This set of markets assesses whether measurable rainfall will occur on a specific date across numerous U.S. cities. Each market focuses on a different location, evaluating local weather conditions independently. The outcome depends on official precipitation data for October 3, 2026.
Each market evaluates whether measurable precipitation occurs on October 3, 2026, in a specific U.S. city. For a market to resolve as 'Yes,' the total precipitation recorded at the designated weather station for that city must exceed zero inches. 'Trace' amounts and missing data are counted as zero inches and do not satisfy the condition. All markets use data officially reported by The Weather Company, accessible via weather.com/kalshi, as the definitive source for determining outcomes. The consistency across markets ensures uniform application of measurement standards and data verification processes.
