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 July 27, 2026, as reported in the National Weather Service's Climatological Report (Daily). The outcome is determined by comparing this single recorded value against predefined temperature thresholds: below 70°F, 70-71°F, 72-73°F, 74-75°F, 76-77°F, or above 77°F. Traders must rely exclusively on the NWS report available at the specified URL after the event date, as preliminary or third-party data sources are not considered official for resolution purposes. All markets are mutually exclusive, with exactly one resolving to 'Yes' based on where the actual temperature falls within these ranges.
