This market tracks the overnight low temperature in Las Vegas on July 8, 2026, as recorded by the National Weather Service. The outcome will be determined by the official NWS Climatological Report (Daily) for that date, with temperature ranges divided into six distinct brackets.
Resolution is based on the minimum temperature recorded at Las Vegas on July 8, 2026, according to the National Weather Service's Climatological Report (Daily), accessible via the Las Vegas NWS office. The official data source is the NWS Daily Climate Report, not preliminary reports or third-party weather services. Temperature outcomes are 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 separate market outcome. Traders should note that preliminary NWS data may be subject to rounding and conversion nuances, and should use the final version of the Daily Climate Report for the specified date.
Prediction market odds often diverge from traditional weather forecasts because they incorporate real-time trader positioning and risk appetite alongside meteorological models. While meteorologists issue deterministic forecasts based on atmospheric data, this market reflects probabilistic judgments shaped by financial incentives. Traders may weight longer-term climate patterns, historical July temperatures in Las Vegas, and emerging weather systems differently than official forecasters. The market price thus represents a crowdsourced probability estimate that can validate, challenge, or refine conventional analyst predictions as new information emerges.
On Kalshi, this market is priced through a continuous order-book mechanism where traders submit bids and asks for shares tied to specific temperature outcomes. On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. Share prices range from near zero to near 100 cents, with each cent reflecting a one-percentage-point probability. As traders buy and sell, the market price adjusts in real time to reflect the collective assessment of the likelihood that the Las Vegas low temperature will fall within or outside defined ranges on July 8, 2026. Liquidity and trading volume directly influence price stability and bid-ask spreads.
This market resolves around Jul 9, 2026, once the lowest temperature recorded in Las Vegas on July 8, 2026 is verified and finalized. The outcome is confirmed against credible public sources documenting the actual low temperature for that date. Traders holding shares in the outcome that matches the verified temperature receive their payout, while other positions expire worthless. Resolution typically occurs within hours of the market end date once official temperature data is published and validated.
Major weather pattern shifts, seasonal climate anomalies, and updated long-range forecasts can significantly move this market. Tropical systems, heat domes, or unexpected cold fronts affecting the Southwest would trigger repricing as traders adjust expectations. Historical temperature records and El Niño or La Niña conditions may also influence positioning. As July 8, 2026 approaches, short-term meteorological models become more reliable, typically narrowing uncertainty and stabilizing prices. Breaking news about atmospheric conditions or climate events in the weeks leading up to the date will drive active trading and volatility.
