The daytime high temperature in Las Vegas on June 3, 2026, will be recorded by the National Weather Service.
The market resolves on Jun 4, 2026, after the highest temperature for June 3, 2026 has been recorded in Las Vegas. The outcome is determined by the official maximum temperature reading for that date. Once the actual high is confirmed, Kalshi will settle all shares in the corresponding outcome to their full value, and all other outcomes to zero. Traders holding shares in the correct temperature range receive their payout, while incorrect positions expire worthless. The resolution is objective and based on recorded meteorological data, ensuring a definitive settlement.
Several factors could shift market odds before resolution. Updated seasonal climate forecasts from NOAA or other meteorological agencies may signal stronger or weaker heat patterns for early June 2026. Changes in ocean temperatures, atmospheric pressure systems, or long-range teleconnection patterns could alter trader expectations. Real-time weather developments closer to June 2026 will have outsized impact as uncertainty narrows. Historical heat records and anomalies in late May 2026 may also influence how traders price the June 3 outcome. As new data arrives, market prices will adjust to reflect revised probabilities, creating trading opportunities for those monitoring weather developments and seasonal trends.
