This market will resolve to the player who wins the 2026 National League Rookie of the Year award for the 2026 MLB Season. In the event of a tie, this market will resolve according to the official winner as determined by MLB rules. If multiple winners are announced then this market will resolve to the player whose listed last name comes first alphabetically. If the 2026 MLB season is cancelled, postponed after December 31, 2026, 11:59 PM ET, or there is otherwise no winner declared within that timeframe, this market will resolve to “Other”. The resolution source for this market will be official information from Major League Baseball; however, a consensus of credible reporting may also be used.

Outcomes are resolved by Polymarket (UMA oracle). Papermarket mirrors the official resolution.
