This market will resolve according to the team that wins the 2027 MLB World Series.
If at any point it becomes impossible for a listed team to win the 2027 MLB World Series per the rules of MLB (e.g., they are eliminated in the playoffs), the corresponding market will resolve to "No".
If no 2027 MLB regular-season game has been played by July 1, 2027, 11:59 PM ET, this market will resolve to "Other".
If the 2027 MLB season is cancelled, postponed after November 15, 2027, 11:59 PM 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.
Scheduled resolution: Oct 31, 2027.
