SpaceX's completed June 2026 IPO at a $1.77 trillion valuation, which surged above $2 trillion on debut amid strong Starlink revenue and xAI integration, underpins the 57.9% market-implied odds favoring it over OpenAI. OpenAI's confidential filing earlier this year has given way to CEO Sam Altman's September 12 confirmation that no 2026 listing will occur, citing AI safety and alignment priorities, with private valuations hovering near $850 billion and a $1 trillion target eyed for 2027. Traders view SpaceX's audited financials, established public trading, and infrastructure moat as durable advantages, while OpenAI faces execution and regulatory hurdles that could compress its eventual IPO cap. Upcoming catalysts include any OpenAI safety announcements or revised timelines that might narrow the gap.

- Neither IPO occurs by December 31, 2027, 11:59 PM ET.
- Both SpaceX and OpenAI complete an IPO within this market's timeframe, and their IPO closing market capitalizations are exactly equal.
- Both companies become unable to complete an IPO, including due to acquisition, merger, or absorption by an entity that is already publicly traded.
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 the respective companies’ 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.
