Description
This market will resolve according to the team that wins the 2026 MLB World Series. If at any point it becomes impossible for a listed team to win the 2026 MLB World Series per the rules of MLB (e.g., they are eliminated in the playoffs), the corresponding market will resolve to “No”. If the 2026 MLB season is cancelled, postponed after December 31, 2026 ET, or there is otherwise no winner declared within that timeframe, this market will resolve to “Other”. The primary resolution source will be official information from MLB (https://www.mlb.com/); however, a consensus of credible reporting may also be used.
Description
If St. Louis wins the 2026 Pro Baseball Championship, then the market resolves to Yes.
