This set of markets tracks whether measurable rainfall will occur in various major U.S. cities on a specific date in 2026. Each market focuses on a different location, allowing participants to assess regional weather conditions independently.
Each market resolves to Yes if the total precipitation recorded at the specified official weather station for the given city exceeds zero inches on August 27, 2026. Trace amounts or missing data are counted as zero. The Weather Company provides the official data source, and all markets share identical secondary rules regarding data verification and trace precipitation treatment. Participants should note that while public weather services may offer estimates, only the Weather Company's reported values will determine outcomes.
