This market tracks the lowest temperature recorded in Atlanta on June 30, 2026. The outcome will be determined by the daily minimum temperature reported by the National Weather Service for Atlanta, divided into six temperature ranges.
Resolution is based on the minimum temperature recorded at Atlanta on June 30, 2026, as reported in the National Weather Service's Climatological Report (Daily). The official data source is accessed via the NWS Atlanta office website under the Observed Weather tab. Temperature ranges are: 71°F or below, 72-73°F, 74-75°F, 76-77°F, 78-79°F, and 80°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 final official NWS Climatological Report (Daily) serves as the authoritative source, superseding other weather services.
Prediction market odds often diverge from traditional weather forecasts because they incorporate real-time trader behavior, uncertainty premiums, and longer time horizons. While meteorologists typically issue high-confidence forecasts only days in advance, this market allows participants to price in climate patterns, seasonal trends, and historical June 30 temperatures months ahead. Comparing market-implied probabilities to published analyst models can reveal where the crowd sees tail risks or consensus blind spots, though both approaches ultimately depend on the same underlying atmospheric data.
On Kalshi, this market is priced through a continuous order-book mechanism where traders submit bids and asks for shares tied to each temperature outcome. 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 marginal probability assigned by the last matched trade, and the sum of all outcome prices equals one dollar per contract. As new information emerges or trader sentiment shifts, prices adjust in real time, allowing participants to enter or exit positions at market rates throughout the trading window.
This market resolves around Jul 1, 2026, after June 30, 2026 concludes. The outcome is determined by the verified lowest temperature recorded in Atlanta on that date, confirmed once the event is observable from credible public reporting. Traders holding shares in the correct outcome range receive their payout, while incorrect positions expire worthless. The exact resolution timing depends on data availability and platform processing, but typically occurs within hours of the close of the trading day.
Major climate patterns, seasonal forecasts, and long-range weather models can shift odds significantly. El Niño or La Niña conditions, shifts in the jet stream, and historical temperature anomalies for late June in Atlanta all influence trader positioning. As the event date approaches, medium-range forecasts become more reliable, often triggering sharp repricing. Additionally, any unusual heat waves or cold snaps in the weeks leading up to June 30 may alter expectations about atmospheric conditions, prompting traders to adjust their bets and move prices toward new equilibrium levels.
