026, is the primary catalyst shaping market-implied odds.** Traders assign a 53.5% probability to no IPO by year-end 2026 because the company stated it “has not decided on timing yet” and prefers remaining private for certain initiatives, consistent with typical 60- to 90-day SEC review plus roadshow timelines that could push listing into 2027. The 21.1% probability on a $1T–1.25T close reflects OpenAI’s $852 billion post-money valuation from its March 2026 round and underwriter targets near $1 trillion, tempered by ongoing heavy losses and regulatory scrutiny. Competitive AI IPO activity, including Anthropic’s filing, and strong investor demand for large language model leaders support the smaller 13.9% chance of $1.5T+, while lower buckets capture downside risk from execution delays or valuation compression.
