This set of markets focuses on predicting the highest temperature that will be recorded in Las Vegas on a specific date in the future. The outcome depends entirely on official weather data from a designated source, reflecting how weather forecasting and data verification processes work in real-world scenarios.
All markets resolve based on the maximum temperature recorded in Las Vegas (CLILAS) on September 4, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: 92°F or below, 93-94°F, 95-96°F, 97-98°F, 99-100°F, or above 100°F. The official data from The Weather Company is the sole determinant, and users should be aware that preliminary readings may differ from final reported values due to rounding or conversion issues. If the Exchange identifies a material error in the initial data publication, it may delay resolution until a corrected version is released or until the expiration date. If no data remains 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 informational only and does not guarantee data accuracy or exempt markets from potential adjustments.
