The probability listed represents the market's collective belief in a specific outcome occurring, based on the bets placed.

Polymarket prediction markets function by allowing users to bet on the outcome of future events. The probability of an event is determined by the total amount of money bet on each outcome. For example, if $100 is bet on outcome A and $10 is bet on outcome B, the implied probability for A is approximately 91% ($100 / ($100 + $10)) and for B is 9% ($10 / ($100 + $10)). When you resolve a market, the price of the winning shares reflects the payout. If you buy a share for $0.75 and it resolves to $1.00, you have made a $0.25 profit. If you buy a share for $0.75 and it resolves to $0.00, you have lost your initial investment.

This specific market is set to resolve on May 20, 2026. As this is a sports market, it is expected to resolve based on the official result of the St. Louis Cardinals vs. Athletics game.
