This market tracks the lowest temperature recorded in Las Vegas on June 19, 2026. The outcome will be determined by the official National Weather Service Climatological Report (Daily) for that date, which measures the minimum temperature at the Las Vegas location.
Resolution is based on the minimum temperature recorded at Las Vegas on June 19, 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 under the Observed Weather tab. Temperature readings are categorized into six ranges: 73°F or below, 74-75°F, 76-77°F, 78-79°F, 80-81°F, and 82°F or above. Each range corresponds 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, superseding preliminary reports or alternative weather services.
Prediction market odds reflect real-money trader conviction and often diverge meaningfully from traditional weather analyst forecasts. While meteorologists rely on historical climate data and seasonal models, this market incorporates live trader positioning, recent weather patterns, and emerging atmospheric signals. Comparing the implied probability from market odds to published forecasts from the National Weather Service or other agencies can reveal where traders see asymmetric risk. Markets tend to update faster than consensus forecasts when new information emerges, making them a useful cross-check against conventional predictions.
On Kalshi, this market is priced through a continuous 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 contract reflects the probability traders assign to that temperature band occurring, with the price ranging from near-zero to near-100 cents per share. Liquidity and trading volume determine how tightly bid-ask spreads are quoted. As new information arrives or trader sentiment shifts, prices adjust in real time, allowing you to enter or exit positions at market rates throughout the trading window.
This market resolves around Jun 20, 2026, after the June 19, 2026 event has concluded. The outcome is determined by the verified lowest temperature recorded in Las Vegas on that date, confirmed once the event is observable from credible public reporting. Traders holding shares in the winning outcome range receive their payout once the result is finalized and the market is settled. The exact temperature reading will be cross-checked against authoritative weather records to ensure accuracy before resolution is locked in.
Several factors could shift market pricing before resolution. Major weather pattern changes—such as an unexpected cold front, heat dome, or shift in the jet stream—would prompt immediate repricing. Seasonal climate anomalies, El Niño or La Niña developments, and long-range forecast updates from meteorological agencies often trigger trader repositioning. Real-time weather alerts, atmospheric pressure systems moving into the region, and historical temperature comparisons for that date can all influence odds. As June 2026 approaches, near-term forecasts become more reliable, typically narrowing the range of plausible outcomes and concentrating liquidity around the most probable temperatures.
