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 expectations for that day.
Each market resolves to Yes if the total precipitation recorded at the specified weather station for the given city exceeds zero inches on September 16, 2026. Trace amounts or missing data are counted as zero inches and therefore do not trigger a Yes outcome. All measurements are sourced from The Weather Company, with data accessible via weather.com/kalshi, ensuring consistency across all markets. The rules emphasize that while various weather services may provide similar forecasts, the official resolution relies solely on the Weather Company's reported values for each location.
