Description

This set of markets tracks the margin of victory in an upcoming professional baseball game between Boston and the A's. Each market corresponds to a specific run differential threshold that determines the outcome. The collective markets provide a detailed view of potential score variations for the contest.

Kalshi

These markets resolve based on the run differential in the professional baseball game between Boston and the A's originally scheduled for July 28, 2026, at 9:40 PM EDT. If the A's win by a margin exceeding 3.5, 2.5, or 1.5 runs, the respective 'A's wins by over X runs' markets resolve to Yes. Conversely, if Boston wins by a margin exceeding 1.5, 2.5, or 3.5 runs, the corresponding 'Boston wins by over X runs' markets resolve to Yes. All markets are independent and resolve solely based on the final confirmed score of the game as officially recorded by the governing league. Kalshi explicitly states it holds no affiliation or official connection with the governing league, and all trademarks, logos, and brand names referenced belong to their respective owners.
