This event tracks whether measurable rainfall will occur in various major U.S. cities on a specific date in 2026. Each location has its own market determining if precipitation exceeds zero inches, providing insight into regional weather conditions for that day.
Each market resolves to Yes if the total precipitation at the specified weather station location on September 8, 2026, exceeds zero inches. All markets share identical secondary rules: official precipitation data will be sourced exclusively from The Weather Company via weather.com/kalshi, with 'trace' amounts (T) and missing values counted as zero inches. This standardized approach ensures consistent evaluation across all locations, allowing participants to assess the likelihood of measurable rainfall in each city independently while relying on a single authoritative data source for resolution.
