Kalshi
This set of markets assesses whether measurable rainfall will occur in various major U.S. cities on a specific date in 2026. Each market focuses on a different location, providing insights into regional weather conditions 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 September 12, 2026. Precipitation totals are sourced exclusively from The Weather Company's official data portal at weather.com/kalshi. Any recorded 'trace' amounts or missing data points are treated as zero inches and do not satisfy the 'Yes' condition. All markets share identical measurement criteria and data verification protocols, ensuring consistent evaluation across locations. The outcome for each market depends solely on the numerical precipitation reading for its respective station on the designated date.
