Description

This set of markets focuses on predicting whether one team will hold a significant lead after the first five innings of an upcoming baseball game. Each market specifies a different margin of victory required for the outcome to be considered successful. The markets remain active even if the game is rescheduled, closing only after the rescheduled game's first five innings conclude.

Kalshi

These markets assess various run differential thresholds for either Boston or the A's to win by within the first five innings of their scheduled game on July 29, 2026. Each market has a specific spread requirement: the A's must win by more than 2.5 or 1.5 runs, while Boston must win by more than 1.5 or 2.5 runs in the first five innings for the respective market to resolve as 'Yes.' If the game is postponed or delayed, all markets stay open and will close after the rescheduled game’s first five innings are completed, provided the reschedule occurs within two days of the original date. The markets are independent of any official league affiliations, and all trademarks remain the property of their respective owners.
