PredictionHero - Resolution Divergence Alerts (RDA)

Divergence Detected

Issue: The Polymarket markets focus on the single match outcome, while Kalshi markets focus on progression in the EFL Cup tie, creating a scope difference.Hero tip: Treat Polymarket and Kalshi markets as separate predictions. A West Ham win in the first match doesn't guarantee a 'Yes' on the Kalshi 'West Ham Advance' market.

Critical divergence points:

  • Polymarket: Resolves based on the result of the single match on September 15, 2026, determining a winner or draw within 90 minutes + stoppage time. Uses official statistics, with Flashscore/Sofascore as fallbacks.
  • Kalshi: Resolves based on which team advances in the EFL Cup tie, implying a multi-stage competition. The specific rules for advancement (e.g., aggregate score, away goals) are not specified in the provided information.
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.

Frequently asked questions

Prediction market odds, like those found on Polymarket and Kalshi, often differ from traditional sportsbook odds due to the wisdom of the crowd and incentive structures. Sportsbooks set lines to balance their risk and ensure profit, while prediction markets allow participants to directly express their beliefs. This can lead to more accurate probabilities, especially as more information emerges. The volume of $1,044,678 traded on this market suggests a significant level of interest and informed participation. It’s common to see discrepancies, particularly before the event, as differing information and analyses are weighed by market participants.

Prices on Polymarket and Kalshi for the West Ham vs. Fulham match can diverge due to several factors. 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 has a unique user base with varying levels of expertise and access to information, leading to different interpretations of the likely outcome. Trading mechanisms and fee structures also contribute to price discrepancies. Furthermore, liquidity – reflected in the trading volume of $1,044,678 – can be unevenly distributed between the platforms, impacting price discovery. These differences are a natural part of a decentralized market and provide opportunities for arbitrage.
