This event tracks the highest temperature recorded in Denver, Colorado on June 24, 2026. The outcome will be determined by the official National Weather Service Climatological Report (Daily) for that date, with temperature ranges spanning from 82°F or below up to 91°F or above.
Resolution is based on the highest temperature recorded in Denver, Colorado on June 24, 2026, as reported in the National Weather Service's Climatological Report (Daily). The temperature is divided into six distinct ranges: 82°F or below, 83–84°F, 85–86°F, 87–88°F, 89–90°F, and 91°F or above. Each range corresponds to a separate market outcome that resolves to Yes if the official NWS reading falls within that bracket. The NWS Climatological Report (Daily) serves as the authoritative source; preliminary NWS data and alternative weather services such as AccuWeather or Google Weather may differ due to rounding and measurement methodology variations, so traders should rely on the final NWS report for resolution.
Prediction market odds reflect real-money positions from traders who profit or lose based on accuracy, creating strong incentives for honest price discovery. Analyst forecasts, by contrast, often rely on historical climate models and seasonal patterns without direct financial stakes. This market aggregates dispersed trader knowledge into a single price, which frequently outperforms individual expert predictions over time. Comparing this market's implied probabilities to published meteorological forecasts can reveal where the crowd sees asymmetric risk or where consensus models may be underweighting specific scenarios.
On Kalshi, this market is priced through an order-book mechanism where traders buy and sell shares corresponding to different temperature outcomes. On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. Each outcome contract trades independently, and the price of each reflects the marginal trader's belief about its likelihood. As new information emerges—weather model updates, seasonal anomalies, or historical comparisons—traders adjust their positions, moving prices up or down. The bid-ask spread and order depth indicate market liquidity and confidence around specific temperature ranges.
This market resolves around Jun 25, 2026, after June 24, 2026 concludes. The outcome is determined by the highest temperature recorded in Denver on that date, verified against credible public sources. Once the event occurs and the final temperature is confirmed, the market settles based on which outcome bracket or threshold the actual reading falls into. Traders holding positions in the correct outcome receive their payouts, while incorrect positions expire worthless.
Major weather pattern shifts, updated seasonal forecasts, and historical temperature anomalies for late June in Denver can all shift trader positioning significantly. El Niño or La Niña developments, jet stream patterns, and long-range climate models released closer to the event date often trigger repricing. Real-time weather alerts, heat waves affecting the broader region, and atmospheric pressure systems in the weeks leading up to June 24 will influence market expectations. Traders also monitor decade-long temperature trends and recent years' June records to calibrate their bids around extreme outcomes.
