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, with outcomes determined by measured precipitation levels.
All markets share a consistent structure for determining outcomes based on precipitation data. For each specified city and corresponding weather station identifier, the market resolves to "Yes" if the recorded total precipitation strictly exceeds zero inches on October 25, 2026. Trace amounts or missing data are treated as zero inches and do not trigger a "Yes" outcome. The Weather Company serves as the exclusive source for official precipitation measurements, with data accessible via weather.com/kalshi. This standardized approach ensures uniform evaluation across all markets, despite geographic variations in climate patterns and typical rainfall probabilities for the specified date.
