This event tracks the lowest temperature recorded in Philadelphia on a specific date in the future, using data from a designated weather provider. The outcome depends entirely on how cold it gets during that night, with different markets covering various temperature ranges.
All markets resolve based solely on the minimum temperature recorded at Philadelphia (CLIPHL) on September 20, 2026, as reported by The Weather Company. Each market covers a specific temperature range: 56°F or below, 57-58°F, 59-60°F, 61-62°F, 63-64°F, or 65°F and above. If the recorded low falls within a market's designated range, that market resolves to Yes; otherwise, it resolves to No. The Exchange retains discretion to delay resolution if it identifies material errors in the initial data publication, extending the evaluation period until either a corrected value is published or the expiration date passes. In cases where data remains unavailable by the expiration date, all markets will resolve to the last fair price determined by Kalshi. Preliminary readings may differ from final values due to rounding or conversion differences, and users should exercise caution when interpreting early data. The "Final" status on weather.com/kalshi is informational only and does not guarantee data accuracy or exempt markets from potential resolution adjustments.
