This market tracks the lowest overnight temperature recorded in Minneapolis on July 5, 2026. Resolution uses the official National Weather Service Climatological Report (Daily) for the Minneapolis/St Paul area, which may differ from other weather sources due to measurement methodology and rounding conventions.
Resolution is determined by the minimum temperature recorded at Minneapolis on July 5, 2026, according to the National Weather Service's Climatological Report (Daily), accessed via the Minneapolis/St Paul NWS office. The official temperature is divided into six ranges: 58°F or below, 59-60°F, 61-62°F, 63-64°F, 65-66°F, and 67°F or above. Each range corresponds to a separate market outcome. Traders should note that preliminary NWS data may be subject to rounding and conversion nuances, and the official final value from the NWS Climatological Report takes precedence over other weather sources such as AccuWeather or Google Weather.
Prediction market odds reflect real-time trader consensus and often diverge from traditional meteorological forecasts because they incorporate broader information, including historical patterns, climate models, and market participants' collective judgment. While weather analysts publish point estimates and confidence intervals for July 5, 2026, this market prices uncertainty through continuous trading. Comparing the implied probability here to official forecasts from the National Weather Service can reveal where the crowd expects conditions to differ from baseline predictions, though both sources update as the event date approaches.
On Kalshi, this market is priced through an order-book mechanism where traders buy and sell contracts representing different temperature ranges. On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. Each contract reflects the market's current belief in the probability of that outcome, with prices ranging from near-zero to near-100 cents. Traders profit by correctly predicting which temperature band will verify on July 5, 2026, and losses occur when their positions move against actual conditions. Liquidity and spreads depend on trading activity and the number of active participants.
This market resolves around Jul 6, 2026, once the lowest temperature recorded in Minneapolis on July 5, 2026, is verified against credible public sources. The outcome is determined by official weather station data, typically from the National Weather Service or equivalent meteorological authority. Traders holding contracts aligned with the verified temperature range receive their payout, while mismatched positions expire worthless. Resolution occurs shortly after the event concludes and the data becomes publicly available.
Major climate patterns, seasonal forecasts, and atmospheric pressure systems over the Upper Midwest will influence trader expectations and shift odds throughout the prediction period. Significant weather model updates, El Niño or La Niña developments, and historical temperature anomalies for early July could trigger repricing. As July 5, 2026, approaches, real-time weather forecasts and short-term meteorological alerts will become primary drivers. Unexpected polar vortex activity or heat dome formation weeks before the event could also reshape market consensus on the likely low temperature.
