This market will resolve to the temperature range that contains the highest temperature recorded at the Miami Intl Airport Station in degrees Fahrenheit on 25 Jun '26. The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day for the Miami Intl Airport Station, available here: https://www.wunderground.com/history/daily/us/fl/miami/KMIA. To toggle between Fahrenheit and Celsius, click the gear icon next to the search bar and switch the Temperature setting between °F and °C. This market can not resolve until the first data point for the following date has been published on the resolution source. The resolution source for this market measures temperatures to whole degrees Fahrenheit (eg, 21°F). Thus, this is the level of precision that will be used when resolving the market. Revisions to temperatures recorded within this market's timeframe will be considered until the first datapoint for the following date has been published, after which any alterations will not be considered.

Prediction market odds reflect real-money consensus from thousands of traders and often diverge from traditional weather analyst forecasts. While meteorologists rely on numerical models and historical patterns, this market aggregates dispersed information and financial incentives, sometimes pricing in tail risks or local factors analysts may underweight. Comparing the implied probability here to official National Weather Service or private forecaster predictions can reveal where the crowd sees asymmetric value. Both approaches have merit; markets excel at synthesizing diverse data, while institutional forecasters bring specialized modeling expertise.
This market resolves around Jun 25, 2026, once the highest temperature recorded in Miami for that day is verified against credible public sources. The outcome is determined by comparing the actual peak temperature to the threshold of 81°F; if the high is 81°F or below, that outcome wins, otherwise the above-81°F outcome prevails. Traders should monitor official weather station data and National Weather Service reports as the date approaches to anticipate the likely resolution.
Major weather pattern shifts, tropical system developments, or updated seasonal forecasts could significantly move odds in either direction. If meteorologists issue warnings for an approaching cold front or high-pressure system, traders may shift toward cooler outcomes. Conversely, persistent heat domes or El Niño strengthening could push the market toward hotter temperatures. Real-time model updates from the European or American weather centers, historical analogues from prior June 25 records, and broader climate anomalies all serve as catalysts for repricing before the event settles.
