This market tracks the lowest temperature recorded in Denver on June 21, 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 21, 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; preliminary NWS data and third-party weather services are not authoritative. Temperature readings are subject to rounding and conversion nuances inherent in NWS measurement methods, and traders should exercise caution when interpreting preliminary data before the official daily report is finalized.
Prediction market odds often diverge from traditional meteorological forecasts because they incorporate real-time trader behavior, uncertainty premiums, and forward-looking sentiment. While weather analysts rely on deterministic models and historical climate data, this market aggregates the collective judgment of traders who profit from accurate predictions. Analyst forecasts tend to narrow as the event date approaches and models converge, whereas market odds may remain wider to reflect genuine uncertainty or trader disagreement. Comparing the two reveals whether the market is pricing in tail risks or consensus views that professional forecasters might underweight or overlook.
On Kalshi, this market is priced through a continuous 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 bid-ask spread, and the mid-price reflects the equilibrium between buyers and sellers at any given moment. Traders can enter limit or market orders to express their view on the lowest temperature, and prices adjust dynamically as new information arrives and positions shift. The platform's matching engine ensures transparent price discovery, with all trades executed at posted prices visible to the broader market.
This market resolves around Jun 22, 2026, once the lowest temperature recorded in Denver on June 21, 2026 is verifiable from credible public sources. The outcome is determined by official meteorological data, typically from the National Weather Service or equivalent authoritative weather reporting. Traders' positions settle based on which temperature bracket the actual low falls into, with payouts distributed accordingly. Resolution occurs shortly after the event date once the final reading is confirmed and published.
Major weather pattern shifts, seasonal climate anomalies, and updated long-range forecasts from meteorological agencies can significantly move this market. El Niño or La Niña conditions, jet stream positioning, and high-altitude pressure systems influence Denver's June temperatures and will drive trader repositioning. As spring progresses into early summer, medium-range forecasts become more reliable, typically tightening market odds around 10–14 days before the event. Unexpected heat waves or cold snaps in adjacent regions, changes to solar activity predictions, or shifts in atmospheric circulation patterns may also trigger rapid repricing as traders update their probability assessments.
