PredictionHero - Resolution Divergence Alerts (RDA)

Divergence Detected

Issue: Kalshi's resolution condition of 'Yes' for either team winning is redundant and differs from the standard win/loss resolution logic on other platforms.Hero tip: Avoid Kalshi for this event as its resolution logic is atypical. Focus on Polymarket, Predict, and Opinion, which offer a straightforward win/loss prediction.

Critical divergence points:

  • Kalshi: Resolves to 'Yes' if either the St. Louis Cardinals or the Colorado Rockies win the game. "If St. Louis wins...then the market resolves to Yes. If Colorado wins...then the market resolves to Yes."
  • Polymarket: Resolves to 'St. Louis Cardinals' if they win, or 'Colorado Rockies' if they win. "This market will resolve to 'St. Louis Cardinals' if the St. Louis Cardinals win the game. This market will resolve to 'Colorado Rockies' if the Colorado Rockies win the game."
  • Predict: Resolves to 'St. Louis Cardinals' if they win, or 'Colorado Rockies' if they win. "This market will resolve to 'St. Louis Cardinals' if the St. Louis Cardinals win the game. This market will resolve to 'Colorado Rockies' if the Colorado Rockies win the game."
  • Opinion: Resolves to 'St.Louis Cardinals' if they win, or 'Colorado Rockies' if they win. "If the St.Louis Cardinals win, the market will resolve to 'St.Louis Cardinals'. If the Colorado Rockies win, the market will resolve to 'Colorado Rockies'."
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.

Prediction market odds often differ from traditional sportsbook odds, reflecting different information sources and participant motivations. Sportsbooks set lines to balance action and ensure profit, while prediction markets are driven by individuals wagering their own capital based on their beliefs. This can lead to prediction markets being more accurate, particularly when incorporating information not readily reflected in sportsbook lines. However, sportsbook odds are easily accessible and provide a useful benchmark for comparison. The efficiency of this market will be determined by how closely it tracks the true probability of each outcome as the game approaches.

Prices on Polymarket and Opinion can diverge due to several factors. Polymarket and Opinion 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 a different user base with varying risk appetites and information access. Trading volume also plays a role; a market with higher volume on one platform tends to have more efficient price discovery. Furthermore, the specific question framing on each platform—even if addressing the same underlying event—can influence how traders interpret and value the potential outcomes. These differences contribute to the observed price discrepancies for this market.
