This event tracks the lowest temperature recorded in Chicago on a specific date in the future, using data from a designated weather provider. The outcome depends on where the temperature falls within predefined ranges, offering various possibilities for how cold the city will be on that day.
All markets resolve based on the minimum temperature recorded at Chicago's CLIMDW station on September 18, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: 59°F or below, 60-61°F, 62-63°F, 64-65°F, 66-67°F, or 68°F and above. The Exchange may delay resolution if it identifies a material error in the initial data publication, allowing time for a corrected report or proceeding to the Expiration Date. If no data remains available by then, markets resolve at the last fair price determined by Kalshi. Preliminary data may differ from final values due to rounding or conversion, and the 'Final' status on weather.com/kalshi is informational only and does not guarantee accuracy.
