PredictionHero - Resolution Divergence Alerts (RDA)

Unified Resolution Criteria (Consistent across platforms)

All markets share identical resolution logic and sourcesPrimary resolution logic: Official MLB statistics or credible reporting consensus

Core resolution logic:

  • Winner market resolves to the team that wins the game; ties or cancellations resolve 50-50
  • First-inning runs market resolves to Yes if either team scores in the first inning, No otherwise

Edge cases & clarifications:

  • Postponement: Markets remain open until game is completed
  • Cancellation: Markets resolve 50-50 if no makeup game is scheduled
  • Tie: Winner market resolves 50-50; first-inning market resolves based on actual inning play
Timing: Resolution occurs after official MLB statistics are published or within 24 hours of game conclusion using credible reporting consensusOur 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

The dashboard for the Cubs vs. D-backs matchup market aggregates real-time data from multiple prediction platforms, showing how traders price the likelihood of various outcomes. It displays current probabilities, volume of $868,323, and 24-hour volume of $811,809, letting you see consensus views and divergences across venues. This unified view helps you spot shifts in sentiment as the game approaches, with all data updated live to reflect market activity.

On Polymarket and Predict, prices can vary because each platform attracts different user bases and has distinct liquidity pools. 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. For example, one venue might see heavier participation from seasoned traders who react quickly to pitching changes or weather updates, while the other could be influenced more by casual fans. These differences in activity and information flow often create temporary mispricings between the two sites.

Injuries to key players, weather delays, or last-minute lineup changes could shift this market as they affect expected scoring. Bets will also react to any pre-game betting surges, especially if one side gains sudden public favor or if internal team news leaks out. All of these catalysts can cause rapid swings in probability and volume before the final whistle.
