Description

Similar to the previous event, this market evaluates the early-game performance gap between A's and Boston, centered on whether Boston or A's secure a decisive lead within the first five innings. The result hinges on the size of the winning margin rather than just who wins.

Kalshi

Resolution occurs if Boston wins the first five innings by more than 2.5 or 1.5 runs, or if A's achieves the same margins in their favor. All markets remain active if the game is postponed or delayed, closing after the rescheduled match finishes within two days. The rules mirror the structure of the prior spread-based event, with identical timing and contingency provisions but applied to the A's vs Boston matchup.
