PredictionHero - Resolution Divergence Alerts (RDA)

Unified Resolution Criteria (Consistent across platforms)

Both Polymarket and Kalshi markets share identical resolution criteria regarding the 90-minute match result, handling of postponements, and cancellations.Primary resolution logic: Official statistics from the Turkish Football Federation (TFF.org)

Core resolution logic:

  • Resolution is based on the result within the first 90 minutes of regular play plus stoppage time.
  • If the game is canceled without a rescheduled date, win markets resolve to 'No' and the draw market resolves to 'Yes'.
  • If the game is postponed, markets remain open until completion.

Edge cases & clarifications:

  • Data Availability: If official statistics are unavailable within 2 hours of the match's conclusion, Flashscore data will be used, followed by Sofascore, and finally a consensus of credible reporting.
  • Score Revisions: Revisions to officially declared final scores after market resolution will not be considered.
Timing: Resolution will occur within 24 hours of the match's conclusion, or when acceptable data becomes available, up to that 24-hour limit.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 seen on Polymarket and Kalshi, often reflect the collective wisdom of a diverse group of traders, potentially offering a different perspective than traditional sportsbooks. Sportsbooks set lines based on models and internal risk assessments, while this market is driven by individuals betting with their own capital. As a result, discrepancies can arise due to differing information, biases, or risk appetites. Comparing the implied probabilities from both sources can provide a more nuanced understanding of the potential outcome of the Istanbulspor vs. Mardin match.

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. Differences in pricing between Polymarket and Kalshi for the Istanbulspor vs. Mardin match can stem from several factors. Each platform attracts a different user base with varying levels of expertise and access to information. Trading volume and liquidity also play a role; lower volume on one platform can lead to greater price volatility. Furthermore, the specific market mechanics and fee structures on Polymarket and Kalshi can influence trader behavior and, consequently, the resulting prices. These factors contribute to the dynamic interplay of probabilities observed across these prediction markets.
