Intro

This market tracks the probability of the Tampa Bay Rays covering a -9.5 spread against the Athletics in their upcoming baseball game. Currently, the consensus probability across Polymarket, Kalshi, and Predict is 10.0%. Resolution will be based on the official results reported at https://www.mlb.com/scores. However, traders should be aware of the date discrepancy between platforms – Kalshi resolves to a game scheduled for September 17, 2026, while Polymarket and Predict resolve to the game scheduled for September 17, 2024 – and monitor the outcome of the September 17, 2024 game to see how the market resolves on those platforms.

PredictionHero - Resolution Divergence Alerts (RDA)

Divergence Detected

Issue: Kalshi references a game in 2026, while Polymarket and Predict reference a game in 2024.Hero tip: Exercise extreme caution when trading. Ensure you understand which date each market is referencing before making any decisions. The Kalshi market is effectively a different event.

Critical divergence points:

  • Polymarket: Resolves to Athletics or Tampa Bay Rays based on the outcome of the game on September 17, 2024. 'If the game is postponed, this market will remain open until the game has been completed. If the game is canceled entirely, with no make-up game, or ends in a tie, this market will resolve 50-50.'
  • Predict: Resolves to Athletics or Tampa Bay Rays based on the outcome of the game on September 17, 2024. 'If the game is postponed, this market will remain open until the game has been completed. If the game is canceled entirely, with no make-up game, or ends in a tie, this market will resolve 50-50.'
  • Kalshi: Resolves to Yes if either team wins the game originally scheduled for September 17, 2026. This market appears to be structured as two separate 'Yes' markets, one for each team winning.
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.

In the upcoming MLB game between the Athletics and Tampa Bay Rays, scheduled for September 17 at 1:10PM ET: This market will resolve to "Athletics" if the Athletics win the game.
