Description

This set of markets focuses on predicting Philadelphia's weather for a specific date in the future. Each market corresponds to a different temperature range, allowing participants to bet on where the actual high temperature will fall. The outcome depends entirely on official weather data from a designated source.

Kalshi

All markets resolve based on the maximum temperature recorded in Philadelphia on October 20, 2026, as reported by The Weather Company. Each market covers a specific temperature range: 65° or below, 66-67°, 68-69°, 70-71°, 72-73°, or above 73°. The official data from The Weather Company is the sole determinant, even if other sources show different values. Preliminary data may be subject to revision, and the exchange reserves the right to delay resolution if a material error is identified in the initial publication. If no valid data exists by the expiration date, markets resolve to the last fair price determined by the exchange. The "Final" status on The Weather Company’s platform is informational only and does not guarantee data accuracy or exempt markets from potential revisions.
