This event tracks the lowest temperature recorded in Seattle on a specific future date, using data from a designated weather provider. The outcome depends entirely on the exact temperature reading reported for that day, with different markets covering various temperature ranges.
All markets resolve based solely on the minimum temperature recorded at Seattle (CLISEA) on September 25, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: 46°F or below, 47-48°F, 49-50°F, 51-52°F, 53-54°F, or 55°F and above. The Exchange retains discretion to delay resolution if it identifies material errors in the initial data publication, extending until either a corrected revision is published or the expiration date passes. Should no data remain available by the expiration date, all markets resolve at the last fair price determined by Kalshi. While other weather sources may offer similar data, only The Weather Company's report is authoritative for resolution purposes. Users should exercise caution with preliminary readings due to potential rounding or conversion discrepancies.
