Description

This event tracks the outcome of the first five innings of a professional baseball game between two teams scheduled for a specific date and time. It focuses on whether one team leads, the other team leads, or the game is tied after those initial innings. The market remains active if the game is postponed and resolves once the rescheduled game completes.

Kalshi

The event determines the result of the first five innings of the professional baseball game between Kansas City and Boston scheduled for September 12, 2026, at 4:10 PM EDT. Three possible outcomes are considered: Kansas City winning the first five innings, Boston winning the first five innings, or the game being tied after those innings. If the game is tied at the end of the fifth inning, the 'Tie' outcome is resolved as Yes, and both team-specific outcomes ('Kansas City wins first 5 innings' and 'Boston wins first 5 innings') resolve as No. If the originally scheduled game is postponed or delayed, all markets remain open and will resolve after the rescheduled game concludes, provided the rescheduled date occurs within two days of the original date. The governing rules ensure clarity regarding tied scores and postponent handling, while emphasizing that Kalshi is not officially affiliated with the governing league.
