Description

This event tracks the lowest temperature recorded in Chicago on a specific date in the future, using official government data as the definitive source. Participants assess weather conditions and historical trends to predict the outcome.

Kalshi

The event determines the resolution based on the minimum temperature recorded in Chicago on July 29, 2026, as reported by the National Weather Service's Climatological Report (Daily). Six distinct temperature ranges are defined, each corresponding to a different market outcome. If the recorded minimum temperature falls within a specific range, the associated market resolves to Yes; otherwise, it resolves to No. All outcomes rely exclusively on the official NWS data for accuracy, with secondary sources serving only as reference. Traders must use the latest available NWS report for the date, noting that data updates may occur at varying frequencies across different locations. Preliminary data may contain rounding or conversion discrepancies, so caution is advised when interpreting such information. The final determination will strictly follow the NWS report to ensure consistency and reliability.
