This event tracks the lowest nighttime temperature in Phoenix on a specific future date, 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 August 10, 2026, as reported in the National Weather Service's Climatological Report (Daily). The National Weather Service's data source is definitive, and traders must use the latest available version from the specified URL. While preliminary readings from other weather services may offer guidance, they do not override the NWS report. Temperature measurements may involve rounding and conversion nuances in preliminary reports, so caution is advised when interpreting early data. Six distinct temperature ranges are defined, each corresponding to a separate market outcome: below 83°F, 83-84°F, 85-86°F, 87-88°F, 89-90°F, and above 90°F. The market with the matching range will resolve as 'Yes', with all others resolving as 'No'.
