Description

This event tracks whether specific temperature thresholds will be reached in Las Vegas on a particular date in the future. Participants can speculate on the likelihood of the day's highest temperature falling within various degree ranges. The outcome depends entirely on official weather data from a designated source.

Kalshi

All markets resolve based on the maximum temperature recorded at Las Vegas (CLILAS) on October 20, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: 78°F or below, 79-80°F, 81-82°F, 83-84°F, 85-86°F, or 87°F and above. If the recorded temperature falls within a market's defined range, that market resolves to Yes; otherwise, it resolves to No. Preliminary data may be subject to rounding or conversion differences, and The Weather Company’s final reported value is authoritative. The Exchange retains discretion to address material errors in initial publications, potentially delaying resolution until a corrected value is published or until the expiration date. If data remains unavailable by the expiration date, all markets resolve to the last fair price determined by Kalshi. A "Final" status on weather.com/kalshi is informational only and does not guarantee data accuracy or exempt markets from these resolution procedures.
