PredictionHero - Resolution Divergence Alerts (RDA)

Divergence Detected

Issue: The scope of the event differs between platforms. Predict considers the entire match (90+ stoppage time), while Polymarket focuses solely on the first half (45+ stoppage time).Hero tip: Be mindful of the differing timeframes. Polymarket focuses solely on the first 45 minutes, while Predict considers the entire match. This significantly impacts the probability of 'Neither' resolving.

Critical divergence points:

  • Predict: The market resolves based on the first goal scored within the entire match (90 minutes + stoppage time). "If neither team scores within the first 90 minutes of regular play plus stoppage time, this market will resolve "Neither".
  • Polymarket: The market resolves based on the first goal scored within the first half (45 minutes + stoppage time). "If neither team scores in the first half (first 45 minutes of regular play plus first-half stoppage time), this market will resolve "Neither".
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.
