This event tracks the lowest temperature recorded in Minneapolis on June 24, 2026. The outcome will be determined by the official National Weather Service Climatological Report (Daily) for that date, with resolution based on which temperature range the recorded minimum falls into.
Resolution is determined by the minimum temperature recorded at Minneapolis/St Paul, Minnesota on June 24, 2026, according to the National Weather Service's Climatological Report (Daily), accessible via the CLIMSP database at the Minneapolis office. The official temperature measurement from this NWS source is the sole authoritative reference; preliminary data and third-party weather services may differ due to rounding and conversion methods. Temperature ranges are divided into six bands: 54°F or below, 55-56°F, 57-58°F, 59-60°F, 61-62°F, and 63°F or above, with each range corresponding to a distinct market outcome.
Prediction market odds often diverge from traditional meteorological forecasts because they incorporate real-time trader behavior, uncertainty premiums, and longer-term climate signals. While weather analysts typically issue deterministic point forecasts or narrow confidence intervals days in advance, this market reflects distributed belief across many participants with financial incentives to be accurate. Comparing the implied probabilities here to published seasonal outlooks or ensemble forecasts from the National Weather Service can reveal whether traders are pricing in more tail risk or confidence than official models suggest. Such gaps sometimes highlight overlooked climate patterns or data that hasn't yet reached mainstream forecasts.
On Kalshi, this market is priced through an order-book mechanism where traders buy and sell shares corresponding to different temperature ranges. 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 collective probability assigned by the market. As new information arrives—seasonal forecasts, climate anomalies, or real-time weather updates—traders adjust their positions, moving prices up or down. The tighter the bid-ask spread, the more confident the market consensus; wider spreads signal disagreement or uncertainty among participants about the likely low temperature.
This market resolves around Jun 25, 2026, once the lowest temperature recorded in Minneapolis on June 24, 2026 is verified against credible public sources. The outcome is determined by the actual observed low for that calendar day, confirmed through official weather station data. Traders holding shares in the outcome band that matches the verified temperature receive their payout; all other positions expire worthless. Resolution typically occurs within hours of the close of the trading day, allowing quick settlement and payout processing.
Major climate patterns—including El Niño or La Niña phases, Arctic oscillation shifts, and seasonal jet stream positioning—can significantly influence June temperatures in Minneapolis and drive trader repositioning. Longer-range forecasts from NOAA or international meteorological centers often trigger volatility as new seasonal outlooks are released. Unexpected warming or cooling trends in late spring can shift expectations for early summer lows. Additionally, any revision to historical temperature records or changes in how official measurements are taken could alter baseline assumptions. As June 24 approaches, short-term weather models become more reliable, typically narrowing the range of plausible outcomes and compressing market odds.
