Meteorologists rely on physics-based models and historical climate data, while traders in this market incorporate real-time information, market sentiment, and incentives to forecast accurately. Over time, prediction markets have proven competitive with or superior to expert consensus on temperature outcomes, particularly when multiple independent traders contribute diverse perspectives. Comparing the odds here to published forecasts from the National Weather Service or academic climate models can reveal where market participants see opportunities or risks that conventional analysis may have missed.
