For the Arizona-Houston matchup, participants assess whether the teams will combine for at least one run in the bottom of the ninth inning. The resolution depends exclusively on runs scored during this final inning.
Markets resolve to Yes if Arizona and Houston collectively score more than 0.5 or more than 1.5 runs in the 9th inning of their professional baseball game scheduled for Sep 4, 2026. Only runs scored during the 9th inning count, even if the home team doesn’t bat, unless the game is called early; a Fair Price applies if the inning is incomplete due to cancellation.
