This event tracks the lowest temperature recorded in Chicago on a specific date in the future, using official government data sources. Participants assess weather conditions based on verified meteorological reports rather than personal observations or third-party forecasts.
All outcomes depend exclusively on the official minimum temperature recorded by the National Weather Service's Climatological Report (Daily) for Chicago on August 2, 2026, at the Chicago - Midway, IL location. The market resolves based on specific temperature ranges: below 60°F, 60-61°F, 62-63°F, 64-65°F, 66-67°F, or above 67°F. Traders must access the latest data from the provided NWS URL after the event date to determine the resolution. While preliminary or third-party weather data may offer guidance, only the final NWS report serves as the binding authority, and users should be aware that reporting methodologies may include rounding or conversion nuances that could affect interpretation.
