Description

This set of markets focuses on predicting Philadelphia's peak daily temperature for a specific date in the future. Outcomes depend entirely on official weather recordings, making it a straightforward test of climatic conditions on that day.

Kalshi

All markets resolve based on the maximum temperature recorded in Philadelphia on October 4, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: below 64°F, 64–65°F, 66–67°F, 68–69°F, 70–71°F, or above 71°F. The Weather Company’s data is the sole authority, though preliminary readings may vary due to rounding or conversion issues. If a material error is identified in the initial data before expiration, the market may delay resolution until corrected data is published or until the expiration date. If no data remains available by expiration, markets resolve to the last fair price determined by the exchange. The 'Final' status on The Weather Company’s platform is informational and does not guarantee error-free data.
