This event tracks the highest temperature reached 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, reflecting possible weather conditions for that day.
All markets resolve based on the maximum temperature recorded at Chicago (CLIMDW) on October 7, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: 73°F or below, 74-75°F, 76-77°F, 78-79°F, 80-81°F, or above 81°F. The Weather Company’s data is the sole authority for resolution. Preliminary data may differ from final values due to rounding or conversion issues, so users should exercise caution. If the Exchange identifies a material error in the initial data before expiration, it may delay resolution until a corrected version is published or until the expiration date. If data remains unavailable by expiration, markets resolve to the last fair price determined by Kalshi. The "Final" status on The Weather Company’s platform is informational and does not guarantee error-free data.
