This market tracks the overnight low temperature in Denver 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 Denver on July 8, 2026, according to the National Weather Service's Climatological Report (Daily), accessible via the Boulder 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: 58°F or below, 59-60°F, 61-62°F, 63-64°F, 65-66°F, and 67°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 reflect real-money trader conviction and aggregate dispersed information, whereas meteorological forecasts rely on physics-based models and historical climate data. This market's odds may diverge from traditional weather forecasts because traders incorporate longer-term seasonal trends, climate patterns, and non-meteorological factors that influence public perception. Over time, prediction markets often converge toward analyst consensus as the event date approaches and model confidence increases, but early divergence can highlight where traders see underappreciated risks or opportunities in the temperature outlook.
On Kalshi, this market is priced through a continuous order-book mechanism where traders submit bids and asks for shares corresponding to different temperature outcomes. On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. The price of each outcome reflects the marginal probability assigned by the last matched trade, and wider bid-ask spreads indicate greater uncertainty among participants. As new information arrives—seasonal forecasts, climate anomalies, or historical precedent—traders adjust their positions, moving prices to reflect updated beliefs about the lowest temperature Denver will experience on that date.
This market resolves around Jul 9, 2026, once the lowest temperature recorded in Denver on July 8, 2026 is verified against credible public sources. The outcome is determined by the actual meteorological reading from that day, confirmed through official weather station data and public reporting. Once the event occurs and the temperature is officially recorded, the market settles to reflect which outcome bracket or range the true low temperature fell into, and traders' positions are finalized accordingly.
Major climate pattern shifts, seasonal forecasts, and long-range weather models will influence trader positioning over the coming months. El Niño or La Niña conditions, volcanic activity, or anomalous jet-stream behavior could alter expectations for summer temperatures in the Rocky Mountain region. As July 2026 approaches, medium-range forecasts become more reliable, typically triggering sharper price moves. Additionally, historical heat waves or cold snaps in prior years, shifts in solar activity, and any documented climate trends specific to Denver could prompt traders to reassess their positions and adjust market odds.
