This aggregation combines data from Polymarket, Predict, Opinion, and Kalshi, with resolution based on data reported by https://www.mlb.com/. However, traders should be aware of a significant date discrepancy, as Kalshi resolves to a game scheduled for September 23, 2026, while other platforms resolve to the September 23, 2023 game; keep a close eye on any updates regarding the resolution of the September 23, 2023 contest.

PredictionHero - Resolution Divergence Alerts (RDA)

Divergence Detected

Issue: A significant date discrepancy exists between Kalshi (2026) and the other platforms (2023), creating fundamentally different markets.Hero tip: Avoid Kalshi unless you specifically want to bet on a game three years in the future. Focus on Polymarket, Predict, and Opinion for the September 23, 2023 game.

Critical divergence points:

  • Polymarket: Resolves to the winner of the game on September 23, 2023. If the game is postponed, the market remains open. Cancellation or a tie results in a 50-50 split. Source: MLB.com. "This market will resolve to 'Arizona Diamondbacks' if the Arizona Diamondbacks win the game."
  • Predict: Identical logic to Polymarket, resolving to the winner of the game on September 23, 2023, with the same postponement/cancellation/tie rules. Source: MLB.com. "This market will resolve to 'Arizona Diamondbacks' if the Arizona Diamondbacks win the game."
  • Opinion: Resolves to the winner of the game on September 23, 2023, based on the first officially published result from MLB.com. Postponement/cancellation/tie rules are consistent. "If the Arizona Diamondbacks win, the market will resolve to 'Arizona Diamondbacks'."
  • Kalshi: Resolves to 'Yes' if either team wins the game originally scheduled for September 23, 2026. This is a different event entirely. "If Arizona wins the Arizona vs Colorado professional baseball game originally scheduled for Sep 23, 2026 at 8:40 PM EDT, then the market resolves to Yes."
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.

Frequently asked questions

Prediction market odds, like those found on this market, often differ from traditional sportsbook odds due to the underlying mechanisms. Sportsbooks set lines to balance action and incorporate a profit margin, while prediction markets rely on the collective intelligence of traders. This can lead to prediction market prices being more accurate reflections of true probabilities, particularly as more information becomes available. However, sportsbook odds are readily accessible and often influence initial trading in prediction markets. It’s common to see arbitrage opportunities between the two, as traders attempt to profit from discrepancies in perceived value.

Polymarket and Predict 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 Predict may diverge due to several factors. Different user bases and trading volumes on each platform contribute to price discrepancies. Polymarket might attract more sophisticated traders, while Predict could have a broader range of participants with varying levels of expertise. Additionally, the specific rules and fee structures of each platform can influence trading behavior and, consequently, prices. Trading volume, even if similar, can be focused on different outcomes on each platform, leading to varied probabilities for the Diamondbacks-Rockies game.
