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 solely on the recorded maximum temperature for that day, with different markets covering various temperature ranges.
All markets resolve based on the maximum temperature recorded at Chicago's CLIMDW station on October 5, 2026, as reported by The Weather Company. Each market covers a specific temperature range: 63°F or below, 64-65°F, 66-67°F, 68-69°F, 70-71°F, or above 71°F. The Exchange may delay resolution if it identifies a material error in the initial data publication, extending until a corrected version is released or the expiration date passes. If data remains unavailable by the expiration date, markets resolve at the last fair price determined by Kalshi. While other weather sources may show different values, only The Weather Company's official report determines the outcome. Preliminary data may differ from final values due to rounding or conversion, so participants should exercise caution when interpreting early readings. The 'Final' status on weather.com/kalshi is informational only and does not guarantee data accuracy or exempt markets from potential resolution adjustments.
