PredictionHero - Resolution Divergence Alerts (RDA)

Unified Resolution Criteria (Consistent across platforms)

Both platforms share identical resolution logic for determining the match winner and handling edge cases such as cancellations, retirements, and walkovers.Primary resolution logic: Official information from the ATP Tour, with credible reporting as a secondary source if necessary

Core resolution logic:

  • Resolve to the advancing player if the match concludes with a winner, including cases of retirement, default, or disqualification
  • Resolve to 50-50 for cancellations, ties, delays beyond 7 days, or walkovers
  • The Completed Match market resolves to "Yes" only if all required games and sets are played to completion through normal play

Edge cases & clarifications:

  • Retirement/Default/Disqualification: If one player advances due to the opponent's retirement, default, or disqualification, the market resolves to the advancing player
  • Walkover: If a player withdraws before the start, the market resolves to 50-50
  • Match Not Completed: If the match begins but is not completed, and one player advances due to the opponent's retirement, default, or disqualification, the market resolves to the player who advances
Timing: Resolution occurs once official ATP Tour information confirms the match result, or within 2 hours after the event's conclusion if official statistics are delayed, using credible reporting as a secondary sourceOur 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

On Polymarket and Limitless, prices can vary because each platform attracts different user bases and liquidity patterns. Polymarket and Limitless 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 may see heavier trading from tennis specialists, skewing its chances, while the other could reflect broader, less-informed sentiment. These differences in participation and depth help explain why the same event can show distinct implied probabilities across sites.
