This market resolves around Jul 6, 2026, once the first seven innings of the game are complete and the result is verifiable from credible public sources.

Resolution happens automatically once the official result is confirmed, and all winning shares are paid out according to their final value.

Several factors can shift prices before this market closes. Lineup announcements, starting pitcher confirmations, and last-minute roster changes often trigger significant moves. Weather conditions at game time—wind speed and direction especially—can favor one team's offensive or pitching style. Injury reports in the days leading up to first pitch may alter expectations for key players. Early game momentum, such as runs scored in the first few innings, will drive sharp price adjustments as traders update their forecasts based on live performance. Breaking news about team strategy or weather delays can also prompt rapid repricing.
