Analysis

5d ago

The 66¢ price implies a 66% probability SpaceX reaches a $1.8T valuation at IPO, but the asymmetric implied yields (30.2% for Yes vs. 113.7% for No) suggest the market is pricing in substantial skepticism about execution risk despite the bullish surface probability. With $4.99M open interest and only $319.8K in 24-hour volume, liquidity is thin relative to OI, and the extreme 246% realized volatility combined with a 4.55 vol ratio indicates this market has experienced sharp swings—the modest 2¢ decline over seven days masks underlying instability. The 623-day timeframe and neutral regime score suggest traders are genuinely uncertain about both IPO timing and valuation, making this a high-uncertainty event bet rather than a directional conviction play.

Resolution rules

This market will resolve to “Yes” if the official closing price for SpaceX’s market capitalization on its first trading day is above the value specified in the title. 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 SpaceX’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.
