Description

This set of markets assesses the likelihood of specific temperature ranges in Denver on September 18, 2026. Outcomes depend on the actual high temperature recorded that day, categorized into distinct bands from very cool to exceptionally hot conditions.

Kalshi

All markets resolve based on the maximum temperature recorded in Denver (CLIDEN) on September 18, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: 77°F or below, 78-79°F, 80-81°F, 82-83°F, 84-85°F, or above 85°F. The Weather Company’s data is the sole authority for resolution. Preliminary readings may differ from final values due to rounding or conversion issues, so participants should exercise caution. If the Exchange identifies a material error in the initial data before expiration, it may delay resolution until a corrected value is published or until the expiration date. If no valid data exists by expiration, markets resolve to the last fair price determined by Kalshi. The "Final" status on Weather Company platforms is informational only and does not guarantee error-free data.
