This set of markets assesses the likelihood of measurable rainfall occurring on a specific date across various U.S. cities. Each market focuses on a different location, allowing participants to evaluate regional weather forecasts and conditions for July 28, 2026.
Each market evaluates whether measurable precipitation occurs on July 28, 2026, at a specified U.S. city location. For a market to resolve as 'Yes,' the total precipitation recorded at the designated weather station 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 (https://weather.com/kalshi) as the official and final source for determining precipitation values. While other weather services may offer similar data, only the Weather Company's reported figures are authoritative for resolution purposes. This consistent methodology ensures uniform evaluation across all geographic markets.
