This event tracks the maximum temperature expected in Chicago on a specific future date, using data from a designated weather provider. Participants can assess various temperature ranges to predict weather conditions for that day. The outcome depends solely on the official temperature recording from the chosen source.
The event determines whether the maximum temperature in Chicago on October 24, 2026, falls within specific Fahrenheit ranges, as recorded by The Weather Company at the CLIMDW station. Each market corresponds to a distinct temperature band: below 68°F, 68–69°F, 70–71°F, 72–73°F, 74–75°F, or above 75°F. The Weather Company’s reported maximum temperature serves as the definitive measure for resolution. All markets share consistent secondary rules regarding data interpretation and error handling. Preliminary data may undergo rounding or conversion adjustments, and users should exercise caution when evaluating early readings. If the Exchange identifies a material error in the initially published data before the market’s expiration, it may delay resolution until a corrected version is released or until the expiration date arrives, whichever occurs first. Should no reliable data remain available by the expiration date, all markets resolve based on the last fair price established by Kalshi. Importantly, a “Final” status on The Weather Company’s platform is informational only and does not shield the data from potential revisions under these rules.
