PredictionHero - Resolution Divergence Alerts (RDA)

Unified Resolution Criteria (Consistent across platforms)

All platforms agree on the core resolution logic, utilizing official match results as the primary source and defining resolution based on the 90-minute result.Primary resolution logic: Official Liga Portugal statistics (https://www.ligaportugal.pt/)

Core resolution logic:

  • Resolution is based on the result within the first 90 minutes of regular play plus stoppage time.
  • If the game is postponed, the market remains open until completion.
  • If the game is canceled entirely, win markets resolve to 'No' and the draw market resolves to 'Yes'.

Edge cases & clarifications:

  • Data Availability: If official statistics are unavailable within 2 hours of the match conclusion, Flashscore data will be used. If Flashscore data is unavailable, Sofascore data will be used. If neither is available, a consensus of credible reporting will be used. If no acceptable data is available within 24 hours, the market will resolve 50-50 or to 'Draw' where applicable.
Timing: Resolution will occur as soon as official match statistics are available, but no later than 24 hours after the scheduled end of the match.Our 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

Prediction market odds, like those found on Polymarket and Kalshi for this market, often reflect a more diverse range of information than traditional sportsbook odds. Sportsbooks primarily use statistical models and expert analysis, while prediction markets incorporate the insights of many individual bettors. This can lead to differences in implied probabilities, especially when significant public information isn’t fully priced into sportsbook lines. However, both types of odds aim to accurately forecast the likelihood of an event, and discrepancies can present opportunities for arbitrage or informed betting.

Polymarket and Kalshi can show different implied probabilities for the same outcome because of liquidity, fee structure, participant mix, and how each venue defines the contract. Prices for the Rio Ave vs. Nacional match may differ between Polymarket and Kalshi due to variations in user base, trading activity, and market design. Each platform attracts different types of traders with varying levels of expertise and access to information. Furthermore, the liquidity and volume on each platform can influence price discovery. Polymarket might have a more active trading community focused on football, while Kalshi could have a broader user base with different interests, leading to differing price assessments for this market.
