Description

This event tracks whether Chicago will experience specific temperature ranges on a particular day in the future. The outcome depends entirely on official weather data from a designated source, reflecting potential interest in climate patterns and extreme weather planning.

Kalshi

All markets resolve based on the maximum temperature recorded in Chicago (CLIMDW) on September 12, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: below 84°F, 84-85°F, 86-87°F, 88-89°F, 90-91°F, or above 91°F. The Exchange holds expiration if a material error is identified in the initial data publication, resolving markets to the last fair price if no valid data exists by the expiration date. Preliminary data may differ from final values due to rounding or conversion, and the 'Final' status on weather.com/kalshi is informational only. All resolutions rely exclusively on The Weather Company's official reporting.
