PredictionHero - Resolution Divergence Alerts (RDA)

Divergence Detected

Issue: Kalshi is referencing a completely different game (Yokohama BayStars vs. Yomiuri Giants) while Polymarket correctly identifies the game as Yokohama BayStars vs. Tokyo Yakult Swallows. This makes the Kalshi market fundamentally unresolvable for this event.Hero tip: Do not trade the Kalshi market. It is for a different game and will likely resolve incorrectly. Focus exclusively on the Polymarket market for this event.

Critical divergence points:

  • Polymarket: Resolves to 'Yokohama BayStars' if they win, or 'Tokyo Yakult Swallows' if they win the game scheduled for September 8th at 5:00AM ET. If the game is postponed, the market remains open. If canceled or tied, it resolves 50-50. "If the Yokohama BayStars win, the market will resolve to 'Yokohama BayStars'. If the Tokyo Yakult Swallows win, the market will resolve to 'Tokyo Yakult Swallows'."
  • Kalshi: Resolves Yes if either the Yokohama DeNA BayStars or Yomiuri Giants win a game originally scheduled for Sep 2, 2026 at 5:00 AM EDT. "If Yokohama DeNA BayStars wins the Yokohama DeNA BayStars vs Yomiuri Giants Japan NPB game originally scheduled for Sep 2, 2026 at 5:00 AM EDT, then the market resolves to Yes."

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.

Prediction market odds, like those found in this market, often reflect a different kind of wisdom than traditional sportsbooks. Sportsbooks set lines to balance action and incorporate a profit margin, while prediction markets are driven by individuals betting with their own capital. This can lead to differences in probabilities, as prediction markets can sometimes be more efficient at incorporating diverse information and identifying mispriced outcomes. However, both types of odds provide valuable insights into the perceived likelihood of different results, and discrepancies can present arbitrage opportunities for informed traders.
