This market tracks the highest temperature recorded in Minneapolis on June 27, 2026. The outcome will be determined by the official National Weather Service Climatological Report (Daily) for that date, with resolution based on which temperature range the recorded high falls into.
Resolution is determined by the maximum temperature recorded at Minneapolis on June 27, 2026, according to the National Weather Service's Climatological Report (Daily), accessible via the NWS website for the Minneapolis office. The official data source is the daily climate report, not preliminary reports or third-party weather services. Traders should be aware that preliminary NWS data may be subject to rounding and conversion nuances, and should use the final version of the report for the specified date. Different cities update their reports at varying frequencies, so the latest available data for June 27, 2026 should be consulted.
Prediction market odds often diverge from traditional meteorological forecasts because they incorporate real-time trader sentiment and broader uncertainty. While weather analysts rely on atmospheric models and historical data to project temperatures, this market reflects what diverse participants believe will actually occur, including tail risks and consensus shifts. Markets can move faster than official updates when new information emerges, and they sometimes price in factors analysts downweight. Comparing the two reveals whether traders are more bullish or bearish than the professional consensus, offering a complementary perspective on June 27 conditions.
On Kalshi, this market is priced through an 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 range has its own price, determined by supply and demand; as more traders bet on higher or lower temperatures, the odds shift accordingly. Participants can place limit or market orders to enter or exit positions, and the platform matches buyers and sellers in real time. Prices naturally reflect the collective probability assessment of where the high temperature will fall on that date.
This market resolves around Jun 28, 2026, once the highest temperature recorded in Minneapolis on June 27, 2026 is verified and confirmed. The outcome is determined by the actual observed peak temperature for that day, confirmed against credible public reporting. Traders holding shares in the correct outcome range receive their payout, while incorrect positions expire worthless. Resolution typically occurs within hours of the close of the trading day once official data is available.
Major weather pattern shifts, seasonal forecasts, and atmospheric anomalies can significantly move this market. Long-range climate models updated throughout spring 2026 will influence trader expectations, as will any El Niño or La Niña developments affecting North American temperatures. Unexpected heat waves in the region or broader continental warming trends could push odds higher. Conversely, cooler-than-normal patterns or increased cloud cover would lower expectations. Real-time forecast updates in late June, as the date approaches, typically drive the most volatile repricing as uncertainty narrows and models converge.
