This market tracks the lowest temperature recorded in Miami on June 20, 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 Miami on June 20, 2026, according to the National Weather Service's Climatological Report (Daily), accessed via the Miami, FL location on the NWS website. The official temperature data from this NWS report is the authoritative source for resolution; preliminary data and third-party weather services may differ due to rounding and measurement methodology variations. Traders should verify data using the official NWS Climatological Report rather than relying on alternative weather sources.
Prediction market odds aggregate real-time trader behavior and reflect collective expectations about Miami's temperature low on the specified date. Analyst forecasts, by contrast, typically rely on meteorological models and historical climate data published by weather services. This market often incorporates broader information—including long-range seasonal patterns and recent climate trends—that may diverge from traditional weather forecasts. Comparing the two can reveal where traders see upside or downside risk relative to expert consensus.
On Kalshi, this market is priced through a continuous order-book mechanism where traders submit bids and asks for shares tied to specific temperature outcomes. On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. Prices move in real time as new orders execute, with the spread between buy and sell prices reflecting market liquidity and uncertainty. Higher prices indicate traders view that outcome as more likely, while lower prices suggest lower perceived probability. The platform's matching engine ensures transparent, fair-value discovery throughout the trading period.
This market resolves around Jun 21, 2026, once June 20, 2026 has passed and the actual low temperature in Miami is verifiable from credible public sources. The outcome is determined by the recorded low temperature on that date, measured in degrees Fahrenheit. Traders' positions settle based on which outcome bracket or threshold the verified temperature falls into, as defined by the market's outcome categories at launch.
Several factors may shift odds in this market: updated seasonal climate forecasts, El Niño or La Niña patterns, historical temperature anomalies for Miami in June, and real-time weather model updates as 2026 approaches. Major climate events or shifts in ocean temperatures could alter long-range expectations. Additionally, as June 20 draws closer, short-range meteorological forecasts will become more precise, likely tightening the range of expected outcomes and reducing uncertainty. Traders will continuously reprice based on the best available data.
