This event tracks the peak temperature in Minneapolis on June 30, 2026, using official National Weather Service daily climate data. The outcome will be determined by the maximum temperature recorded at Minneapolis/St. Paul on that date.
Resolution is based on the maximum temperature recorded at Minneapolis on June 30, 2026, according to the National Weather Service's Climatological Report (Daily) for CLIMSP. The official data source is accessed via the NWS website by navigating to the Observed Weather tab and selecting Minneapolis/St Paul, MN with Daily Climate Report. Temperature ranges are categorized as follows: 88°F or below, 89-90°F, 91-92°F, 93-94°F, 95-96°F, and 97°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) serves as the authoritative source, superseding other weather services.
Prediction market odds reflect real-money bets from traders who have studied weather models, historical data, and seasonal trends. Unlike traditional forecasts from meteorologists or climate analysts, this market aggregates dispersed knowledge through price discovery—traders profit only if their temperature prediction proves accurate. Analyst forecasts tend to be point estimates or ranges; prediction markets instead express confidence as odds. Over time, markets often incorporate new information faster than static forecasts, making them a useful cross-check against conventional weather outlooks for this specific date and location.
On Kalshi, this market is priced through a continuous order book 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 has a bid-ask spread; you pay the ask price to go long (bet on a higher temperature) or receive the bid price to go short (bet on a lower temperature). The market price reflects the marginal trader's belief about the likelihood of each outcome. As new information emerges—updated weather models, seasonal anomalies, or climate data—traders adjust their positions, and prices move to reflect the new consensus.
This market resolves around Jul 1, 2026, once June 30, 2026 has passed and the highest temperature recorded in Minneapolis that day is verified against credible public sources. The outcome is determined by the official high temperature for that date, measured in degrees Fahrenheit. Traders holding shares in the correct outcome receive their payout; all other positions expire worthless. The resolution process is automatic once the data is confirmed, ensuring a fair and transparent settlement for all participants.
Major shifts in long-range weather forecasts, updated climate models, and seasonal anomaly reports can drive significant price moves in this market. El Niño or La Niña patterns, jet stream positioning, and historical temperature records for late June in Minneapolis all influence trader expectations. As the date approaches, short-range forecasts from the National Weather Service become more reliable and typically trigger sharper repricing. Unusual heat waves or cold snaps in the broader Midwest region may also signal changing atmospheric conditions. Real-time monitoring of meteorological data and seasonal outlooks will help you stay ahead of market repricing.
