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 where the temperature falls within predefined ranges, reflecting possible weather conditions for that day.

Kalshi

The event resolves based on the maximum temperature recorded in Chicago (CLIMDW) on September 5, 2026, as reported by The Weather Company. Six distinct temperature ranges are defined, each corresponding to a separate market outcome. If the temperature falls within a specific range, the associated market resolves to Yes, while all others resolve to No. All markets share identical secondary rules regarding data verification and error handling. Preliminary data may be subject to rounding or conversion differences, and The Weather Company’s final reported value is the official determinant. If a material error is identified in the initial publication before the expiration date, the resolution may be delayed until a corrected value is published or until the expiration date arrives. If no valid data exists at expiration, all markets resolve to the last fair price determined by the exchange. The "Final" status on The Weather Company’s platform is informational only and does not guarantee data accuracy or exempt the data from potential revision under these rules.
