PredictionHero - Resolution Divergence Alerts (RDA)

Divergence Detected

Issue: Fundamental scope difference between markets - Kalshi resolves based on Chiba Lotte Marines vs Tohoku Rakuten Golden Eagles game outcome (with illogical always-Yes condition), while Polymarket resolves based on Tohoku Rakuten Golden Eagles vs Saitama Seibu Lions game outcomeHero tip: Do not treat these markets as correlated. Kalshi's logic appears flawed or misconfigured as it would resolve to Yes regardless of actual game outcome. Focus resolution monitoring exclusively on the Tohoku Rakuten Golden Eagles vs Saitama Seibu Lions game for Polymarket. If the Chiba Lotte Marines vs Tohoku Rakuten Golden Eagles game is canceled with no makeup date, Kalshi may remain permanently unresolved.

Critical divergence points:

  • Kalshi: Market resolves to Yes if Chiba Lotte Marines wins OR if Tohoku Rakuten Golden Eagles wins the Aug 19, 2026 game against Chiba Lotte Marines - effectively guaranteeing a Yes resolution unless the game is canceled with no makeup date
  • Polymarket: Market resolves to "Tohoku Rakuten Golden Eagles" if they win the Aug 23, 2026 game against Saitama Seibu Lions, resolves to "Saitama Seibu Lions" if they win, remains open for postponements, and splits 50-50 for cancellations or ties
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 23 at 3:00AM ET: If the Tohoku Rakuten Golden Eagles win, the market will resolve to "Tohoku Rakuten Golden Eagles". 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

This event involves two primary rules corresponding to each team's potential victory in a scheduled Japan NPB game on August 19, 2026. If the Chiba Lotte Marines win, the first market resolves to Yes; if the Tohoku Rakuten Golden Eagles win, the second market resolves to Yes. In the event of a tie, both markets resolve to a 50/50 outcome. Postponements or delays within two days of the original schedule will keep markets open until the rescheduled game concludes. Cancellations or rescheduling beyond two days will result in a fair price resolution. Kalshi disclaims any official affiliation with the Governing League, and all trademarks remain property of their respective owners.
