This market tracks the overnight low temperature in Minneapolis on July 6, 2026. The outcome will be determined by the official National Weather Service daily climatological report for the Minneapolis/St Paul area, which records the minimum temperature reached during that calendar day.
Resolution is based on the minimum temperature recorded at Minneapolis on July 6, 2026, as reported in the National Weather Service's Climatological Report (Daily) accessible via the Minneapolis/St Paul NWS office. The official data source is the NWS Daily Climate Report for Minneapolis/St Paul, MN, available through the specified NWS regional office portal. 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 for resolution. While secondary sources like AccuWeather or Google Weather may provide guidance, only the NWS Climatological Report (Daily) value is used for final determination.
Prediction market odds often diverge from traditional meteorological forecasts because they incorporate real-time trader behavior, uncertainty premiums, and collective intelligence beyond single-model outputs. While meteorologists publish deterministic or probabilistic forecasts based on atmospheric models, this market reflects what diverse participants actually believe will occur, weighted by their financial commitment. Analyst predictions tend to narrow as the event approaches and model confidence increases, whereas market odds may remain wider if traders perceive genuine uncertainty. Comparing the two reveals how much additional risk or skepticism the crowd is pricing in relative to official forecasts.
On Kalshi, this market is priced through an order-book mechanism where traders buy and sell shares corresponding to different temperature outcomes. On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. Each outcome contract trades independently, and the price of a share reflects the implied probability that the lowest temperature will fall within that range. Traders place limit or market orders, and the spread between bid and ask prices tightens as more liquidity enters the market. As new weather data or seasonal updates emerge, participants adjust their positions, causing prices to shift and revealing updated collective expectations for that July morning in Minneapolis.
This market resolves around Jul 7, 2026, once the lowest temperature recorded in Minneapolis on July 6, 2026 is verified against credible public sources. The outcome is determined by official temperature data from recognized meteorological stations serving the Minneapolis area. Traders' positions settle based on which outcome band the verified low falls into, with payouts distributed accordingly. Resolution typically occurs within hours of the market close, pending confirmation of the final temperature reading.
Several factors could shift odds in this market: seasonal climate patterns and historical July temperature trends for Minneapolis, long-range weather model updates issued weeks or days before the event, atmospheric anomalies such as unusual high-pressure systems or cold fronts, and broader climate indices like the North Atlantic Oscillation. Major weather alerts or extreme forecasts from the National Weather Service would likely trigger sharp repricing. As July 6 approaches, short-range models become more reliable, typically narrowing the range of plausible outcomes and concentrating trading volume around the most probable temperature band.
