Description

This event tracks the highest temperature reached in Chicago on a specific date in the future. It categorizes possible temperature ranges to determine the outcome based on official meteorological data. The event uses a single authoritative source to ensure consistency and accuracy in measurement.

Kalshi

The event resolves based on the maximum temperature recorded in Chicago (CLIMDW) on August 23, 2026, as reported by The Weather Company. Six distinct temperature ranges are defined: 73° or below, 74° to 75°, 76° to 77°, 78° to 79°, 80° to 81°, and 82° or above. If the recorded temperature falls within any of these ranges, the corresponding market resolves to Yes. All outcomes rely exclusively on The Weather Company's official reporting, with participants advised that preliminary data may vary due to rounding or conversion differences. This single-source verification ensures clarity and eliminates ambiguity from disparate weather data interpretations.
