Description

This event tracks the highest temperature reached in Phoenix on a specific date in the future, using data from a designated weather authority. Participants can assess various temperature ranges to predict extreme heat conditions. The outcome depends solely on the official temperature recording from the chosen source.

Kalshi

The event determines the outcome based on the maximum temperature recorded in Phoenix (CLIPHX) on August 19, 2026, as reported by The Weather Company. Six distinct temperature ranges are defined, each corresponding to a specific market resolution. If the temperature falls within any of these ranges, the associated market resolves to Yes. All markets rely exclusively on The Weather Company's data for final determination, ensuring consistency despite variations in other weather sources. The ranges progress from temperatures of 106°F or below up to 115°F or above, covering a spectrum of potential heat levels for that day.
