Detroit and Kansas City battle in a game that might not conclude within the usual nine-inning timeframe. Should the teams remain locked in a stalemate after the ninth inning, extra innings will be played until one team gains the upper hand.
If Detroit and Kansas City go to extra innings in the Detroit vs Kansas City professional baseball game originally scheduled for Aug 22, 2026 at 7:15 PM EDT, then the market resolves to Yes.
Prediction market odds often differ from traditional sportsbook lines due to trader dynamics and real-time adjustments. In this market, prediction odds reflect aggregated trader beliefs about the probability of extra innings, which can be more volatile than sportsbook odds set by professional oddsmakers. Traders may react faster to new information, causing prediction odds to shift more quickly than sportsbook lines, which are typically adjusted less frequently.
On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. On Kalshi, traders actively set the price through buying and selling contracts, with the current odds reflecting the collective assessment of market participants. The top outcome's chance is displayed as a percentage, derived from the trading volume and order book depth. This continuous pricing mechanism allows for rapid adjustments based on new information or shifts in trader sentiment leading up to the event.
This market resolves around Aug 23, 2026, with the outcome confirmed once the event is verifiable from credible public reporting. The result is determined by whether the game extends past the scheduled nine innings, as reflected in official game records and post-game summaries.
Injuries to key players, weather delays, or changes in starting pitchers can all influence this market as the game nears. Any development affecting the pace or length of the match — such as a dominant pitcher entering the game or a high-scoring first half — may shift trader expectations. News reports, pre-game analysis, and last-minute lineup changes often drive volume and price movements in the weeks before Aug 23, 2026.
