This market tracks the lowest temperature recorded in Minneapolis on June 25, 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 Minneapolis on June 25, 2026, according to the National Weather Service's Climatological Report (Daily), accessible via the Minneapolis/St Paul, MN location on the NWS website. The official temperature measurement from this source is the sole determinant, regardless of preliminary reports or alternative weather services. Traders should be aware that preliminary NWS data may be subject to rounding and conversion nuances that could affect interpretation of borderline temperatures.
Prediction market odds reflect real-money incentives for accuracy, often incorporating meteorological models and historical climate data faster than traditional analyst consensus. While weather forecasters rely on deterministic models and historical averages, traders in this market price in broader uncertainty and tail risks. Over time, prediction markets tend to aggregate dispersed information—including local knowledge and emerging pattern recognition—into a single probability estimate. Comparing this market's odds to published seasonal forecasts and climate normals can reveal where traders see upside or downside surprises relative to conventional wisdom.
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 platform converts these orders into implied probabilities, displayed as a percentage chance for each outcome bracket. As new information arrives—updated weather models, seasonal shifts, or real-time conditions—traders adjust their positions, moving the price up or down. The spread between buy and sell prices reflects market liquidity and uncertainty around the exact low temperature on that date.
This market resolves around Jun 26, 2026, after June 25, 2026 has passed and the lowest temperature for that day is verifiable from credible public sources. The outcome is determined by the actual minimum temperature recorded in Minneapolis on that date, confirmed through official weather data. Once the event occurs and the temperature is officially reported, the market settles based on which outcome bracket the verified low falls into, and traders holding the correct shares receive their payouts.
Major shifts in seasonal climate patterns, updated long-range weather forecasts, and historical temperature anomalies can all influence trader positioning in this market. El Niño or La Niña conditions, changes in Arctic oscillation, and shifts in jet stream behavior may alter expectations for June 2026 conditions in the Upper Midwest. As the event date approaches, shorter-term forecasts become more precise, typically narrowing the range of likely outcomes. Real-time weather alerts, atmospheric pressure systems, and any unusual warming or cooling trends in late spring will likely trigger significant repricing as traders update their probability estimates.
