Description

This event tracks the highest temperature reached in Chicago on a specific date in the future, using data from a designated weather authority. It helps participants assess climate conditions and temperature trends for that exact day. The outcome depends solely on the official temperature recording from the chosen source.

Kalshi

The event resolves based on the maximum temperature recorded in Chicago (CLIMDW) on August 29, 2026, as reported by The Weather Company. Six distinct temperature ranges define the possible outcomes: 79°F or below, 80-81°F, 82-83°F, 84-85°F, 86-87°F, and 88°F or above. Each market corresponds to one of these ranges, and the market resolves to Yes if the recorded temperature falls within its specified range. All participants must rely exclusively on The Weather Company's official report for resolution, as preliminary data from other sources may vary due to rounding or conversion differences. The final reported value from The Weather Company is definitive, regardless of discrepancies with other weather services.
