This market tracks the lowest temperature recorded in Minneapolis on July 1, 2026. The outcome is determined by the minimum temperature reading from the National Weather Service's official daily climatological report for that date.
Resolution is based on the minimum temperature recorded at Minneapolis on July 1, 2026, as reported in the National Weather Service's Climatological Report (Daily) for the Minneapolis/St Paul, MN location. The official data source is accessed via the NWS Regional Headquarters website under the Observed Weather tab. Temperature ranges are divided into six bands: 65°F or below, 66-67°F, 68-69°F, 70-71°F, 72-73°F, and 74°F or above, with each band corresponding to a distinct market 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 data sources.
Prediction market odds often diverge from traditional meteorological forecasts because they incorporate real-time trader sentiment and broader information flows beyond historical climate models. While weather analysts rely on atmospheric data and seasonal patterns, this market aggregates the collective judgment of participants betting on the actual outcome. Over time, prediction markets have demonstrated competitive accuracy against expert forecasts, particularly when traders have financial incentive to incorporate new information. Comparing current odds to published forecasts from the National Weather Service can reveal where market participants expect conditions to differ from baseline expectations.
On Kalshi, this market is priced through a continuous order book 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 that temperature range occurring, with higher prices indicating greater confidence. As new information emerges or sentiment shifts, traders adjust their positions, causing prices to move. The platform's matching engine executes trades instantly when buy and sell orders align, ensuring transparent price discovery throughout the trading period.
This market resolves around Jul 2, 2026, once July 1, 2026 has passed and the lowest temperature for that day in Minneapolis can be verified. The outcome is confirmed against credible public sources reporting actual weather data. Traders holding shares in the correct temperature range at resolution receive their payout based on the final verified low. Until that point, prices will fluctuate as forecasts are updated and traders adjust their positions based on emerging weather models and seasonal trends.
Several factors could shift odds in this market, including updated seasonal climate forecasts, changes to long-range weather models, and historical temperature anomalies for early July in Minneapolis. Major atmospheric patterns such as heat waves, cold fronts, or unusual jet stream positioning could alter trader expectations. As summer 2026 approaches, weekly and then daily forecasts will become more precise, likely triggering sharp price movements. El Niño or La Niña conditions, solar activity trends, and any documented climate shifts could also influence how traders price temperature outcomes for that specific date.
