This event tracks whether measurable rainfall will occur in various major U.S. cities on a specific date in 2026. Each market corresponds to a different city, with the outcome determined by official weather data sources. The focus is on predicting localized weather conditions for planning and analysis purposes.
Each market evaluates whether measurable precipitation occurs in a specified U.S. city on October 7, 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. All markets use data from the Weather Company, accessed via weather.com/kalshi, as the definitive source for verification. The consistent methodology across all markets ensures uniform evaluation, with each city's specific weather station identifier (e.g., CLINYC for New York City) determining the precise location for data collection. This structure allows for localized weather prediction across diverse geographic regions.
