PredictionHero - Resolution Divergence Alerts (RDA)

Divergence Detected

Issue: Kalshi defines a win for either team as 'Yes', while Polymarket specifies the winning team's name as the resolution.Hero tip: Polymarket provides a clearer resolution path by directly naming the winning team. Kalshi's 'Yes' resolution is less informative but functionally equivalent.

Critical divergence points:

  • Polymarket: Resolves to the winning team's name (Yokohama BayStars or Tokyo Yakult Swallows). "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 to 'Yes' if either team wins. "If Tokyo Yakult Swallows wins the market resolves to Yes. If Yokohama DeNA BayStars wins the market resolves to Yes."
