Description

This event tracks whether Phoenix will reach specific temperature thresholds on a particular date in 2026. Outcomes depend on official weather data from a designated source, reflecting potential climate conditions and variability.

Kalshi

All markets resolve based on the maximum temperature recorded in Phoenix (CLIPHX) on September 18, 2026, as reported by The Weather Company. Each market corresponds to a distinct temperature range: 97°F or below, 98-99°F, 100-101°F, 102-103°F, 104-105°F, or above 105°F. The official data source is The Weather Company, and while other weather services may provide similar data, they are not used for resolution. Preliminary data may be subject to rounding or conversion differences, so participants should exercise caution. If the Exchange identifies a material error in the initial data publication, it may delay expiration until a corrected version is released or until the expiration date, whichever comes first. If no data remains available by the expiration date, all markets resolve to the last fair price determined by Kalshi. The "Final" status on weather.com/kalshi is for convenience and does not guarantee data accuracy or exempt markets from potential corrections.
