This market tracks the overnight low temperature in Denver on July 3, 2026. The outcome will be determined by the official National Weather Service daily climatological report for that date, which records the minimum temperature reached during the 24-hour observation period.
Resolution is based on the minimum temperature recorded at Denver on July 3, 2026, according to the National Weather Service's Climatological Report (Daily), accessed via the Denver station. The official data source is the NWS daily climate report available at https://www.weather.gov/wrh/Climate?wfo=bou under the Observed Weather tab. Temperature ranges are divided into six bands: 54°F or below, 55-56°F, 57-58°F, 59-60°F, 61-62°F, and 63°F or above, with each band corresponding 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, whereas traditional weather analysts rely on numerical models and historical data. This market aggregates dispersed information from many participants, often capturing nuances that single-model forecasts miss. Comparing odds here to published meteorological forecasts for Denver's low on July 3, 2026 can reveal where the crowd expects surprises or systematic model bias. Markets tend to update faster than official forecasts when new data arrives, making them a useful cross-check for serious weather watchers.
On Kalshi, this market is priced through a continuous order-book mechanism where traders buy and sell shares representing different temperature outcomes. On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. Each outcome has a price between 0 and 100 cents, reflecting the implied probability that the lowest temperature will fall within that range. As traders place bids and offers, prices adjust in real time. Liquidity and trading volume determine how tightly prices cluster around fair value, and wider spreads typically appear during lower-activity periods.
This market resolves around Jul 4, 2026, once the event has occurred and the outcome is verifiable from credible public sources. The lowest temperature recorded in Denver on July 3, 2026 will determine which outcome bracket is correct. Resolution happens after official data is published and confirmed, ensuring all traders have access to the same factual basis for settlement. Early resolution is unlikely unless the event is postponed or cancelled entirely.
Major weather pattern shifts, updated seasonal forecasts, and real-time atmospheric data will drive price movement in this market. El Niño or La Niña conditions, jet stream positioning, and high-altitude pressure systems can all influence Denver's July low. As the event date approaches, short-range forecasts from the National Weather Service and other meteorological agencies will become more precise, causing traders to adjust positions. Unusual heat waves or cold snaps elsewhere in the region may also signal changing conditions that affect local expectations.
