These markets assess whether measurable rainfall will occur in various U.S. cities on a specific date in 2026. Each market focuses on a different location, using standardized weather data sources to determine outcomes based on precipitation levels.
Each market evaluates whether measurable precipitation exceeds zero inches on August 4, 2026, at a specified city's official weather station. The outcome is determined solely by the total precipitation recorded at the designated station, with any trace amounts or missing data counted as zero inches. All markets use data from the Weather Company via the provided URL (https://weather.com/kalshi) as the official and final source for verification. No other weather sources, predictions, or interpretations are considered valid for resolution purposes. The markets operate independently, meaning the result for one city does not affect others.
