PredictionHero - Resolution Divergence Alerts (RDA)

Unified Resolution Criteria (Consistent across platforms)

Both platforms use ATP Tour official results to determine exact set scores, with consistent handling of match completions and incompletesPrimary resolution logic: Official ATP Tour

Core resolution logic:

  • Match must be completed with a valid set score of either 3-0, 3-1, or 3-2 for either player
  • Any match not completed (cancellation, retirement, walkover) resolves as 'Not Completed'
  • Only the exact final set score determines resolution - no partial progress or alternative outcomes considered

Edge cases & clarifications:

  • Retirement/Walkover: If a player advances without completing the match (retirement, walkover, default), all exact score markets resolve as 'Not Completed'
  • Match Delay: If the match is delayed beyond 14 days from scheduled time without completion, it resolves as 'Not Completed'
Timing: Resolution occurs immediately after the official ATP Tour result is published, typically within 24 hours of match completionOur 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.

Polymarket

In the upcoming US Open ATP singles match between Jan Choinski and Botic van de Zandschulp, scheduled for August 30, 2026 at 11:00AM ET: This market will resolve based on the final set score of the Jan Choinski vs. Botic van de Zandschulp match. This match is played in a best-of-5-sets format. The possible outcomes are 3-0, 3-1, “Not Completed”, and 3-2 in either direction. If the match is canceled (not played at all), or is delayed beyond 14 days from the scheduled date at 11:59 PM ET without completion, this market will resolve to 'Not Completed'. If the match begins but is not completed, and one player advances due to the opponent's retirement, default, or disqualification, this market will resolve to 'Not Completed' regardless of the set score at the time. If the match ends in a walkover (player withdraws before the start and the other advances automatically), this market will resolve to 'Not Completed'. The primary resolution source will be official information from the ATP Tour. A consensus of credible reporting may also be used.

Kalshi

These markets resolve based on the exact set score of the Jan Choinski vs Botic Van de Zandschulp professional tennis match in the 2026 US Open Men Singles Round Of 128. A market resolves to Yes only if the match concludes with the specific set score outlined in its title (e.g., 3-0, 3-1, or 3-2 for either player). If the match does not occur due to injury, walkover, forfeiture, or other cancellation before any ball is played, all markets resolve to a fair price. If the match is postponed or delayed, markets remain open until the rescheduled match concludes, with resolution occurring within two weeks after the match finishes. In cases of retirement, markets that can be settled based on completed play resolve accordingly, while unresolved markets settle at Fair Market Price determined by the Exchange. The Exchange disclaims any official affiliation with the governing league, and all trademarks remain property of their respective owners.
