PredictionHero - Resolution Divergence Alerts (RDA)

Divergence Detected

Issue: Cancellation handling differs between platforms. Polymarket explicitly resolves 'No' if the game is canceled, while Kalshi lacks a defined resolution for this scenario.Hero tip: Consider the likelihood of game cancellation when trading on Kalshi, as a canceled game may lead to ambiguity or a less favorable outcome than on Polymarket.

Critical divergence points:

  • Polymarket: Markets resolve based on the outcome within 90 minutes plus stoppage time. If the game is canceled entirely with no make-up game, the market resolves to 'No'. "If the game is canceled entirely, with no make-up game, this market will resolve 'No'."
  • Kalshi: Markets resolve based on the outcome within 90 minutes plus stoppage time. No explicit mention of resolution in the event of cancellation. "If Tie is the result...then the market resolves to Yes."

Frequently asked questions

Prediction market odds, like those found for this market, often differ from traditional sportsbook odds due to the underlying mechanisms. Sportsbooks set odds to ensure profitability, incorporating a margin, while prediction markets are driven by genuine user belief. This can lead to more accurate probabilities, as traders are incentivized to bet based on their best assessment. However, sportsbook odds can influence prediction market prices, and vice versa, creating a dynamic interplay. Furthermore, the volume traded on prediction markets can be significantly lower than that of sportsbooks, potentially leading to greater price volatility in this market.

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. The differing prices on Polymarket and Kalshi for the FC Groningen vs. Ajax match can stem from several factors. Each platform attracts a different user base with varying expertise and information. Trading fees and platform-specific rules can also influence pricing. Additionally, the liquidity on each platform—reflected in the trading volume—plays a role; lower volume can lead to wider spreads. Finally, differing interpretations of available information about team form, injuries, and other relevant factors can contribute to the observed price discrepancies between these two venues.
