This set of markets focuses on predicting Chicago's weather conditions for a specific date in the future. Each market corresponds to a different temperature range, allowing participants to bet on where the actual high temperature will fall. The outcome depends entirely on official weather data from a designated source.
All markets resolve based on the maximum temperature recorded in Chicago (CLIMDW) on November 2, 2026, as reported by The Weather Company. Each market covers a specific temperature range, with one market for temperatures 63°F or below, incremental ranges up to 71°F, and a final market for temperatures above 71°F. The Weather Company serves as the sole authority for temperature data. Preliminary readings may differ from final values due to rounding or conversion issues. If the Exchange identifies a material error in the initial data publication, it may delay resolution until a corrected version is released or until the expiration date. If data remains unavailable by the expiration date, markets resolve to the last fair price determined by Kalshi. The 'Final' status on weather.com/kalshi is informational only and does not guarantee data accuracy or exempt markets from potential revisions.
