SpaceX’s June 2026 IPO filing targeting a $1.75–2 trillion valuation anchors the 90.3% market-implied probability that its closing market cap will exceed OpenAI’s. This positioning reflects Starlink’s rapid scaling to over 10 million subscribers, combined with reusable Falcon and Starship launch revenue, NASA contracts, and recent integration of xAI orbital data-center capabilities that together produced $18 billion in 2025 revenue. OpenAI’s latest $852 billion post-money private valuation and Q4 2026 timeline introduce greater uncertainty due to continued operating losses and a projected profitability horizon of 2030. While Starship development delays or broad equity-market volatility could narrow the gap, current model consensus and historical launch success rates support SpaceX’s earlier fundamentals and higher expected IPO size.

This market will resolve to “OpenAI” if the official closing price for OpenAI’s market capitalization on its first trading day is above the official closing price for SpaceX’s market capitalization on its first trading day.
This market will resolve to the company that completes an Initial Public Offering (IPO) by December 31, 2027, 11:59 PM ET, if the other company does not complete an IPO within the market timeframe. This market will resolve to the IPOed company as soon as it becomes impossible for the other company to complete an IPO within the market timeframe, including due to acquisition, merger, or absorption by an entity that is already publicly traded.
This market will resolve 50-50 if:
- 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.
