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, reflecting varying levels of warmth on that day.

Kalshi

The event resolves based on the maximum temperature recorded in Chicago (CLIMDW) on October 18, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: 60°F or below, 61°F to 62°F, 63°F to 64°F, 65°F to 66°F, 67°F to 68°F, or 69°F or above. The market associated with the actual recorded temperature range will resolve to Yes, while all others resolve to No. All temperature data is subject to potential revisions if material errors are identified by the Exchange, in which case expiration may be extended until a corrected value is published or the expiration date arrives. If data remains unavailable by the expiration date, markets resolve to the last fair price determined by the Exchange. The status of 'Final' on The Weather Company's platform does not guarantee immunity from such revisions.
