This set of markets assesses whether measurable rainfall will occur on a specific date in various major U.S. cities. Each market focuses on a different location, allowing participants to evaluate regional weather forecasts and conditions for August 18, 2026.
Each market evaluates whether measurable precipitation occurs on August 18, 2026, in a specified U.S. city. 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 condition. All outcomes are determined using data from the Weather Company, accessed via the provided URL, ensuring consistency across all markets. Participants should note that while third-party weather sources may offer forecasts, the official data from the specified source is the sole determinant of each market's resolution.
