This set of markets focuses on predicting Chicago's weather conditions for a specific date in the future. Participants assess the likelihood of different temperature ranges being reached, based on data from a designated weather authority. The outcomes depend solely on the officially recorded maximum temperature for that day.
These markets resolve based on the maximum temperature recorded in Chicago (CLIMDW) on October 2, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: 60°F or below, 61°F to 62°F, 63°F to 64°F, 65°F to 66°F, 67°F to 68°F, and 69°F or above. If the recorded temperature falls within a market's specified range, that market resolves to Yes; otherwise, it resolves to No. All markets share identical secondary rules regarding data verification and error handling. Preliminary Weather Company data may be subject to rounding or conversion differences, and the Exchange reserves the right to delay expiration if a material error is identified in the initial publication. If data remains unavailable by the expiration date, markets will resolve to the last fair price determined by Kalshi. The status of 'Final' on weather.com/kalshi is informational only and does not guarantee data accuracy or exempt markets from these procedures.
