Description

The event tracks the peak temperature in Chicago on a specific summer day in 2026. Outcomes depend on how high the temperature climbs, with different ranges determining success.

Kalshi

The event resolves based on the maximum temperature recorded at Chicago's CLIMDW station on August 25, 2026, as reported by The Weather Company. Six temperature ranges are defined: 77°F or below, 78-79°F, 80-81°F, 82-83°F, 84-85°F, and 86°F or above. If the recorded temperature falls within any of these ranges, the corresponding market resolves to Yes. All outcomes use The Weather Company's official reporting as the sole source, with users cautioned that preliminary data may vary due to rounding or conversion differences.
