For the Kansas City versus Boston game, the 9th inning will be watched closely to see if more than half a run is scored. This final inning often decides the outcome of baseball games.
Markets resolve to Yes if Kansas City and Boston collectively score more than 0.5 or more than 1.5 runs in the 9th inning of the game scheduled for Sep 12, 2026. Only runs scored during the 9th inning count, even if the home team does not bat, unless the inning is incomplete due to an early game cancellation; if the game is called before completion of the 9th inning, the market resolves to a Fair Price.
