Description

This market tracks whether SpaceX will conduct its fifteenth Starship flight test within specific timeframes. The outcome depends on whether the launch occurs after the market issuance and before the defined deadline, as confirmed by SpaceX. Each market covers a different end date, allowing participants to speculate on the timing of the launch.

Kalshi

The event determines whether SpaceX will conduct its fifteenth Starship flight test within any of the specified timeframes ending on October 16, 2026, October 30, 2026, November 13, 2026, November 27, 2026, or December 11, 2026. For all markets, a successful resolution requires that the launch occurs after the market issuance date but before the respective deadline. The decisive factor is the calendar date of liftoff at the launch site, as officially confirmed by SpaceX. If the fifteenth flight test occurs within any of these windows, all corresponding markets resolve positively. The rules ensure consistent evaluation across all markets by using the same verification standard—public confirmation from SpaceX of the exact launch date and local timezone.

Several key signals and events could significantly impact this market. Any delays or setbacks in SpaceX's launch schedule, such as technical issues discovered during testing or unfavorable weather conditions, would likely decrease the probability of a successful launch and lower prices. Conversely, positive developments like successful static fire tests or favorable regulatory approvals could boost confidence and increase prices. Major announcements from SpaceX regarding launch preparations, or changes to the launch vehicle's configuration, could also trigger substantial market movement.
