This event tracks the highest temperature reached in Philadelphia on a specific future date, using data from a designated weather provider. The outcome depends entirely on the official temperature recording for that day, with various temperature ranges determining different results.
All markets resolve based on the maximum temperature recorded in Philadelphia on September 24, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: below 65°F, 65-66°F, 67-68°F, 69-70°F, 71-72°F, or above 72°F. The Exchange uses The Weather Company's official reporting as the sole determinant, even if other sources show different data. Preliminary readings may vary due to rounding or conversion issues, so traders should exercise caution. If The Exchange identifies a material error in the initial data release, it may delay resolution until a corrected version is published or until the market's expiration date, whichever comes first. If no valid data exists by the end of this period, all markets resolve to the last fair price established by Kalshi. The "Final" status on The Weather Company's platform is informational only and does not guarantee error-free data or exemption from potential resolution adjustments.
