This set of markets assesses whether measurable rainfall will occur in various major U.S. cities on a specific date in 2026. Each market focuses on a different location, allowing participants to evaluate regional weather conditions and make informed predictions about precipitation events.
Each market resolves to Yes if the total precipitation recorded at the specified weather station for the given city exceeds zero inches on August 25, 2026. Trace amounts or missing data are counted as zero inches and will not result in a Yes outcome. The official data source for all markets is The Weather Company, with values accessible via weather.com/kalshi. All markets share identical resolution criteria and data verification standards, ensuring consistent application across all geographic locations.
