Overview

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.

However, CFO Sarah Friar has internally cautioned against the aggressive timeline, citing $121 billion in projected 2028 compute costs, 2026 revenue estimates around $25 billion against $19 billion cash burn, and a lofty 28x forward multiple amid competition from Anthropic. Key catalysts include a potential Q3 S-1 filing revealing audited financials and roadshows, which could validate or pressure the closing market cap amid volatile AI sector sentiment and regulatory scrutiny.",
