This event tracks the highest temperature reached in Phoenix on a specific date in the future, using official government data as the sole source for verification. Participants assess whether temperatures will fall within certain ranges based on recorded measurements from trusted meteorological reports.
All markets resolve based solely on the maximum temperature recorded in Phoenix, AZ on July 29, 2026, as reported in the National Weather Service's official Climatological Report (Daily). The outcome depends on which numerical range the actual temperature falls into: below 108°F, between 108-109°F, 110-111°F, 112-113°F, 114-115°F, or above 115°F. Traders must reference the specific NWS data portal for Phoenix to verify the final figure, as preliminary or third-party sources are not considered authoritative. The rules emphasize caution regarding potential rounding differences and data update frequencies in official reports, ensuring all participants rely on the same definitive source for resolution.
