PredictionHero - Resolution Divergence Alerts (RDA)

Divergence Detected

Issue: These markets reference entirely different games (professional NPB vs college baseball) with distinct resolution criteria despite sharing the same date and teamsHero tip: Treat these as separate markets. The Polymarket market resolves based on the professional NPB game result, while Kalshi markets resolve based on run totals in a college game. Verify game types before trading.

Critical divergence points:

  • Polymarket: Resolves based on winner of NPB professional game: 'If the Chiba Lotte Marines win... If the Saitama Seibu Lions win... If the game is canceled entirely... this market will resolve 50-50'
  • Kalshi: Resolves based on total runs in college baseball game: 'If Saitama Seibu Lions and Chiba Lotte Marines collectively score more than X.5 runs... then the market resolves to Yes' (with four separate threshold markets)
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

In the upcoming NPB game, scheduled for August 4 at 5:00AM ET: If the Chiba Lotte Marines win, the market will resolve to "Chiba Lotte Marines". If the Saitama Seibu Lions win, the market will resolve to "Saitama Seibu Lions". If the game is postponed, this market will remain open until the game has been completed. If the game is canceled entirely, with no make-up game, or ends in a tie, this market will resolve 50-50. The primary resolution source will be official information from the NPB. A consensus of credible reporting may also be used.

Kalshi

The markets resolve based on whether the total runs scored by both teams in the specified college baseball game exceed predefined thresholds of 5.5, 7.5, 9.5, or 11.5 runs. Each threshold represents a distinct level of scoring volume, allowing participants to assess varying degrees of offensive performance in the match. All markets are independent, and each resolves separately according to its specific run total requirement. Kalshi explicitly disclaims any official affiliation with the governing league, and all trademarks remain the property of their respective owners.
