This event tracks the highest temperature reached in Chicago on a specific date in the future. The outcome depends entirely on official weather data from a designated source, reflecting real-world climate conditions for that day.
The event resolves based on the maximum temperature recorded in Chicago on August 14, 2026, as reported by The Weather Company. Six distinct temperature ranges are defined, each corresponding to a separate market outcome. If the temperature falls within a specific range, the associated market resolves to Yes; all others resolve to No. The official data source is accessible via The Weather Company’s Observed Weather tab for Chicago - Midway, IL, using the Daily Climate Report. Participants should verify that they are using the latest data version, as update frequencies may vary across locations. While alternative weather services may offer similar data, The Weather Company’s report is the sole authority for resolution. This structure ensures an objective, data-driven determination of the event’s outcome based on actual climatic conditions.
