Description

This event tracks the lowest temperature recorded in Chicago on a specific date, using official government data as the sole source for verification. Participants assess whether conditions will fall within certain temperature ranges based on authoritative meteorological reports.

Kalshi

All markets resolve based solely on the official minimum temperature recorded at Chicago - Midway, IL on August 13, 2026, as reported in the National Weather Service's Climatological Report (Daily). The outcome is determined by comparing this single temperature value against predefined ranges: below 64°F, 64-65°F, 66-67°F, 68-69°F, 70-71°F, or above 71°F. Traders must rely exclusively on the NWS report available at https://www.weather.gov/wrh/Climate?wfo=lot under the 'Observed Weather' tab with Daily Climate Report selected, using the latest version published after the date in question. While third-party weather services may provide guidance, they hold no resolving authority—only the NWS data determines the market outcome. Participants should remain alert to potential rounding differences and reporting delays inherent in meteorological data compilation.
