These markets track the performance of the Oakland Athletics and Seattle Mariners in the first five innings of their scheduled game on September 3, 2026. Each market focuses on different run differentials to determine the outcome. The markets remain active even if the game is postponed, closing only after the rescheduled game concludes.
The markets evaluate various run-differential scenarios for the first five innings of the Oakland Athletics vs. Seattle Mariners game scheduled for September 3, 2026. Four distinct outcomes are possible: Seattle winning by more than 2.5 runs, Seattle winning by more than 1.5 runs, Oakland winning by more than 1.5 runs, or Oakland winning by more than 2.5 runs, all measured within the first five innings. If the originally scheduled game is postponed or delayed, all markets stay open and will close after the rescheduled game finishes, provided the rescheduled date occurs within two days of the original. The governing league’s official result determines resolution, and Kalshi disclaims any affiliation with the league or ownership of associated trademarks and branding.
