This market tracks the lowest overnight temperature recorded in Denver on July 5, 2026. Resolution uses the official National Weather Service Climatological Report (Daily) for Denver, which may differ from other weather sources due to measurement methodology and rounding conventions.
Resolution is determined by the minimum temperature recorded at Denver on July 5, 2026, according to the National Weather Service's Climatological Report (Daily), accessed via the Boulder NWS office. The official temperature is divided into six ranges: 54°F or below, 55-56°F, 57-58°F, 59-60°F, 61-62°F, and 63°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 the official final value from the NWS Climatological Report takes precedence over other weather sources such as AccuWeather or Google Weather.
Prediction market odds often diverge from traditional weather analyst forecasts because they incorporate real-time trader behavior, economic incentives, and crowd intelligence rather than relying solely on numerical models. While meteorologists use physics-based simulations and historical climate data, this market reflects what informed participants actually believe will occur, sometimes pricing in tail risks or consensus shifts faster than official forecasts update. Comparing the two reveals whether the crowd is more bullish or bearish on extreme temperature outcomes than the expert consensus suggests.
On Kalshi, this market is priced through an order-book mechanism where traders directly buy and sell outcome shares, with the price reflecting the probability implied by supply and demand. On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. Each outcome represents a temperature range, and the cost of a share moves as traders adjust their positions based on new information, seasonal trends, and their conviction about Denver's weather on that specific date. Prices update continuously during trading hours, ensuring the market reflects the latest collective forecast.
This market resolves around Jul 6, 2026, once July 5, 2026 has passed and the lowest temperature recorded in Denver that day is verified against credible public sources. The outcome is determined by the actual meteorological data reported for that date, with the winning outcome corresponding to the temperature range that encompasses the verified low. Traders' positions settle based on which outcome bracket the final temperature falls into.
Major climate patterns, seasonal forecasts, and long-range weather models published by meteorological agencies can shift market odds significantly. El Niño or La Niña conditions, shifts in jet stream positioning, and historical temperature anomalies for early July in Denver all influence trader expectations. Additionally, any unusual atmospheric events, volcanic activity affecting solar radiation, or revised climate outlooks in the months leading up to July 2026 may prompt repricing as participants update their probability estimates based on evolving science and data.
