Description

This event tracks the lowest temperature recorded in Chicago on a specific date, using official government data as the sole source for verification. Participants assess whether conditions will fall within particular temperature ranges based on authoritative meteorological reports.

Kalshi

All markets resolve based solely on the official minimum temperature recorded at Chicago - Midway, IL on August 1, 2026, as reported in the National Weather Service's Climatological Report (Daily). Each market corresponds to a specific temperature range: 61°F or below, 62-63°F, 64-65°F, 66-67°F, 68-69°F, or 70°F and above. The exact temperature value determines which market resolves to 'Yes,' with all others resolving to 'No.' Traders must reference the official NWS data linked in the rules, as preliminary or third-party weather sources are not considered valid for resolution. Due to potential rounding and conversion nuances in preliminary NWS data, caution is advised when interpreting early reports. The most recent, finalized version of the Climatological Report for the specified date is the definitive source for all outcomes.
