Description
This event group predicts which Major League Baseball team will win the 2026 World Series. Markets across Polymarket and Predict platforms cover all 30 MLB teams plus an 'other' catch-all option, with consistent resolution criteria tied to official MLB outcomes.
PredictionHero - Resolution Divergence Alerts (RDA)
Unified Resolution Criteria (Consistent across platforms)
Both platforms apply the same three-outcome framework (YES/NO/OTHER) with identical trigger conditions, source hierarchy, and deadline (December 31, 2026 ET).
Primary resolution logic:
Official MLB information (https://www.mlb.com/); consensus of credible reporting as secondary sourceCore resolution logic:
- Market resolves YES if the specified team wins the 2026 MLB World Series
- Market resolves NO if the specified team is eliminated from playoff contention per MLB rules
- Market resolves OTHER if the 2026 MLB season is cancelled, postponed after December 31, 2026 ET, or no winner is declared within that timeframe
- The 'another team' or catch-all option resolves YES if any team not explicitly listed wins the World Series
Edge cases & Clarifications:
- Season Cancellation: If the 2026 MLB season is cancelled for any reason (labor dispute, force majeure, etc.), all individual team markets resolve to OTHER
- Playoff Elimination: Once a team is mathematically eliminated from playoff contention, its corresponding market immediately resolves to NO
- Deadline Extension: If the World Series extends beyond December 31, 2026 ET due to scheduling, markets resolve based on the outcome whenever declared; if no outcome by that date, resolution is OTHER
- Mutual Exclusivity: Exactly one team market will resolve YES; all others resolve NO (or OTHER if season fails). The catch-all 'another team' option resolves NO if any listed team wins
Timing:
Resolution occurs immediately upon official declaration of the 2026 World Series champion by MLB, or by December 31, 2026 ET deadline (whichever triggers first); if no champion declared by deadline, all markets resolve OTHEROur PredictionHero Resolution Divergence Alerts (RDA) are there to help users identify potential differences across platforms.
