This set of markets focuses on predicting Chicago's lowest temperature on a specific future date. Outcomes depend entirely on official weather data from a designated source, with markets covering different temperature ranges to capture various possible scenarios.
All markets resolve based on the minimum temperature recorded in Chicago (CLIMDW) on October 5, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: below 43°F, 43-44°F, 45-46°F, 47-48°F, 49-50°F, or above 50°F. The Exchange reserves the right to delay resolution if it identifies material errors in the initial data publication, extending this until a corrected version is released or the expiration date arrives. Should final data remain unavailable by the expiration date, all markets resolve at the last fair price determined by Kalshi. While other weather services may show different values, The Weather Company's report is the sole authority for resolution.
