PredictionHero - Resolution Divergence Alerts (RDA)

Divergence Detected

Issue: The platforms offer different markets related to the same game, creating scope divergence. Predict and Polymarket focus on the game winner, while Polymarket also has a first inning run market and Kalshi has an extra innings market.Hero tip: Focus on the specific market you're trading. The core winner market is consistent, but the additional markets require separate analysis.

Critical divergence points:

  • Predict: This market will resolve to "Boston Red Sox" if the Boston Red Sox win the game, or "Texas Rangers" if the Texas Rangers win the game. Tie/cancellation resolves 50-50.
  • Polymarket: Offers both a winner market (identical to Predict) *and* a market on whether a run is scored in the first inning. Tie/cancellation resolves 50-50 for both.
  • Kalshi: Focuses on whether at least 1 extra inning is played in the game.
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.

Frequently asked questions

Prediction market odds, like those found in this market, often differ from traditional sportsbook odds due to the incentives and information sources involved. Sportsbooks set lines to balance action and ensure profit, while prediction markets allow participants to freely express their beliefs, creating a more accurate reflection of collective knowledge. This can lead to discrepancies, especially when public sentiment deviates from expert analysis. Furthermore, prediction markets benefit from continuous trading, allowing odds to adjust rapidly to new information, unlike sportsbooks which typically update less frequently.
