Description

This event tracks the expected low temperature in Philadelphia on a specific Halloween night, helping participants gauge unusual weather patterns for that date. The outcome depends entirely on official weather recordings from a designated source.

Kalshi

All markets resolve based solely on the minimum temperature recorded at Philadelphia (CLIPHL) on October 31, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: below 38°F, 38–39°F, 40–41°F, 42–43°F, 44–45°F, or above 45°F. The Weather Company’s data is the definitive source, even if other services show different values. Preliminary readings may vary due to rounding or conversion issues, so users should exercise caution. If the Exchange identifies a material error in the initially published data, it may delay resolution until a corrected version is released or until the expiration date, whichever comes first. If no valid data exists by the end of this period, all markets resolve to the last fair price determined by Kalshi. A “Final” status on weather.com/kalshi is informational only and does not guarantee data accuracy or exempt markets from potential adjustments.
