PredictionHero - Resolution Divergence Alerts (RDA)

Unified Resolution Criteria (Consistent across platforms)

All markets across platforms share identical resolution logic based on ATP statistics with consistent handling of incomplete matches and cancellations.Primary resolution logic: Official ATP statistics

Core resolution logic:

  • Match must be completed per ATP rules; otherwise 50-50 resolution
  • Tiebreaks count as one game toward total game counts
  • Cancellations before play or delays beyond 7 days resolve 50-50
  • Set and match winners determined by completed sets only

Edge cases & clarifications:

  • Retirement/Walkover: If a player advances due to retirement, the market resolves for the advancing player unless specified otherwise (e.g., walkovers resolve 50-50)
  • Delayed Matches: If a match is delayed beyond 7 days from scheduled date without a result, all markets resolve 50-50
Timing: Resolution occurs immediately after official ATP statistics are published for the match, typically within 2 hours of match conclusionOur 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 National Bank Open tennis match market aggregates real-time data from multiple venues, showing how traders price the contest between the two players. It displays current probabilities, volume of $566,338, and 24-hour volume of $565,295. This centralized view helps users compare sentiment across platforms and monitor shifts as the match approaches. Because it pulls from live markets, the dashboard offers a snapshot of collective expectations, letting participants spot trends before placing trades.

Prediction market odds on this market often differ from traditional sportsbook lines due to decentralized pricing and unique participant dynamics. Traders on platforms like Polymarket and Limitless set prices based on their own research and risk tolerance, which can create sharper or more volatile odds compared to aggregated sportsbook averages. For example, a sportsbook might round probabilities for simplicity, while prediction markets reflect fine-grained consensus. Additionally, prediction markets incorporate real-time sentiment shifts, so odds here can move faster than sportsbook lines as new information emerges.

On Polymarket and Limitless, prices can vary because each venue attracts different user bases and liquidity conditions. 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 instance, one platform might have deeper order books that dampen sudden swings, while the other could see sharper moves from fewer traders. Market design elements like fee structures or minimum order sizes also influence how users place bets, leading to divergent probability estimates. Moreover, external events such as player injuries or weather updates may impact each platform’s liquidity unevenly, causing temporary mismatches in pricing.
