Arizona vs Boston: First 5 Spread

Kalshi

The markets evaluate whether Arizona or Boston wins the first five innings of their scheduled game by a specified margin. Four separate outcomes exist: Boston winning by more than 2.5 or 1.5 runs, and Arizona winning by more than 1.5 or 2.5 runs, all measured within the first five innings. If the originally scheduled game is postponed or delayed, all markets remain open and will close only after the rescheduled game concludes, provided the reschedule occurs within two days of the original date. The outcome is determined solely based on the runs scored during the first five innings, regardless of the final full-game result.
