Kalshi

Resolution is determined by the maximum temperature recorded at Washington DC on July 20, 2026, according to the National Weather Service's Climatological Report (Daily), accessed via the CLIDCA database at the specified NWS URL for Washington-National. The official data source is the NWS Daily Climate Report, which serves as the authoritative reference regardless of preliminary reports or alternative weather services. Temperature ranges are divided into six bands: 83°F or below, 84-85°F, 86-87°F, 88-89°F, 90-91°F, and 92°F or above. Each range corresponds to a distinct market outcome. Traders should note that preliminary NWS data may be subject to rounding and conversion nuances, and the final official report should be consulted for resolution purposes.
