This event tracks the lowest temperature recorded in Chicago on a specific date in 2026. Outcomes depend on where the minimum temperature falls within predefined ranges, using official government data as the source.
All outcomes are determined exclusively by the minimum temperature recorded in Chicago on July 28, 2026, as reported by the National Weather Service's Climatological Report (Daily) for Chicago - Midway, IL. The market resolves to Yes for the outcome corresponding to the exact temperature range in which the official NWS minimum falls: below 64°F, between 64-65°F, between 66-67°F, between 68-69°F, between 70-71°F, or above 71°F. Traders must use the official NWS data linked in the rules, as preliminary or third-party reports may differ due to rounding or conversion variances. The latest available NWS report for the date should be used, acknowledging potential delays in official reporting across different locations.
