This event 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, evaluating local weather conditions to determine if precipitation meets the threshold for resolution.
Each market evaluates whether the total precipitation recorded at a specified weather station in a particular U.S. city on October 2, 2026, exceeds zero inches. The official data source for all markets is the Weather Company, with values accessible via weather.com/kalshi. "Trace" amounts of rain and any missing data are counted as zero inches, meaning they do not satisfy the resolution criteria. All markets share identical secondary rules regarding data verification and the treatment of trace or missing values, ensuring consistency across locations. The resolution hinges solely on whether measurable precipitation occurs at each individual city's designated weather station on the specified date.
