This event tracks the lowest temperature recorded in Phoenix on a specific Halloween night, using an authoritative weather data source. Participants assess probabilities based on historical climate patterns and seasonal forecasts for that exact date.
All markets resolve based solely on the minimum temperature recorded at Phoenix (CLIPHX) on October 31, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: 57°F or below, 58-59°F, 60-61°F, 62-63°F, 64-65°F, or 66°F and above. The Weather Company’s official reporting is definitive, even if other services show different values. Preliminary data may be subject to rounding or conversion discrepancies, so users should exercise caution. 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 passes, whichever occurs first. If no valid data exists by the expiration date, all markets resolve to the last fair price determined by Kalshi. The “Final” status on weather.com/kalshi is informational only and does not shield against potential corrections.
