This event tracks the lowest nighttime temperature in Phoenix on a specific date in the future, using official government data. The outcome depends entirely on how cold it gets during that night, with different temperature ranges determining the result.
All markets resolve based solely on the official minimum temperature recording for Phoenix, Arizona on July 30, 2026, as reported in the National Weather Service's Climatological Report (Daily). Each market corresponds to a specific temperature range: below 84°F, 84-85°F, 86-87°F, 88-89°F, 90-91°F, or above 91°F. The NWS report is the definitive source, and traders must use the latest version available after the date. Preliminary data from other services may differ due to rounding or conversion differences, so only the official NWS figure determines resolution. All markets are mutually exclusive and collectively exhaustive, with exactly one resolving to "Yes" based on where the actual temperature falls within these defined bands.
