This market will resolve according to the team that wins the 2026 MLS Cup. If at any point it becomes impossible for a listed team to win the 2026 MLS Cup per the rules of MLS (e.g. they are mathematically eliminated), the corresponding market will resolve to “No”. If the 2026 MLS 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 Major League Soccer; however, a consensus of credible reporting may also be used.
