Analysis

4d ago

The market is pricing in an 83% probability of a Starship launch by end-May 2026, with the price surging from 65¢ to 82¢ over the past week, suggesting recent positive sentiment around SpaceX's launch cadence. The extreme 3680% implied yield on the "No" side reflects the sharp cliff risk (score of 5) as we approach the June 1 expiry in just 45 days, though low 24-hour volume of $958 and modest open interest of $33.6k indicate thin liquidity that could amplify price swings. The 182% realized volatility and 1.31 vol ratio suggest this contract has experienced significant price gyrations, likely driven by SpaceX test flight announcements and regulatory updates.

Resolution rules

If SpaceX launches Starship flight test number 12 before June 1, 2026, then the market resolves to Yes.
