Description

PredictionHero - Resolution Divergence Alerts (RDA)

Divergence Detected

Issue: Fundamental scope mismatch between professional NPB game winner and college baseball run total thresholdsHero tip: Verify the specific game type (professional vs college) for each contract before trading. These markets represent entirely different events and will never resolve together.

Critical divergence points:

  • Polymarket: Resolves to the winning team of the professional NPB game, remains open if postponed, and splits 50-50 for cancellations or ties
  • Kalshi: Resolves to Yes if total runs exceed specified thresholds (5.5, 7.5, 9.5, or 11.5) in a college baseball game scheduled for August 15, 2026
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 15 at 5:00AM ET: If the Tokyo Yakult Swallows win, the market will resolve to "Tokyo Yakult Swallows". If the Yokohama BayStars win, the market will resolve to "Yokohama BayStars". 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 event assesses multiple thresholds for the total runs scored by Yokohama DeNA BayStars and Tokyo Yakult Swallows in their college baseball game scheduled for August 15, 2026. Each threshold—over 5.5, 7.5, 9.5, and 11.5 runs—defines a separate market that resolves to 'Yes' if the combined score exceeds that level. All markets are based on the official game result and are independent of any affiliations with the governing league, with Kalshi explicitly stating it holds no official connection to the league. Trademarks and brand names remain the property of their respective owners.
