Description

This event tracks the lowest temperature recorded in Chicago on a specific future date, using official government data sources. The outcome depends entirely on the exact temperature reading reported after the fact, making it a straightforward test of weather conditions against predefined thresholds.

Kalshi

All markets resolve based solely on the official minimum temperature recorded for Chicago on July 24, 2026, as reported in the National Weather Service's Climatological Report (Daily) for Chicago - Midway, IL. Each market corresponds to a specific temperature range: 57°F or below, 58-59°F, 60-61°F, 62-63°F, 64-65°F, or 66°F and above. Only the market matching the exact reported temperature range will resolve to Yes; all others resolve to No. Traders must reference the official NWS data linked in the rules, as preliminary or third-party weather sources are not authoritative for resolution purposes. It is important to note that NWS data may undergo revisions after initial reporting, and traders should use the latest available version of the Climatological Report for the specified date when assessing outcomes. Rounding and conversion nuances in the reporting process may affect which range a borderline temperature falls into, so caution is advised when interpreting early or unofficial data.
