This market tracks the overnight low temperature in Minneapolis on July 3, 2026. The outcome will be determined by the official National Weather Service daily climatological report for that date, which records the minimum temperature reached during the 24-hour observation period.
Resolution is based on the minimum temperature recorded at Minneapolis on July 3, 2026, according to the National Weather Service's Climatological Report (Daily), accessed via the Minneapolis/St Paul station. The official data source is the NWS daily climate report available at https://www.weather.gov/wrh/climate?wfo=mpx under the Observed Weather tab. Temperature ranges are divided into six bands: 62°F or below, 63-64°F, 65-66°F, 67-68°F, 69-70°F, and 71°F or above, with each band corresponding to a distinct 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 trader conviction and often diverge meaningfully from traditional meteorological forecasts. While weather analysts rely on physics-based models and historical data, this market incorporates trader beliefs about model accuracy, potential forecast revisions, and tail-risk scenarios. Over time, prediction markets have proven competitive with or superior to single-model forecasts for events months away, since traders have financial incentive to incorporate all available information. Comparing current odds to the latest National Weather Service outlook can reveal where the crowd sees model uncertainty or systematic bias.
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 outcome will occur. Traders profit by correctly predicting the low temperature and can enter or exit positions at any time before the market closes, allowing prices to adjust continuously as new information emerges or sentiment shifts.
This market resolves around Jul 4, 2026, once the actual low temperature for July 3, 2026 in Minneapolis is verified and confirmed. The outcome is determined by the official recorded temperature from credible public weather data sources. Traders holding shares in the correct outcome receive their payout, while incorrect positions expire worthless. The resolution window typically closes within hours of the day's close, ensuring rapid settlement and allowing winners to redeploy capital into subsequent markets.
Major weather pattern shifts, seasonal climate anomalies, and updated long-range forecasts from meteorological agencies can all drive significant price movement in this market. El Niño or La Niña conditions, Arctic oscillation changes, and historical temperature records for early July in Minneapolis serve as key reference points traders monitor. Additionally, as July 3, 2026 approaches, short-range model consensus typically tightens, often reducing uncertainty and narrowing the range of plausible outcomes. Unexpected heat waves or cold snaps in the weeks prior may also shift trader expectations about regional temperature patterns.
