Description

This event tracks the highest temperature recorded at Chicago Midway, Illinois on July 17, 2026. The outcome will be determined by the National Weather Service's official Climatological Report (Daily) for that date, with temperature ranges spanning from 88°F or below up to 97°F or above.

Kalshi

Resolution is based on the highest temperature recorded at Chicago Midway, Illinois on July 17, 2026, as reported in the National Weather Service's Climatological Report (Daily). The temperature is divided into six distinct ranges: 88°F or below, 89–90°F, 91–92°F, 93–94°F, 95–96°F, and 97°F or above. Each range corresponds to a separate market outcome that resolves to Yes if the recorded temperature falls within that range. The NWS Climatological Report (Daily) serves as the sole authoritative source for resolution; preliminary NWS data and alternative weather services such as AccuWeather or Google Weather may be consulted for guidance but are not binding. Traders should be aware that preliminary NWS reporting and measurement methods may involve rounding and conversion nuances that could affect interpretation of data.
