PredictionHero - Resolution Divergence Alerts (RDA)

Divergence Detected

Issue: Polymarket explicitly handles game cancellation by resolving to 'No', while Kalshi does not mention cancellation, implying the game must be played for resolution.Hero tip: Consider the likelihood of game cancellation when trading. Polymarket offers a defined outcome for this scenario, while Kalshi's market implicitly requires the game to occur.

Critical divergence points:

  • Polymarket: Resolves to 'No' if the game is canceled entirely. Uses a hierarchy of official sources, then Flashscore/Sofascore/consensus reporting. Key Quote: "If the game is canceled entirely, with no make-up game, this market will resolve 'No'."
  • Kalshi: Implies the game must be played for resolution. Does not explicitly address cancellation. Key Quote: "If Tie is the result of the Washington vs Boston Legacy FC professional NWSL soccer game originally scheduled for Sep 13, 2026 after 90 minutes plus stoppage time... then the market resolves to Yes."
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.

Prediction market odds, like those found in this market, often differ from traditional sportsbook odds due to the differing incentives and information sources. Sportsbooks set odds to maximize profit, incorporating a margin for themselves, while prediction markets allow participants to directly express their beliefs. This can lead to prediction markets being more efficient at reflecting true probabilities, especially when there is significant public interest and information available. However, sportsbooks often have lower transaction costs and wider accessibility. The current implied probability from this market may not perfectly align with those offered by traditional sportsbooks.
