Description

These markets focus on predicting whether either team will hold a specified lead after the first five innings of an upcoming baseball game. The outcomes depend strictly on the score differential at that specific midpoint of the contest. Any changes to the game's schedule will not affect the market resolution as long as the game eventually takes place.

Kalshi

All four markets resolve based solely on the score difference after the first five innings of the Boston vs A's professional baseball game originally scheduled for July 27, 2026. Each market specifies a different run-line threshold: the Athletics must win by more than 2.5 or 1.5 runs, or Boston must win by more than 1.5 or 2.5 runs within that timeframe for the respective market to settle as 'Yes.' If the game is postponed or delayed, all markets remain open and will close only after the rescheduled game concludes, provided the makeup game is completed within two days of its new scheduled date. No affiliation or endorsement by the governing league is implied, and all trademarks remain the property of their respective owners.
