This set of markets assesses the likelihood of specific temperature ranges in Philadelphia on a particular day in the future. Each market corresponds to a different temperature band, allowing participants to speculate on how warm it might get. The outcomes are determined by official weather data from a designated source.
All markets resolve based on the maximum temperature recorded in Philadelphia on October 28, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: 64°F or below, 65-66°F, 67-68°F, 69-70°F, 71-72°F, or above 72°F. The official data from The Weather Company is the sole determinant, and users should be aware that preliminary data may differ from final reported values due to rounding or conversion issues. If a material error is identified in the initial publication, the Exchange reserves the right to delay expiration until a corrected version is released or until the expiration date, whichever comes first. In the event that no data is available by the expiration date, all markets will resolve to the last fair price determined by Kalshi. The 'Final' status on weather.com/kalshi is for convenience and does not guarantee data accuracy or exempt markets from potential revisions.
