Kalshi

All markets resolve based on the minimum temperature recorded at Washington DC (CLIDCA) on October 18, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: 32°F or below, 33-34°F, 35-36°F, 37-38°F, 39-40°F, or above 40°F. The official data source is The Weather Company, and users should exercise caution with preliminary readings due to potential rounding or conversion differences. If a material error is identified in the initial publication, the Exchange may delay expiration until a corrected value is released or until the expiration date, whichever comes first. If no data remains available by the expiration date, markets will resolve to the last fair price determined by the Exchange. The 'Final' status on The Weather Company's platform is for convenience and does not guarantee data accuracy or exempt markets from potential revisions.
