Highest temperature in Chicago on Oct 27, 2026?

Kalshi

The event resolves based on the maximum temperature recorded in Chicago (CLIMDW) on October 27, 2026, as reported by The Weather Company. Six distinct temperature ranges are defined, each corresponding to a separate market that will resolve to 'Yes' if the recorded temperature falls within that range. All markets share common secondary rules regarding data verification and error handling. If The Weather Company’s initial report contains a material error, the exchange may delay resolution until a corrected version is published or until the expiration date. If data remains unavailable by the expiration date, markets will resolve to the last fair price determined by Kalshi. The 'Final' status on The Weather Company’s platform is informational only and does not guarantee data accuracy or exempt the event from these error-resolution procedures.
