PredictionHero - Resolution Divergence Alerts (RDA)

Divergence Detected

Issue: Three distinct resolution frameworks exist: Polymarket separates match completion (YES/NO) from winner determination and uses 50-50 for walkovers; Limitless and Kalshi resolve to the advancing player regardless of completion method; Kalshi requires a ball to be played but does not address forfeits explicitly.Hero tip: Treat Polymarket's 'Completed Match' market as a separate bet on match integrity, not winner. If you expect a walkover or retirement, Polymarket NO will outperform Limitless/Kalshi winner markets. Cross-check player status 24 hours before match time. The Polymarket winner market (question 4) with 50-50 walkover resolution is a middle ground but still diverges from Limitless/Kalshi on forfeits mid-match.

Critical divergence points:

  • Polymarket (Completed Match): Resolves YES only if all games and sets are completed through normal play. Resolves NO on any forfeit, walkover, retirement, default, disqualification, cancellation, tie, or delay beyond 7 days. Key Quote: 'If a forfeit of any kind occurs, including but not limited to a walkover or retirement, this market will resolve No.'
  • Polymarket (Winner Market): Resolves to advancing player if match begins and one player advances via retirement/default/disqualification. Resolves 50-50 on walkover (pre-match withdrawal) or cancellation. Key Quote: '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 the player who advances. If the match ends in a walkover...this market will resolve to 50-50.'
  • Limitless: Resolves to officially declared winner regardless of completion method. Explicitly includes walkover, retirement, withdrawal, default, and disqualification as valid winner-determining outcomes. Key Quote: 'a player officially declared the winner of the match will be considered to have defeated the opponent, including in cases of walkover, retirement, withdrawal, default, or disqualification.'
  • Kalshi: Resolves YES if either player wins after a ball has been played. Does not explicitly address forfeits, walkovers, or retirements. Requires at least one ball to be played. Key Quote: 'after a ball has been played.'

Frequently asked questions

PredictionHero aggregates trader sentiment on the Mejia vs Zheng boxing match across multiple prediction platforms, including Polymarket and Kalshi. The dashboard displays real-time odds, historical price movements, and consensus probability estimates as traders position themselves ahead of the event. By tracking the same outcome across venues, you gain visibility into how different market microstructures and user bases price the matchup, revealing where conviction is strongest and where arbitrage opportunities may exist.

Prediction markets and sportsbooks price outcomes using different mechanisms. Sportsbooks set lines to balance liability and extract a margin; prediction markets let traders set prices through supply and demand. This market's odds reflect what traders believe will happen, often incorporating real-time information faster than traditional sportsbooks adjust. Comparing the two can reveal sharp consensus or highlight where public perception diverges from expert opinion, making prediction markets a useful reference point for serious bettors and analysts.

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. Each platform attracts different trader demographics, liquidity pools, and fee structures, all of which influence pricing. Polymarket and Kalshi may also enforce distinct rules around order types, settlement timing, or market halts. Temporary imbalances in buy and sell pressure on one venue can create a spread between platforms. These differences typically narrow as informed traders arbitrage the gap, but they can persist if regulatory constraints or withdrawal friction limit cross-platform trading.
