The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day for the Cape Town International Airport Station, available here: https://www.wunderground.com/history/daily/za/matroosfontein/FACT. To toggle between Fahrenheit and Celsius, click the gear icon next to the search bar and switch the Temperature setting between °F and °C.

Prediction market odds represent real-money bets from traders worldwide, while analyst forecasts typically come from meteorological models and expert opinion. This market aggregates dispersed information and financial incentives into a single price signal. Analysts may issue point forecasts or ranges based on atmospheric data; traders here are pricing the probability of specific temperature outcomes. When the two diverge significantly, it often signals either new information entering the market or gaps in traditional forecasting. Both sources offer value, but they operate through fundamentally different mechanisms.
This market resolves around Jul 4, 2026, once the highest temperature recorded in Cape Town on July 4 is verifiable from credible public sources. The outcome is determined by comparing actual weather data against the specific temperature thresholds defined in each contract. No further trading occurs after the resolution window opens. Traders who correctly predicted the outcome receive their winnings, while incorrect positions expire worthless.
Weather forecasts and seasonal climate patterns are primary drivers. Updated meteorological models from major weather services can shift trader expectations significantly. Unusual atmospheric conditions—such as early winter storms, heat waves, or ocean temperature anomalies—may surprise the market. Historical temperature records for Cape Town in early July provide a baseline; deviations from the norm can trigger repricing. As July 4 approaches, real-time weather updates and short-term forecasts typically increase volatility. Breaking news about regional climate events can also influence positions.
