This event tracks the highest temperature recorded in Las Vegas on a specific date in the future. The outcome depends entirely on official weather data from a designated source, making it a straightforward test of actual climatic conditions on that day.
The event resolves based on the maximum temperature recorded in Las Vegas (CLILAS) on September 3, 2026, as reported by The Weather Company. Six distinct temperature ranges are defined, each corresponding to a separate market that will resolve to 'Yes' if the recorded temperature falls within that range. All markets share identical secondary rules regarding data verification and error handling. The Exchange retains discretion to delay resolution if a material error is identified in the initial data publication, allowing time for a corrected report or proceeding to the Expiration Date. If no valid data remains available by the Expiration Date, all markets 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 the data from potential revision under these rules.
