This event tracks whether measurable rainfall will occur in various U.S. cities on a specific date. Each location has its own market, determining if precipitation exceeds trace amounts. The outcome depends on official weather data from a designated source.
Each market evaluates whether the total precipitation in a specified U.S. city on September 14, 2026, exceeds zero inches. Precipitation data must come from the Weather Company's official reports, accessible via weather.com/kalshi. Trace amounts (T) and missing data are counted as zero inches. All markets share identical measurement criteria and data sourcing requirements, ensuring consistency across locations. The resolution hinges solely on the numerical precipitation value reported for each city, with no subjective interpretation allowed.
