This market tracks the lowest temperature recorded in Denver on June 25, 2026. The outcome is determined by the official National Weather Service Climatological Report (Daily) for that date, with resolution based on specific temperature ranges.
Resolution is determined by the minimum temperature recorded at Denver on June 25, 2026, according to the National Weather Service's Climatological Report (Daily), accessible via the Denver, CO location on the NWS website. The official temperature measurement from this source is the sole determinant, regardless of preliminary reports or alternative weather services. Traders should be aware that preliminary NWS data may be subject to rounding and conversion nuances that could affect interpretation of borderline temperatures.
Prediction market odds reflect real-money trader conviction and often incorporate meteorological models, historical Denver climate patterns, and long-range forecasts from professional weather services. Unlike static analyst predictions, this market continuously updates as new data arrives, allowing traders to price in seasonal trends and anomalies. The crowd-sourced nature of prediction markets can sometimes reveal insights that traditional forecasts miss, since participants have direct financial incentive to be accurate about the lowest temperature outcome.
On Kalshi, this market is priced through an order-book mechanism where traders buy and sell shares corresponding to different temperature ranges or 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 collective belief of all active traders; as new information emerges, bids and asks adjust, and the market price moves accordingly. Traders profit by correctly predicting the lowest temperature, and the platform's matching engine ensures transparent, real-time price discovery throughout the trading period.
This market resolves around Jun 26, 2026, once June 25, 2026 has passed and the lowest temperature for that day in Denver can be verified. The outcome is confirmed against credible public sources that record Denver's official temperature data. Once the actual minimum temperature is established and reported, the market settles and winning positions are paid out based on which outcome bracket or prediction was correct.
Major shifts in long-range weather forecasting, seasonal climate patterns, and atmospheric conditions over the coming months could significantly move this market. El Niño or La Niña developments, changes in jet stream positioning, and updated climate models from meteorological agencies often trigger trader repositioning. Additionally, any unusual heat or cold events in the months leading up to June 2026 may prompt traders to reassess their temperature predictions, causing price swings as new information becomes available.
