This set of markets assesses the likelihood of specific temperature ranges in Phoenix on a particular future date. Participants can evaluate how probable it is that the day's peak temperature will fall within certain degree brackets, based on historical climate patterns and long-term weather forecasts.
All markets resolve based on the maximum temperature recorded at Phoenix (CLIPHX) on October 19, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: below 84°F, 84-85°F, 86-87°F, 88-89°F, 90-91°F, or above 91°F. The Weather Company’s data is the sole authority for resolution. Preliminary readings may differ from final values due to rounding or conversion issues, so caution is advised. If the Exchange identifies a material error in the initial data before expiration, it may delay resolution until a corrected value is published or until the expiration date. If data remains unavailable at expiration, markets resolve at the last fair price determined by Kalshi. The "Final" status on weather.com/kalshi is informational only and does not guarantee error-free data.
