This event tracks the lowest temperature recorded in Las Vegas on June 16, 2026. The outcome will be determined by the official National Weather Service Climatological Report (Daily) for that date, accessed through their Las Vegas station data.
Resolution is based on the minimum temperature recorded at Las Vegas on June 16, 2026, as reported in the National Weather Service's Climatological Report (Daily). The official data source is accessed via the NWS Las Vegas office website by navigating to the Observed Weather tab and selecting the Las Vegas, NV location with Daily Climate Report. The minimum temperature is divided into six ranges: 74°F or below, 75-76°F, 77-78°F, 79-80°F, 81-82°F, and 83°F or above. Each range corresponds to a distinct outcome. Traders should note that preliminary NWS reporting may be subject to rounding and conversion nuances, and the official final value from the NWS Climatological Report (Daily) takes precedence over other weather data sources such as AccuWeather or Google Weather.
Prediction market odds reflect real-money trader conviction and often diverge from traditional weather forecasts issued by meteorologists and climate analysts. While professional forecasters rely on historical data and atmospheric models, this market prices in trader expectations, which can incorporate longer-term seasonal patterns, climate anomalies, or emerging data that formal models may lag in reflecting. Comparing the implied probability here to published analyst predictions for June temperatures in Las Vegas can reveal whether traders expect conditions warmer or cooler than the consensus forecast.
On Kalshi, this market is priced through an order-book mechanism where traders buy and sell shares corresponding to different temperature ranges. On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. Each outcome range has its own bid-ask spread, and the midpoint of the tightest spread typically reflects the market's central estimate. Traders profit by correctly predicting which temperature band will verify as the actual low on the specified date. Liquidity and trading volume determine how efficiently prices adjust to new information.
This market resolves around Jun 17, 2026, once the lowest temperature recorded in Las Vegas on June 16, 2026 is verified and confirmed. The outcome is determined by comparing the final low temperature against the predefined outcome ranges offered in the market. Resolution occurs after the event date has passed and credible public reporting confirms the actual temperature reading. Traders' positions settle based on which range the verified low falls into.
Several factors could shift odds significantly before resolution. Updated seasonal forecasts, El Niño or La Niña patterns, and long-range climate models released closer to June 2026 may alter trader expectations. Unusual heat waves or cold snaps in the southwestern U.S. during spring could signal broader atmospheric trends. Historical anomalies or shifts in typical June weather patterns for Las Vegas would also influence positioning. Real-time weather updates in the weeks leading up to mid-June will likely drive the most volatile repricing as traders adjust to near-term atmospheric conditions.
