Description

This event tracks the daily peak temperature in Philadelphia on a specific date in the future, using data from a designated weather provider. Participants assess whether conditions will fall within particular temperature ranges, helping to gauge expected weather patterns for that day.

Kalshi

All markets resolve based on the maximum temperature recorded at Philadelphia (CLIPHL) on September 25, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: 67° or below, 68-69°, 70-71°, 72-73°, 74-75°, or above 75°. The official data source is The Weather Company, and while other services may provide similar readings, they are not used for resolution. Preliminary data may be subject to rounding or conversion differences, so caution is advised. If the Exchange identifies a material error in the initial publication, it may delay expiration until a corrected version is released or until the expiration date, whichever comes first. If data remains unavailable by the expiration date, markets resolve to the last fair price determined by Kalshi. The "Final" status on weather.com/kalshi is informational only and does not guarantee error-free data.
