This event tracks the overnight low temperature in Denver on Independence Day 2026. The minimum temperature will be measured and reported by the National Weather Service's official daily climatological records for Denver.
Resolution is determined by the minimum temperature recorded at Denver on July 4, 2026, according to the National Weather Service's Climatological Report (Daily). The official data source is accessed via the NWS Boulder office website under the Observed Weather tab, selecting Denver, CO with Daily Climate Report. Temperature ranges are: 56°F or below, 57-58°F, 59-60°F, 61-62°F, 63-64°F, and 65°F or above. Each range corresponds to a distinct 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 other weather services.
Prediction market odds reflect the collective judgment of traders betting real money on outcomes, often incorporating information faster than traditional forecasts. Meteorologists and climate analysts typically issue seasonal or monthly temperature outlooks, while this market aggregates trader expectations specifically for July 4, 2026 in Denver. The two sources can diverge when new data—such as updated climate models or historical weather patterns—becomes available. Comparing market odds to published forecasts reveals whether traders are pricing in more optimistic or pessimistic scenarios than official predictions suggest.
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 bracket has its own price, typically ranging from near zero to near 100 cents, reflecting the implied probability that the low temperature will fall within that range. Traders profit by correctly predicting which bracket will occur, with payouts determined by their entry price and the final outcome. The continuous two-sided market allows participants to enter or exit positions at any time before resolution.
This market resolves around Jul 5, 2026, once July 4, 2026 has passed and the day's low temperature in Denver can be verified. The outcome is confirmed through credible public reporting of official weather data, ensuring all traders reference the same authoritative measurement. Resolution typically occurs within hours of the market end date, allowing payouts to be distributed promptly. Traders should monitor weather stations and official records as the date approaches to understand how their positions may settle.
Major climate patterns and seasonal forecasts will influence trader expectations well before July 4, 2026. Updated long-range weather models, El Niño or La Niña conditions, and historical temperature trends for Denver in early July can all shift market odds. As the date draws closer, medium-range forecasts become more precise, typically causing sharper price movements. Unusual heat waves or cold snaps affecting the broader region may also prompt traders to reassess their positions. Real-time weather developments in late June will likely drive the most significant market activity in the final days before resolution.
