This event tracks the highest temperature recorded at Miami International Airport on June 22, 2026. The outcome will be determined by the official National Weather Service Climatological Report (Daily) for that date, which provides the authoritative temperature measurement for the Miami area.
Resolution is based on the highest temperature recorded at Miami International Airport on June 22, 2026, as reported in the National Weather Service's Climatological Report (Daily). The temperature reading is divided into six distinct ranges: 88°F or below, 89–90°F, 91–92°F, 93–94°F, 95–96°F, and 97°F or above. Each range corresponds to a separate market outcome that resolves to Yes if the recorded temperature falls within that range. The NWS Climatological Report (Daily) is the sole authoritative source for resolution; preliminary NWS data and third-party weather services such as AccuWeather or Google Weather may be consulted for guidance but are not binding. Traders should be aware that preliminary NWS reporting and measurement methods may involve rounding and conversion nuances that could affect final values.
Prediction market odds reflect real-money trader conviction and aggregate dispersed information differently than traditional weather forecasts. While meteorologists issue point estimates or confidence intervals based on atmospheric models, this market prices uncertainty through continuous trading. Traders incorporate model outputs, historical patterns, and emerging data to set odds. The market-derived probabilities often reveal where professional forecasters and informed traders diverge on confidence levels, offering a complementary view to conventional analyst predictions for this specific date.
On Kalshi, this market is priced through a continuous order-book mechanism where traders submit bids and asks for outcome shares. On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. Each temperature range has its own contract, and the price of each reflects the probability traders assign to that outcome occurring. As new information emerges—updated forecasts, seasonal patterns, or real-time weather data—traders adjust their positions, moving prices up or down. The spread between buy and sell prices narrows as more liquidity enters the market.
This market resolves around Jun 23, 2026, after June 22, 2026 has passed and the actual highest temperature in Miami is recorded. The outcome is confirmed once the event is verifiable from credible public reporting. Traders holding shares in the correct temperature range receive their payout, while incorrect positions expire worthless. Resolution timing allows for official data collection and verification before final settlement.
Market prices will shift as updated seasonal forecasts and long-range weather models become available. Major climate patterns—such as El Niño or La Niña phases, Atlantic hurricane activity, or unusual heat waves—can influence June temperatures in South Florida. Real-time atmospheric data, including sea-surface temperatures and upper-level wind patterns, will drive trader adjustments closer to the event date. Breaking weather news or anomalous conditions in late spring could trigger sharp repricing as participants reassess tail-risk scenarios.
