PredictionHero - Resolution Divergence Alerts (RDA)

Divergence Detected

Issue: Significant divergence in market scope and resolution criteria, particularly regarding incomplete matches and cancellation policies.Hero tip: Consider the potential for matches to be abandoned or incomplete, and how each platform handles these scenarios. Polymarket's 14-day window introduces additional risk.

Critical divergence points:

  • Limitless: Focuses on specific set-related outcomes with detailed rules for incomplete matches and tiebreakers. Resolves based on completed play or 50/50 splits. 'If the match begins but is not completed, this market will resolve 50-50.'
  • Polymarket: Primarily focuses on match winner and completed match, with a 50/50 resolution for cancellations, walkovers, or incomplete matches. Has a 14-day delay window for resolution. 'If the match is canceled (not played at all), ends in a tie, or a winner has not been determined by September 16, 2026, 11:59 PM ET (14 days after the scheduled start), this market will resolve to 50-50.'
Our PredictionHero Resolution Divergence Alerts (RDA) are there to help users identify potential differences across platforms.

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 for this market, often differ from traditional sportsbook odds due to the wisdom of the crowd and incentive structures. Sportsbooks set odds to ensure profit, incorporating a margin, while prediction markets allow traders to directly express their beliefs. This can lead to more accurate probabilities, especially as the event approaches and more volume is traded. However, sportsbooks have access to different information, such as team news and injuries, which may not be immediately reflected in prediction market prices. The current volume for this market is $93,034.

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. Prices on Polymarket and Limitless can diverge due to several factors. Each platform has a different user base with varying expertise and information. Trading volume also plays a role; a market with low volume on one platform may be more susceptible to price swings. Additionally, the specific question framed on each platform can influence prices. For example, one platform might focus on the total number of sets played, while the other asks about a specific player winning. These differing approaches can result in contrasting probabilities, even for the same underlying event.
