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 a particular location and 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 September 1, 2026, falls within specific Fahrenheit ranges, with outcomes resolving based on data from The Weather Company. Six distinct temperature bands are defined: 97°F or below, 98–99°F, 100–101°F, 102–103°F, 104–105°F, and above 105°F. For each band, a corresponding market will resolve to 'Yes' if the recorded high temperature matches that range. All markets use The Weather Company as the exclusive source for temperature verification, with final determinations made using their official reported values. Participants should note that preliminary readings may vary due to rounding or conversion differences, and only the finalized data from The Weather Company will be used for resolution. This structure ensures consistency and objectivity in evaluating the event’s outcome across all temperature categories.
