Kalshi

The event resolves based on the maximum temperature recorded at Washington DC on July 29, 2026, as reported by the National Weather Service's Climatological Report (Daily). Six distinct temperature ranges are defined, each corresponding to a specific market outcome. If the temperature is 82°F or below, the first market resolves to Yes. If it falls between 83°F and 84°F, the second market resolves to Yes, and this pattern continues for temperatures between 85°F-86°F, 87°F-88°F, and 89°F-90°F. For any temperature above 90°F, the final market resolves to Yes. The official NWS data, accessible via the provided URL, is the sole source for determining the outcome. Traders must use the latest version of the data and remain cautious about preliminary reports, rounding, and conversion nuances, as these can affect interpretations before the official report is finalized.
