Prediction market odds often reflect the collective wisdom of a diverse group of traders, potentially differing from those set by sportsbooks. Sportsbooks typically set initial odds to balance their risk, while this market allows traders to freely adjust prices based on their own analysis and information. It’s common to see discrepancies, especially as new information emerges or public sentiment shifts. Comparing the implied probability from this market to sportsbook odds can reveal where the crowd believes there is value or mispricing regarding the likelihood of extra innings.
On Kalshi, this market is priced through a continuous order book where traders buy and sell contracts representing the probability of extra innings. The price of a contract ranges from 0 to 100, representing the implied probability of the event occurring. As more traders buy contracts, the price increases, and vice versa. On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. This dynamic pricing mechanism allows the market to quickly incorporate new information and reflect the evolving expectations of participants regarding the A's versus Cleveland game.
This market resolves around Sep 20, 2026, with the outcome confirmed once the event is verifiable from credible public reporting.

Traders will be able to claim their winnings or fulfill their obligations following the official resolution of the game.
