Rules

Polymarket

This market will resolve according to the club that wins the 2026 Japan Series (the Nippon Professional Baseball championship series).

If at any point it becomes impossible for a listed club to win the 2026 Japan Series (e.g., they are eliminated), the corresponding market will resolve to "No".

If the 2026 NPB postseason is cancelled, postponed after November 30, 2026, 11:59 PM ET, or there is otherwise no Japan Series champion declared within that timeframe, this market will resolve to "Other".

The primary resolution source will be official information from NPB (https://npb.jp); however, a consensus of credible reporting may also be used.
