This set of markets assesses the likelihood of rainfall occurring in various major U.S. cities on a specific date in 2026. Each market focuses on a different location, allowing participants to evaluate regional weather conditions and make informed predictions about precipitation for that day.
Each market evaluates whether measurable rainfall will occur in a specified U.S. city on July 31, 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 and missing data are counted as zero inches and do not satisfy the 'Yes' condition. All markets use data from the Weather Company via the provided URL as the official and final source for determining precipitation levels. Participants should note that while other weather services may offer similar data, only the specified source will be used for resolution purposes. The consistent structure across all markets ensures uniform evaluation criteria, focusing solely on measurable rainfall thresholds for each location.
