This market tracks whether the Cincinnati Reds and Seattle Mariners baseball game scheduled for July 22, 2026 at 3:40 PM EDT extends beyond nine innings. Extra innings occur when the score remains tied after regulation play.
If Cincinnati and Seattle go to extra innings in the Cincinnati vs Seattle professional baseball game originally scheduled for Jul 22, 2026 at 3:40 PM EDT, then the market resolves to Yes.
Prediction market odds and sportsbook odds often diverge because they serve different purposes and operate under different constraints. Sportsbooks set odds to balance their book and manage risk, while prediction markets aggregate trader beliefs through continuous price discovery. This market may show different probabilities than traditional sportsbooks because traders here are directly wagering on their conviction, without the sportsbook's built-in margin. Comparing the two can reveal where market participants see value relative to conventional betting lines.
On Kalshi, this market is priced through an order-book mechanism where buyers and sellers submit bids and asks, and trades execute when orders match. On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. The price reflects the marginal agreement between the last buyer and seller, moving up or down as new information or sentiment shifts. Traders can enter or exit positions at any time before the market closes, and the final price at settlement represents the market's aggregate belief about whether extra innings will occur.
This market resolves around Jul 22, 2026, once the Cincinnati versus Seattle game concludes and the final result is verifiable. The outcome will be confirmed against credible public sources reporting whether the game went to extra innings. Until that time, traders can continue to buy and sell positions as new developments emerge, including team news, weather updates, or live game action that might shift expectations about the likelihood of an extended contest.
Several factors could shift odds in this market before resolution. Roster changes, injuries to key players, or lineup announcements may alter perceptions of team strength and game competitiveness. Weather conditions at game time—wind, temperature, or humidity—can influence scoring pace and the likelihood of a close contest. Live game developments, such as early scoring trends, pitching changes, or momentum swings, will likely drive substantial price movement as traders update their expectations based on real-time action and the evolving probability of extra innings.
