Description

This event tracks the highest temperature reached in Chicago on a specific date in the future, using data from a designated weather provider. The outcome depends on whether the temperature falls within certain predefined ranges.

Kalshi

The event resolves based on the maximum temperature recorded in Chicago (CLIMDW) on September 9, 2026, as reported by The Weather Company. Six separate markets correspond to different temperature ranges: less than 80°F, 80-81°F, 82-83°F, 84-85°F, 86-87°F, and greater than 87°F. If the temperature falls within a specific range, the corresponding market resolves to Yes, with all others resolving to No. Preliminary data may be subject to rounding or conversion differences, and the Exchange reserves the right to delay resolution if a material error is identified in the initial publication. If no data is available by the expiration date, markets will resolve to the last fair price determined by the Exchange. The status of 'Final' on The Weather Company's platform is for convenience and does not guarantee data accuracy or exempt the event from potential revisions.
