Description

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 a different location, allowing participants to evaluate regional weather conditions and make informed predictions about precipitation for that day.

Kalshi

Each market evaluates whether measurable rainfall will occur on August 21, 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 of rain and any missing data are counted as zero inches and therefore do not satisfy the condition for a 'Yes' outcome. All markets use data from the Weather Company, accessible via the provided URL, as the definitive source for determining resolution. Participants should note that while other weather services may offer similar data, only the Weather Company's figures are authoritative for these markets. The resolution hinges solely on the numerical precipitation measurement for the specified date and location, with no consideration for qualitative weather descriptions or estimates from alternative sources.
