Description

This group resolves to whether a specific team wins the 2026 Japan Series, the championship series of Nippon Professional Baseball (NPB). The markets cover all twelve teams in NPB, with individual markets for each team's chances of winning.

PredictionHero - Resolution Divergence Alerts (RDA)

Unified Resolution Criteria (Consistent across platforms)

Both platforms fundamentally agree on the resolution criteria: the winner of the 2026 Japan Series determines the outcome of each team's market.Primary resolution logic: Official NPB (https://npb.jp)

Core resolution logic:

  • A team's market resolves to 'Yes' if that team wins the 2026 Japan Series.
  • If the 2026 NPB postseason is cancelled, postponed after November 30, 2026, 11:59 PM ET, or no champion is declared, all markets resolve to 'Other'.

Edge cases & clarifications:

  • Postponement: If the Japan Series is postponed but eventually played in 2027, the markets will *not* resolve to 'Other', but will resolve based on the 2027 champion.
  • Tie: In the extremely unlikely event of a tie, official NPB tie-breaking procedures will determine the champion, and the corresponding market will resolve accordingly.
Timing: Resolution will occur once the official winner of the 2026 Japan Series is declared by NPB, or if the series is cancelled/postponed beyond the specified date.Our PredictionHero Resolution Divergence Alerts (RDA) are there to help users identify potential differences across platforms. They do not replace or supersede the official rules and description of any prediction market. Users are solely responsible for reviewing and understanding the applicable rules and resolution criteria before placing any trade or bet. If you notice a potential inconsistency, discrepancy, or error in an alert, please report it to our team so we can review and improve the accuracy of our data.

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.
