Highest temperature in Chicago on Sep 13, 2026?

Kalshi

The event resolves based on the maximum temperature recorded in Chicago (CLIMDW) on September 13, 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 identical secondary rules regarding data verification and error handling. The Exchange retains discretion to delay resolution if a material error is identified in the initial data publication, allowing time for correction or proceeding to 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 The Weather Company's platform is informational only and does not guarantee data accuracy or exempt markets from potential resolution adjustments.
