Description

Philadelphia’s climate conditions on August 21, 2026 will classify into six temperature categories, each corresponding to a separate market outcome defined by peak temperatures.

Kalshi

The resolution of each market depends on the maximum temperature recorded at Philadelphia (CLIPHL) on August 21, 2026, as reported by The Weather Company. Six temperature ranges are specified: 77° or below, 78° to 79°, 80° to 81°, 82° to 83°, 84° to 85°, and 86° or above. The secondary rule notes that while other weather platforms may offer supplementary data, The Weather Company’s figures are the exclusive basis for determining all market results.
