Kalshi
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 22, 2026. All markets share identical resolution criteria but apply to different geographic locations. The Weather Company serves as the exclusive source for official precipitation data, with readings accessible via weather.com/kalshi. Any recorded 'trace' amounts or missing data points are explicitly treated as zero inches and do not satisfy the 'greater than 0 inches' threshold. Market outcomes hinge solely on these verified, centralized data points rather than third-party forecasts or alternate weather services.
