This market tracks the overnight low temperature in Denver on July 2, 2026. The outcome will be determined by the official National Weather Service daily climatological report for Denver, which records the minimum temperature reached during that calendar day.
Resolution is based on the minimum temperature recorded at Denver on July 2, 2026, as reported in the National Weather Service's Climatological Report (Daily) for Denver, CO. The official data source is accessed via the NWS Regional Headquarters website under the Observed Weather tab. Temperature ranges are divided into six categorical bands: 52°F or below, 53-54°F, 55-56°F, 57-58°F, 59-60°F, and 61°F or above. Each temperature 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 report should be used for resolution rather than real-time or third-party weather services.
Prediction market odds reflect real-money bets from traders who profit or lose based on accuracy, creating strong incentives for honest price discovery. Analyst forecasts, by contrast, are typically point estimates or ranges issued by meteorologists and climate services without direct financial stakes. This market aggregates dispersed information from many participants, often capturing nuances that single-source forecasts may miss. Comparing the two reveals whether professional meteorologists and market participants align on expected outcomes or diverge in their assessments of July 2026 Denver conditions.
On Kalshi, this market is priced through an 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 range occurring, with prices ranging from near-zero to near-unity. Bid-ask spreads tighten as volume increases, and the mid-market price at any moment represents the marginal trader's belief. Settlement payouts are determined by which temperature range verifies as correct once the event concludes.
This market resolves around Jul 3, 2026, after July 2, 2026 has passed and the lowest temperature recorded in Denver that day is confirmed. The outcome is determined by verified meteorological data from credible public sources, ensuring an objective and auditable result. Once the final temperature is established and cross-checked, the market settles automatically and payouts are distributed to holders of the winning outcome contract. No further trading occurs after resolution.
Major weather pattern shifts, updated seasonal climate forecasts, and long-range model consensus changes will likely drive significant price movement in this market. El Niño or La Niña developments, atmospheric pressure anomalies, and jet-stream positioning over the western United States could all influence Denver's July 2026 temperature outlook. As the event date approaches, near-term weather models become more reliable and will sharpen market pricing. Traders monitoring NOAA forecasts, Climate Prediction Center outlooks, and historical temperature trends for that date will continuously reassess their positions.
