Description

This event covers various ways Boston or Arizona could lead after the first five innings of an upcoming baseball game. Each sub-market has different margin requirements for either team to win that segment.

Kalshi

These markets resolve based on the score differential after the first five innings of the specified Arizona vs Boston baseball game. Four separate sub-markets exist with varying run differentials: Boston winning by more than 2.5 runs, Boston winning by more than 1.5 runs, Arizona winning by more than 1.5 runs, and Arizona winning by more than 2.5 runs. If the game is postponed or delayed, all markets remain open and will close after the rescheduled game concludes within two days. Kalshi explicitly states it is not affiliated with the governing league, and all trademarks remain property of their respective owners.
