Description

This event tracks the highest temperature reached in Philadelphia on a specific date in the future, using data from a designated weather authority. It helps participants assess climate conditions and temperature trends for that exact day. The outcome depends solely on the official temperature recording from the chosen source.

Kalshi

The event determines whether the maximum temperature in Philadelphia on August 20, 2026, falls within one of several defined ranges, all evaluated against data from The Weather Company. Each market corresponds to a specific temperature band: below 80°F, 80–81°F, 82–83°F, 84–85°F, 86–87°F, or above 87°F. The market resolves to Yes for the relevant outcome if the recorded high temperature matches the specified range. All outcomes share a common secondary rule emphasizing that while alternative weather sources may offer guidance, The Weather Company’s reported maximum temperature is the sole authority for resolution. This unified framework ensures consistency across all temperature-based markets by anchoring decisions to a single, trusted data provider.
