Description

This event tracks the lowest temperature recorded in Chicago on a specific future date, using official meteorological data. Participants assess whether conditions will fall within certain temperature ranges based on authoritative sources.

Kalshi

All markets resolve based solely on the official minimum temperature recorded in Chicago on August 3, 2026, as reported by the National Weather Service's Climatological Report (Daily) for Chicago - Midway, IL. Each market corresponds to a specific temperature range: below 58°F, 58-59°F, 60-61°F, 62-63°F, 64-65°F, or above 65°F. The final determination uses the latest official NWS data available after the date in question. Traders must rely exclusively on these reports, as preliminary or third-party data sources may differ due to rounding, conversion, or timing variances in reporting. All outcomes are mutually exclusive and collectively exhaustive, with exactly one market resolving to Yes based on where the actual recorded low falls within the defined ranges.
