This event assesses whether measurable rainfall will occur in various major U.S. cities on a specific date, offering insights into localized weather conditions and helping gauge regional climate expectations for that day.
Each market evaluates whether measurable precipitation—defined as strictly greater than 0 inches—will occur at a specified weather station in a particular U.S. city on October 20, 2026. All markets follow the same core resolution rule but apply it to different geographic locations. The Weather Company serves as the exclusive source for official precipitation data, with values accessible via weather.com/kalshi. Any recorded 'trace' amounts or missing data points are explicitly treated as 0 inches and therefore do not satisfy the 'greater than 0 inches' threshold required for a 'Yes' outcome. This uniform framework ensures consistent evaluation across all participating cities, allowing participants to assess the likelihood of rain in each location independently while adhering to a standardized methodological approach for data verification and resolution.
