This event tracks the lowest temperature recorded in Minneapolis on June 17, 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 minimum falls into.
Resolution is determined by the minimum temperature recorded at Minneapolis on June 17, 2026, according to the National Weather Service's Climatological Report (Daily), accessible via the CLIMSP database at the Minneapolis/St Paul office. The official data source is the NWS Daily Climate Report, not preliminary reports or third-party weather services. Temperature ranges are divided into six bands: 48°F or below, 49-50°F, 51-52°F, 53-54°F, 55-56°F, and 57°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 report should be used for resolution. Different cities update their climate reports at varying frequencies, so the latest available data for the specified date must be consulted.
Prediction market odds reflect real-money incentives for accuracy, often incorporating meteorological forecasts, historical climate patterns, and emerging seasonal trends. Professional weather analysts and climate models provide baseline expectations, but this market aggregates the views of many traders who profit only if their temperature prediction proves correct. Over time, prediction markets tend to absorb analyst consensus while also pricing in tail risks and uncertainty that traditional forecasts may underweight. Comparing the two reveals where traders see divergence from official predictions.
On Kalshi, this market is priced through a continuous order-book mechanism where traders submit bids and asks for shares corresponding to different temperature outcomes. On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. The price of each outcome reflects the probability traders assign to it—higher prices indicate greater confidence that outcome will occur. As new information arrives, traders adjust their positions, moving prices up or down. The spread between bid and ask prices tightens when conviction is high and widens during uncertainty, making the order book a dynamic reflection of real-time market sentiment.
This market resolves around Jun 18, 2026, after June 17, 2026 has passed and the lowest temperature recorded in Minneapolis that day becomes verifiable. The outcome is confirmed once credible public reporting—typically from the National Weather Service or equivalent meteorological authority—documents the official low temperature. Traders holding shares in the correct outcome receive their payout based on the final verified reading. Resolution timing allows for data collection and validation before the market settles.
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, Arctic air outbreaks, or unusual jet-stream positioning weeks before June 2026 would influence trader positioning. Real-time forecast updates from the National Weather Service in the days leading up to June 17 typically drive sharp price movements as traders react to refined predictions. Historical temperature records for that date and broader climate trends also serve as anchors for market repricing.
