This market tracks the lowest temperature recorded in Denver on June 27, 2026. The outcome is determined by the minimum temperature reported by the National Weather Service's daily climatological report for that specific date.
Resolution is based on the minimum temperature recorded at Denver on June 27, 2026, as reported in the National Weather Service's Climatological Report (Daily) for the Denver, CO location. The official data source is accessed via the NWS Regional Headquarters website under the Observed Weather tab. Temperature readings are categorized into six ranges: 54°F or below, 55-56°F, 57-58°F, 59-60°F, 61-62°F, and 63°F or above, with each range corresponding to a distinct market 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 for resolution, superseding other weather data sources.
Prediction market odds reflect the aggregated beliefs of traders betting real money, which often diverge from traditional weather analyst forecasts. While meteorologists rely on physics-based models and historical data, this market prices in trader conviction and real-time information flows. Comparing the implied probability from current odds to published forecasts from the National Weather Service or other meteorological institutions can reveal where the crowd sees value or risk. Prediction markets tend to update faster than formal forecasts as new data emerges, making them a useful cross-check for understanding where professional and crowd expectations align or diverge on the June 27 low temperature.
On Kalshi, this market is priced through a continuous order book where traders submit bids and asks for contracts tied to specific temperature ranges or thresholds. On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. The platform matches buyers and sellers in real time, and the midpoint of the spread reflects the market's consensus probability at any given moment. As new information emerges—updated weather models, seasonal patterns, or atmospheric data—traders adjust their positions, moving the price up or down. This dynamic pricing mechanism ensures the market continuously incorporates fresh signals about what the lowest temperature in Denver will be on the target date.
This market resolves around Jun 28, 2026, once June 27, 2026 has passed and the actual low temperature for Denver can be verified. The outcome is confirmed by comparing reported weather data against credible public sources, ensuring an objective and transparent settlement. Traders holding positions aligned with the verified temperature will receive their payouts based on the final result. Until that date, the market remains open for trading, allowing participants to adjust their exposure as forecasts and conditions evolve.
Several factors could shift odds in this market before resolution. Updated seasonal forecasts and long-range weather models from meteorological agencies often trigger repricing as traders incorporate new data. Major atmospheric patterns—such as high-pressure systems, jet stream positioning, or moisture availability—can influence the expected low. Real-time weather developments in late June, including frontal passages or heat waves, will likely drive sharp price movements as the event date nears. Additionally, historical temperature records and climate anomalies for Denver in late June may prompt traders to reassess their positions, especially if unusual conditions develop in the days immediately before the market resolves.
