Highest temperature in Chicago on Oct 4, 2026?

Kalshi

The event resolves based on the maximum temperature recorded in Chicago (CLIMDW) on October 4, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: 69° or below, 70-71°, 72-73°, 74-75°, 76-77°, and 78° or above. The official data source is The Weather Company, and while other weather services may offer similar data, they are not used for resolution. Preliminary data may be subject to rounding or conversion differences, so users should exercise caution. If the Exchange identifies a material error in the initial data publication, it may delay expiration until a corrected version is released or until the expiration date, whichever comes first. If data remains unavailable by the expiration date, all markets will resolve to the last fair price determined by Kalshi. The "Final" status on weather.com/kalshi is for convenience and does not guarantee data accuracy or exempt the event from potential revisions.
