Description

This event tracks the actual peak temperature in Chicago on a specific future date, using official government data as the definitive source. Participants assess likelihoods based on historical trends, seasonal patterns, and long-range forecasts. The outcome hinges solely on the exact numerical reading from the designated weather agency's report for that day.

Kalshi

All markets resolve based exclusively on the highest temperature recorded at Chicago Midway, IL on July 23, 2026, as reported in the National Weather Service's official Climatological Report (Daily). Each market corresponds to a specific temperature range: 75° or below, 76-77°, 78-79°, 80-81°, 82-83°, or above 83°. If the recorded temperature falls within a market's defined range, that market resolves to Yes; all others resolve to No. Traders must rely solely on the NWS report for resolution, as preliminary or third-party data sources are not authoritative. Due to potential rounding and conversion nuances in preliminary NWS data, caution is advised when interpreting early reports. The final NWS Climatological Report serves as the binding authority for all outcomes.
