Unified Resolution Criteria (Consistent across platforms)

All platforms utilize the same resolution criteria based on official MLB game statistics, with consistent handling of postponements, cancellations, and ties.Primary resolution logic: Official MLB statistics (mlb.com)

Core resolution logic:

  • The Chicago Cubs market resolves to 'Chicago Cubs' if the Cubs win the game.
  • The Boston Red Sox market resolves to 'Boston Red Sox' if the Red Sox win the game.
  • The 'Run in First Inning' market resolves to 'Yes' if at least one run is scored in the first inning by either team, and 'No' otherwise.

Edge cases & clarifications:

  • Postponement: If the game is postponed, the market remains open until the game is completed.
  • Cancellation/Tie: If the game is canceled entirely with no make-up game, or ends in a tie, the market resolves 50-50.
  • Delayed Statistics: If official statistics are not published within 24 hours, a consensus of credible reporting will be used.
Timing: Resolution will occur after the official completion of the game, typically within 24 hours, or when a consensus of credible reporting is established if official statistics are delayed.Our PredictionHero Resolution Divergence Alerts (RDA) are there to help users identify potential differences across platforms.

Frequently asked questions

Prediction market odds, like those found on Polymarket and Predict, often reflect the wisdom of the crowd, potentially differing from traditional sportsbook odds. Sportsbooks set lines based on their own models and aim to balance action on both sides, while this market allows anyone to express their belief, leading to a more diverse range of opinions influencing the price. This can result in prediction markets being more accurate, especially when considering information not fully captured by sportsbook algorithms. The current volume on this market is $746,345.

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 diverge due to variations in user base, trading activity, and market-specific rules. Polymarket might attract a different type of trader than Predict, leading to differing interpretations of the same information regarding the Cubs vs. Red Sox game. Additionally, the liquidity and volume on each platform can influence price discovery. While both platforms aim to predict the same outcome, these factors can create temporary discrepancies in the odds.
