This event tracks the highest temperature recorded in Minneapolis on June 25, 2026. The actual temperature will be measured and reported by the National Weather Service, with resolution determined by which temperature range the recorded high falls into.
Resolution is determined by the maximum temperature recorded at Minneapolis/St Paul, MN on June 25, 2026, as reported in the National Weather Service's Climatological Report (Daily). The official data source is accessed through the NWS Climate portal for Minneapolis. Temperature ranges are: 72°F or below, 73-74°F, 75-76°F, 77-78°F, 79-80°F, and 81°F or above. Each range corresponds 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) is the authoritative source for resolution, not preliminary reports or third-party weather services.
Prediction market odds reflect aggregated trader beliefs and often incorporate information faster than traditional meteorological forecasts. While weather analysts rely on numerical models and historical climate data for June temperatures in Minneapolis, this market prices in real-time market sentiment and trader conviction. Comparing the implied probability from current odds to published seasonal forecasts can reveal where the crowd expects conditions to diverge from baseline expectations, offering insight into tail-risk scenarios.
On Kalshi, this market is priced through a continuous order-book mechanism where traders buy and sell contracts representing different temperature ranges or outcomes. On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. The bid-ask spread reflects the market's liquidity and uncertainty; tighter spreads indicate high confidence and trading volume, while wider spreads suggest lower participation or genuine disagreement on the likely outcome. Prices update in real time as new orders are placed and filled.
Major weather pattern shifts, updated seasonal climate forecasts, and long-range model consensus changes can significantly move this market. El Niño or La Niña developments, Arctic oscillation patterns, and anomalies in spring and early summer temperatures will influence trader expectations. Additionally, any revision to historical temperature records or official weather station methodology could affect how traders price tail outcomes, particularly extreme heat scenarios for the Upper Midwest.
