Description

This event tracks the lowest temperature recorded in Chicago on a specific date in the future, helping participants gauge climate conditions and temperature trends for that day. The outcome depends solely on official weather data from a designated source.

Kalshi

The event resolves based on the minimum temperature recorded at Chicago’s CLIMDW station on August 31, 2026, as reported by The Weather Company. Six distinct temperature ranges define the possible outcomes, each corresponding to a specific market resolution. If the minimum temperature falls below 67°F, the lowest range market resolves positively. If it falls between 67°F and 68°F, the next market resolves positively, and this pattern continues through successive two-degree increments up to 74°F. Any temperature above 74°F triggers the highest range market. All markets rely exclusively on The Weather Company’s final reported values, with participants advised to exercise caution when interpreting preliminary or third-party data due to potential rounding or conversion discrepancies.
