MLS Cup Winner 2026

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.

How trading works

Polymarket uses a central limit order book (CLOB) model — you can buy or sell shares of any outcome at the current market price, or place limit orders. Prices represent implied probability: a $0.65 contract means the market prices a 65% chance of that outcome.
