Description

This event tracks the highest temperature reached in Phoenix on a specific date in the future, using official government data as the definitive source. It helps participants assess climate conditions and temperature trends for a particular location and day.

Kalshi

All markets resolve based solely on the maximum temperature recorded in Phoenix, AZ on August 9, 2026, as reported by the National Weather Service's Climatological Report (Daily). Each market corresponds to a specific temperature range: below 108°F, 108–109°F, 110–111°F, 112–113°F, 114–115°F, or above 115°F. The official NWS report is the sole authority, and traders must use the latest version available after the date in question. Preliminary data from other services may differ due to rounding or conversion differences, so only the final NWS report determines outcomes. All markets are mutually exclusive, with exactly one resolving to "Yes" based on where the actual temperature falls within these defined ranges.
