This event tracks the highest temperature reached in Chicago on August 4, 2026, using official National Weather Service data. Participants assess temperature ranges to determine the outcome, with precise reporting standards ensuring consistency.
The event resolves based on the highest temperature recorded at Chicago Midway, IL on August 04, 2026, as reported by the National Weather Service's Climatological Report (Daily). Six distinct temperature range markets exist: 80° or below, 81-82°, 83-84°, 85-86°, 87-88°, and 89° or above. The market corresponding to the actual recorded temperature range will resolve to Yes, with all others resolving to No. The official NWS report is the sole source for determining the outcome, and traders must recognize that preliminary data may be subject to rounding or conversion adjustments. All secondary rules emphasize reliance on the linked NWS report over alternative weather services to maintain uniformity in resolution.
