Description

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

Kalshi

All markets resolve based solely on the official minimum temperature recorded for Chicago on August 12, 2026, as reported in the National Weather Service's Climatological Report (Daily) for Chicago - Midway, IL. The market with the matching temperature range wins; for example, if the temperature is 63°F or lower, the 63° or below market resolves to Yes, while all others resolve to No. Ranges are mutually exclusive and collectively exhaustive, covering every possible integer value from 63°F upward in one-degree increments, with the final market (72° or above) capturing all temperatures above 71°F. Traders must rely exclusively on the official NWS report linked in the rules, as preliminary or third-party data sources are not binding. Due to potential rounding and conversion nuances in preliminary reports, caution is advised when interpreting early data.
