Intro

This market tracks the outcome of an upcoming NPB baseball game between the Nippon Ham Fighters and the Chiba Lotte Marines. The aggregated consensus probability for the leading outcome stands at 10.0%. Data is drawn from Polymarket and Kalshi, with resolution governed by https://npb.jp/. The critical catalyst to monitor will be the game itself, scheduled for August 1, which will determine the final result and market resolution.

PredictionHero - Resolution Divergence Alerts (RDA)

Divergence Detected

Issue: Fundamental logic mismatch: Polymarket uses team-name outcomes with tie/cancellation handling, while Kalshi incorrectly maps both outcomes to 'Yes' with no 'No' optionHero tip: Do not trade Kalshi until resolution logic is corrected. Use Polymarket for accurate NPB game outcome exposure. Monitor NPB official channels for game status updates.

Critical divergence points:

  • Polymarket: Resolves to team name if that team wins, 50-50 for ties/cancellations. Uses official NPB information as primary source with credible reporting consensus as backup. Key quote: If game is canceled entirely... resolves 50-50
  • Kalshi: Incorrectly resolves to Yes for either team win with no No outcome option. Lacks tie/cancellation handling. Key quote: If Hokkaido Nippon-Ham Fighters wins... market resolves to Yes (no corresponding No market)
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.
