Kalshi
This set of markets focuses on predicting Philadelphia's lowest temperature on a specific future date. Outcomes depend entirely on official weather data from a designated source, with markets covering different temperature ranges to capture various possible scenarios.
All markets resolve based on the minimum temperature recorded in Philadelphia on September 5, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: 62°F or below, 63-64°F, 65-66°F, 67-68°F, 69-70°F, or above 70°F. The Weather Company serves as the sole authority for temperature data. Preliminary readings may differ from final values due to rounding or conversion issues. If the Exchange identifies a material error in the initial data release, it may delay resolution until a corrected version publishes or until the market's expiration date. In cases where data remains unavailable by the expiration deadline, markets resolve to the last fair price established by Kalshi. The 'Final' status on weather.com/kalshi is informational only and does not shield the data from potential revisions under these rules.
