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 the likelihood of different temperature ranges based on historical patterns and forecasts.

Kalshi

All markets resolve based solely on the official minimum temperature recorded in Chicago on July 23, 2026, as reported by the National Weather Service's Climatological Report (Daily) for Chicago - Midway, IL. The outcome is determined by comparing this official figure against predefined temperature ranges: below 55°F, 55-56°F, 57-58°F, 59-60°F, 61-62°F, or above 62°F. Traders must rely exclusively on the NWS data linked in the rules, as preliminary or third-party reports are not considered authoritative. Due to potential rounding and conversion nuances in NWS reporting, caution is advised when interpreting early or unofficial data. The latest available NWS report for the date will be used as the final arbiter.
