Japan J. League: Winner

This market will resolve to "Yes" if the listed club is determined as the champion of the Japan J. League. Otherwise, it will resolve to "No". If at any point it becomes impossible for a listed participant to be named as the champion of Japan J. League per the rules of Japan J. League (e.g., participant is eliminated), the corresponding market will resolve to "No". If multiple teams are declared winners, this market will resolve in favor of the team whose listed name comes first alphabetically. If this event is cancelled, postponed after June 8, 2026, 11:59 PM ET, or a champion has not been declared within this timeframe, this market will resolve to "Other". The resolution source will be official information from the Japan J. League; 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.
