For the fifth inning, participants will look for any scoring activity. The market considers even a single run sufficient to achieve a positive outcome.
Markets resolve to Yes if the Oakland Athletics and Tampa Bay collectively score more than 0.5 runs in the 5th inning of their professional baseball game scheduled for September 15, 2026. Only runs scored during the 5th inning count; if the game is called early before the inning completes, the market resolves to a Fair Price.
