Description

This event tracks the performance of two baseball teams over the first five innings of their scheduled game. It focuses on the margin of victory for each team within that specific segment of the match, providing insight into early-game dominance. The outcome depends entirely on the runs scored during this initial period.

Kalshi

The event consists of four separate markets, each evaluating different run-spread scenarios for the first five innings of the A's vs. Tampa Bay baseball game scheduled for September 17, 2026. Each market resolves based on whether the specified team wins by a margin greater than the designated run line within those first five innings. If Tampa Bay wins by more than 2.5 or 1.5 runs, respective markets resolve to Yes. Conversely, if the A's win by more than 1.5 or 2.5 runs, their corresponding markets resolve to Yes. All markets remain open if the game is postponed or delayed, closing only after the rescheduled game concludes within two days. The event is unaffiliated with the governing league, and all trademarks belong to their respective owners.
