This set of markets assesses the likelihood of rainfall occurring in various major U.S. cities on a specific date in August 2026. Each market focuses on whether measurable precipitation will fall in a particular location, providing a localized view of potential weather conditions.
Each market evaluates whether measurable rainfall will occur in a specified U.S. city on August 16, 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 of rain and any missing data are counted as zero inches and therefore do not satisfy the condition for a 'Yes' outcome. The official data source for all markets is the Weather Company, with each market linking to a specific URL for verification. While other weather services may provide similar data, the Weather Company's reported values are the definitive measure for resolution. This consistent methodology ensures uniform evaluation across all locations, allowing participants to assess rainfall probabilities based on a single, authoritative source.
