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 in the contest.

Kalshi

The markets resolve based on the run differential from the Boston vs A's professional baseball game scheduled for July 30, 2026, at 9:40 PM EDT. If the A's win by exceeding specified run margins—over 3.5, over 2.5, or over 1.5 runs—the corresponding 'A's wins by over X runs' markets resolve to Yes. Conversely, if Boston wins by margins greater than 1.5, 2.5, or 3.5 runs, the respective 'Boston wins by over X runs' markets resolve to Yes. All markets are independent, and only the specific threshold-based outcomes defined in each rule determine resolution. Kalshi disclaims any official affiliation with the governing league, and all trademarks remain property of their respective owners.
