PredictionHero - Resolution Divergence Alerts (RDA)

Unified Resolution Criteria (Consistent across platforms)

All platforms utilize the same primary resolution source (MLB.com) and share consistent logic for postponements, cancellations, and tie games.Primary resolution logic: Official MLB statistics (mlb.com)

Core resolution logic:

  • Markets resolve based on final, official game statistics.
  • Postponed games remain open until completion.
  • Canceled games (no makeup) resolve 50-50.
  • Tie games are resolved according to the specific market's rules (typically favoring the opposing team in spread markets).
  • If official statistics aren't available within 24 hours, a consensus of credible reporting will be used.

Edge cases & clarifications:

  • Truncated Game: If a game is truncated but a final result is awarded by MLB, the market will resolve based on that official score.
  • Data Delay: If official statistics are delayed beyond 24 hours, a consensus of credible reporting sources will be used for resolution.
Timing: Resolution occurs upon the official completion of the game, as recognized by MLB.com, or within 24 hours of completion if official statistics are published. Otherwise, resolution occurs upon consensus of credible reporting.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 on Polymarket and Predict, often reflect the collective wisdom of a diverse group of participants, potentially offering a different perspective than traditional sportsbooks. Sportsbooks set lines based on their own models and risk management, while this market is driven by individuals wagering their own capital. This can lead to discrepancies, particularly when public sentiment strongly diverges from the sportsbook's initial assessment. While sportsbooks may initially focus on statistical probabilities, this market can quickly incorporate new information and adjust accordingly, potentially identifying undervalued or overvalued outcomes.

Polymarket and Predict can show different implied probabilities for the same outcome because of liquidity, fee structure, participant mix, and how each venue defines the contract. Prices on Polymarket and Predict may differ due to variations in user base, trading activity, and market-specific rules. Each platform attracts a different demographic of traders with varying levels of expertise and risk tolerance. Polymarket may have a higher concentration of sophisticated bettors, while Predict might be more influenced by casual participants. Furthermore, the liquidity and volume on each platform can impact price discovery. Differences in fees and trading limits can also contribute to price discrepancies, even when assessing the same event.
