PredictionHero - Resolution Divergence Alerts (RDA)

Unified Resolution Criteria (Consistent across platforms)

All platforms agree on using the official ATP Tour scoring page as the resolution source and share consistent rules for match completion, cancellations, walkovers, and retirements.Primary resolution logic: Official ATP Tour scoring page

Core resolution logic:

  • The match must be officially completed per ATP rules to resolve most markets
  • Cancellations before play begins or unresolved matches beyond September 13 resolve as 50-50 or No
  • Walkovers and retirements have specific resolution conditions depending on market type
  • Over/under markets use completed games sets as defined by official statistics

Edge cases & clarifications:

  • Walkover: If a player withdraws before the match starts, markets resolve as 50-50 unless specified otherwise
  • Retirement: If a player retires during the match, the opposing player is considered the winner for winner markets
  • Match Not Completed: Markets resolve as 50-50 or No if the match is not completed by September 13, 2026, unless otherwise specified
Timing: Resolution occurs when official ATP Tour statistics are published post-match completion or at September 13, 2026 for unresolved matchesOur 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.

Opinion

In the upcoming ATP singles match scheduled for 2026-08-31 22:50 UTC: if Nuno Borges wins the match, this market resolves to "Nuno Borges"; if Learner Tien wins, it resolves to "Learner Tien". The winner is the first player to claim the required number of sets under the match's official best-of format. If the match begins but is not completed, a retirement or default counts the opposing player as the winner. If a walkover is declared before the first point is played, the match is outright canceled, or it is delayed beyond 7 days from the scheduled date without a winner determined, this market will resolve to 50-50. Suspensions caused by weather, fading light, or other tournament-imposed delays do not close this market — it stays open until the match is officially completed, provided it concludes within the 7-day window mentioned above. Resolution Source: The official ATP Tour scoring page. Note: This market will resolve strictly based on the first officially published result from the designated source. Any subsequent revisions will not affect this resolution.
