Description

This event tracks whether Phoenix will experience specific temperature ranges on a particular day in 2026. The outcome depends entirely on official weather data from a designated source, reflecting real-world interest in extreme heat conditions.

Kalshi

All markets resolve based on the maximum temperature recorded in Phoenix (CLIPHX) on September 19, 2026, as reported by The Weather Company. Each market corresponds to a distinct temperature range: less than 99°F, 99–100°F, 101–102°F, 103–104°F, 105–106°F, or above 106°F. The Exchange holds expiration if a material error is identified in the initial data publication, resolving markets to the last fair price if no valid data exists by the expiration date. Preliminary data may differ from final values due to rounding or conversion, and the 'Final' status on weather.com/kalshi is informational only. All resolutions rely solely on The Weather Company's official report.
