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 levels for that day.
Each market evaluates whether measurable precipitation will occur in a specified U.S. city on September 9, 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 and missing data are counted as zero inches and do not satisfy the 'Yes' 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 occurrences nationwide on the specified date.
