This set of markets evaluates whether measurable rainfall will occur in various U.S. cities on a specific date, using standardized meteorological data sources for verification.
Each market assesses the likelihood of measurable precipitation occurring in a specific U.S. city on October 18, 2026. For a market to resolve as 'Yes,' the total precipitation recorded at the designated weather station for that city must exceed zero inches. The Weather Company serves as the authoritative source for all precipitation data, with trace amounts and missing values treated as zero inches. Participants should note that while third-party weather services may offer forecasts, only data from the Weather Company will determine the final resolution of each market. All markets share identical secondary rules regarding data verification and interpretation, ensuring consistent evaluation across locations.
