Description

Chicago’s climate on August 21, 2026 will be categorized into six temperature bands, each governing a unique market result through peak temperature data from an official source.

Kalshi

The outcome of each market is determined by the maximum temperature recorded at Chicago (CLIMDW) on August 21, 2026, as reported by The Weather Company. Six temperature ranges apply: 77° or below, 78° to 79°, 80° to 81°, 82° to 83°, 84° to 85°, and 86° or above. The secondary rule emphasizes that The Weather Company’s data is the authoritative source for resolution, even though other weather services may be referenced for supplementary information.
