PredictionHero - Resolution Divergence Alerts (RDA)

Divergence Detected

Issue: Cancellation handling differs between platforms. Polymarket explicitly resolves canceled games to 'No', while Kalshi does not specify a resolution path for cancellations.Hero tip: Consider the risk of a game cancellation, especially when trading on Kalshi, as the market may remain open or resolve based on limited data.

Critical divergence points:

  • Polymarket: Resolves to 'No' if the game is canceled entirely with no make-up game. Uses official statistics, then Flashscore/Sofascore/consensus if official data is unavailable. Resolution within 24 hours or 50/50 split.
  • Kalshi: Resolves based on the result after 90 minutes plus stoppage time. No explicit cancellation handling is mentioned, leaving resolution open-ended in that scenario.
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.

Polymarket

This event is for the upcoming Women's Super League game, scheduled for Sunday, September 27, 2026 between Chelsea FC and Arsenal WFC.

Kalshi

The event resolves based on the official result of the Chelsea vs Arsenal professional English Womens Super League soccer match scheduled for September 27, 2026, after 90 minutes plus stoppage time, excluding extra time or penalties. Three distinct outcomes are possible: Chelsea win, Arsenal win, or a tie. If the match concludes with either team securing a victory within regular time, the corresponding market will resolve to Yes. Should the game end in a tie after the same duration, the Tie market will resolve to Yes. In the event the match is cancelled or rescheduled to more than 48 hours beyond its original date, all markets will resolve to a fair price as determined by the platform rules. The resolution strictly follows the governing league's official match result and timing parameters, with no consideration given to post-match events such as disciplinary actions or subsequent league standings.

Frequently asked questions

Prediction market odds, like those reflected in this market, often differ from traditional sportsbook odds due to the differing incentives of participants. Sportsbooks aim to profit by setting lines that attract balanced betting, while prediction market participants are incentivized to accurately forecast the outcome. This can lead to prediction markets incorporating a wider range of information and potentially offering more accurate probabilities. Furthermore, the wisdom of the crowd effect often comes into play, where the collective judgment of many traders can outperform individual expert opinions. The volume of $598,469 suggests significant interest in this event.

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 on Polymarket and Kalshi can diverge due to several factors, including differences in user base, trading fees, and market-specific rules. Each platform attracts a different pool of traders with varying levels of expertise and risk tolerance, which influences price discovery. Additionally, the liquidity available on each platform can impact price volatility and spread. While both platforms track the same underlying event – the Chelsea vs. Arsenal match – these variations can lead to discrepancies in the implied probabilities. The current volume of $598,469 shows active trading across both venues.
