This event tracks whether measurable precipitation occurs on July 17, 2026 across twenty major U.S. cities. Each city has its own independent market that resolves based on official Weather Company precipitation data for that specific date.
Resolution is determined by official precipitation data from the Weather Company (accessible via weather.com/kalshi) for each designated city location on July 17, 2026. A market resolves to Yes if total precipitation at the specified weather station exceeds zero inches. Trace amounts (T) and missing daily precipitation values are both treated as zero inches and do not trigger a Yes resolution. While other weather sources like AccuWeather or Google Weather may provide reference information, only the Weather Company's reported values serve as the official and final basis for market resolution. Each city operates as an independent market with its own designated weather station identifier.
