Description

This event tracks the lowest temperature recorded in Chicago on a specific date in the future. The outcome depends on the exact temperature range observed, with different ranges leading to different results. The data source for determining the final result is a specific weather service.

Kalshi

The event resolves based on the minimum temperature recorded in Chicago (CLIMDW) on August 28, 2026, as reported by The Weather Company. Six distinct temperature ranges are defined, each corresponding to a different market outcome. If the minimum temperature is less than 59°F, the '58° or below' market resolves to Yes. If it falls between 59°F and 60°F, the '59° to 60°' market resolves to Yes, and so on for the ranges of 61-62°F, 63-64°F, and 65-66°F. If the temperature exceeds 66°F, the '67° or above' market resolves to Yes. The Weather Company’s reported values are definitive, even if preliminary data from other services may differ due to rounding or conversion discrepancies. Participants should exercise caution when interpreting early or unofficial readings, as only the final official report from The Weather Company determines the resolution.
