This market tracks the highest temperature recorded in Las Vegas on July 6, 2026. The outcome is determined by the maximum temperature reading from the National Weather Service's official daily climatological report for Las Vegas.
Resolution is based on the maximum temperature recorded at Las Vegas on July 6, 2026, as reported in the National Weather Service's Climatological Report (Daily) for Las Vegas, NV. The official data source is accessed through the NWS Regional Headquarters website under the Observed Weather tab. Temperature ranges are divided into six bands: 103°F or below, 104-105°F, 106-107°F, 108-109°F, 110-111°F, and 112°F or above, with each band corresponding to a distinct market outcome. Traders should note that preliminary NWS data may be subject to rounding and conversion nuances, and the final official NWS Climatological Report (Daily) serves as the authoritative source for resolution, superseding other weather data sources.
Prediction market odds on this market reflect real-time consensus from traders betting money on specific temperature outcomes, whereas traditional weather forecasts rely on meteorological models and historical climate data. Markets often incorporate analyst predictions but diverge when traders identify new information or assign different probabilities to edge cases. By comparing this market's implied odds to published forecasts from the National Weather Service or climate analysts, you can identify where the crowd's expectations differ from expert models, revealing potential trading opportunities or consensus blind spots.
On Kalshi, this market is priced through an order-book mechanism where traders submit bids and asks for contracts tied to specific temperature ranges or thresholds. On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. Each contract's price reflects the probability traders assign to that outcome occurring. As new information emerges—such as updated seasonal forecasts or atmospheric patterns—traders adjust their positions, moving prices up or down. The spread between buy and sell orders indicates market confidence; tighter spreads suggest strong consensus on likely temperatures, while wider spreads reflect uncertainty.
This market resolves around Jul 7, 2026, after the highest temperature in Las Vegas on July 6, 2026 has been recorded and verified. The outcome is confirmed once credible public sources—such as official weather station data or recognized meteorological records—document the final temperature reading for that day. Traders holding positions on the correct outcome receive their winnings once resolution is complete and the platform processes settlement.
Major climate patterns, seasonal forecasts, and atmospheric anomalies released in the months leading up to July 2026 could significantly shift odds in this market. El Niño or La Niña conditions, drought severity, and long-range weather models will influence trader expectations. Unexpected heat waves or cooling trends in prior months may also prompt repricing. Additionally, historical temperature records for Las Vegas in early July and any shifts in urban heat island effects could trigger volatility. Real-time forecast updates closer to the event date typically drive the sharpest price movements.
