Kalshi
An extra inning occurs in a professional baseball game when the regulation nine innings end with the score tied, leading to additional innings until a winner is determined. This particular game was scheduled for a specific date and time, and the extension beyond the standard duration would be required for a resolution based on certain conditions. Such occurrences are common in baseball when teams remain evenly matched through the initial playing period.
If at least 1 extra inning is played in the St. Louis vs Los Angeles D professional baseball game originally scheduled for Sep 1, 2026 at 10:10 PM EDT, then the market resolves to Yes.
On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. On Kalshi, traders determine prices through continuous trading, with the current top outcome reflecting the majority sentiment. The chance percentage displayed represents the market’s implied probability of extra innings occurring, adjusted for liquidity and trader positions. As new information surfaces — such as pitcher changes or weather updates — participants can buy or sell contracts, shifting the odds dynamically.
This market resolves around Sep 2, 2026, with the outcome confirmed once the event is verifiable from credible public reporting. The result is determined by whether the game lasts longer than nine innings, as officially recorded by the league. Once the game concludes, the market settles based on this verified result, and all contracts are closed accordingly.
Several signals could shift this market before it resolves. Key factors include starting pitcher announcements, weather forecasts that might delay or extend gameplay, and in-game performance updates as the match progresses. Any news affecting the teams’ strategies or game length — such as injuries or managerial decisions — may also influence trader sentiment and move the odds on Kalshi closer to resolution.
