Description

This event tracks the expected nighttime cooling in Philadelphia on a specific summer day in 2026. Participants assess whether the city will experience particularly mild or unusually warm overnight conditions based on historical climate patterns and long-range forecasts. The outcome hinges on official temperature readings from a designated weather service.

Kalshi

The event determines the resolution state based on the minimum temperature recorded in Philadelphia (CLIPHL) on August 19, 2026, as reported by The Weather Company. Six distinct temperature ranges are defined, each corresponding to a specific market outcome: 62°F or below, 63-64°F, 65-66°F, 67-68°F, 69-70°F, or 71°F and above. If the recorded minimum temperature falls within any of these ranges, the associated market resolves to Yes. All markets are mutually exclusive and collectively exhaustive, ensuring exactly one will resolve to Yes based on the actual temperature data. While other weather sources may offer similar data for reference, The Weather Company’s report is the sole authority for determining the final outcome.
