Both markets share common postponement and cancellation rules but differ in their specific resolution outcomes.
In the upcoming MLB game between the St. Louis Cardinals and Atlanta Braves, scheduled for July 1 at 7:15PM ET: This market will resolve to "St. Louis Cardinals" if the St. Louis Cardinals win the game.

If the game is canceled entirely, with no make-up game, or ends in a tie, this market will resolve 50-50. The primary resolution source for this market is the official final statistics of the event as recognized by the governing body or event organizers. However, if the governing body or event organizers have not published final match statistics within 24 hours after the event's conclusion, a consensus of credible reporting may be used instead.

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 attracts distinct trader demographics, liquidity pools, and fee structures that influence how prices settle. Polymarket and Kalshi may also have different contract specifications—for example, one might focus on the full-game outcome while the other tracks first-inning scoring or run differential. Regulatory frameworks and market-making incentives vary too, meaning arbitrage opportunities can persist between venues. Monitoring both helps you identify whether price gaps reflect genuine disagreement or temporary inefficiencies worth exploiting.
Key catalysts include roster changes, injury announcements, recent team performance trends, and head-to-head historical matchups. Weather conditions, home-field advantage, and bullpen availability often shift trader positioning closer to game time. Breaking news about player availability or lineup decisions can trigger sharp repricing. Additionally, movement in related markets—such as run-total or inning-specific props—may signal informed traders adjusting their view of the overall outcome. Monitor sports news feeds and platform activity to catch early signals before this market fully reprices.
