Description

This event tracks the highest temperature reached in Phoenix on a specific date in the future, using data from a designated weather authority. It helps participants assess climate conditions and temperature trends for that exact day. The outcome depends solely on the official temperature recording from the chosen source.

Kalshi

The event determines whether the maximum temperature in Phoenix on August 18, 2026, falls within specific Fahrenheit ranges, with resolution based exclusively on data from The Weather Company. Six distinct temperature bands are defined: less than 108°F, 108–109°F, 110–111°F, 112–113°F, 114–115°F, and greater than 115°F. For each band, a corresponding market resolves to 'Yes' if the recorded high temperature matches that range. All markets share a common secondary rule emphasizing that while other weather sources may offer guidance, The Weather Company’s official reporting is the sole authority for resolution. This structure ensures clarity and consistency in evaluating outcomes across all temperature categories.
