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 exceeds zero inches at a specified weather station on September 13, 2026. The official outcome for every market is determined exclusively by precipitation data reported by The Weather Company, accessible via weather.com/kalshi. Trace amounts or missing data are counted as zero inches and do not satisfy the 'greater than zero' threshold. All markets share identical measurement standards and data sources, ensuring consistent evaluation across locations.
