This set of markets assesses whether measurable rainfall will occur in various U.S. cities on a specific date in 2026. Each market focuses on a different location, evaluating the likelihood of precipitation based on official weather data.
Each market evaluates whether measurable precipitation occurs in a specified U.S. city on October 4, 2026. For a market to resolve as 'Yes,' the total precipitation recorded at the official weather station for that city must exceed zero inches. 'Trace' amounts or missing data are counted as zero inches and therefore do not satisfy the condition. All markets use data provided by the Weather Company, accessed via weather.com/kalshi, as the definitive source for determining outcomes. The consistent application of these criteria across all markets ensures uniform evaluation of rainfall occurrence nationwide.
