This event tracks the highest temperature reached in Phoenix on a specific date in the future, using official government data. Participants assess climate conditions and historical trends to predict temperature ranges, with outcomes determined by verified meteorological reports.

Kalshi

All markets resolve based solely on the maximum temperature recorded in Phoenix, AZ on July 31, 2026, as reported in the National Weather Service's official Climatological Report (Daily). Each market corresponds to a specific temperature range: below 112°F, 112-113°F, 114-115°F, 116-117°F, 118-119°F, or 120°F and above. The official NWS report is the definitive source, and traders must use the latest version available after the date in question. While preliminary data from other services may offer guidance, only the NWS report determines resolution. Traders should be aware that NWS data may include rounding or conversion nuances, and reports across cities may update at different frequencies, requiring careful verification of the exact Phoenix report.
