Description

This set of markets focuses on predicting the highest temperature that will be recorded in Philadelphia on a specific date in the future. Participants can bet on different temperature ranges, with the outcome determined by official weather data from a designated source.

Kalshi

These markets resolve based on the maximum temperature recorded in Philadelphia on October 9, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: 69° or below, 70-71°, 72-73°, 74-75°, 76-77°, and 78° or above. The market for the actual recorded temperature range will resolve to Yes, with all others resolving to No. All markets share common secondary rules regarding data verification and error handling. Preliminary Weather Company data may be subject to rounding or conversion differences, so participants should exercise caution when interpreting early readings. If the Exchange identifies a material error in the initial non-preliminary publication, it may delay expiration until a corrected revision is published or until the expiration date, whichever comes first. If no data remains available by the end of this period, all markets will resolve to the last fair price determined by Kalshi. The status of 'Final' on weather.com/kalshi is provided for convenience but does not guarantee data accuracy or exempt markets from these error-resolution procedures.
