The game will track how many runs are scored specifically in the ninth inning by both teams. If at least one run is scored in that inning, the outcome will be considered successful.
Markets resolve to Yes if the Oakland Athletics and Tampa Bay collectively score more than 0.5 runs in the 9th inning of their professional baseball game scheduled for September 15, 2026. Only runs scored during the 9th inning count; if the game is called early before the inning completes, the market resolves to a Fair Price, regardless of whether the home team bats in the bottom of the inning.
