Polymarket
This market tracks whether the highest temperature recorded in Wuhan will reach 29°C on May 28, 2026. On Polymarket, the leading outcome—a high of 29°C—stands at 99.9%, while the alternative of 31°C carries 0.1% probability. Resolution will be determined by Weather Underground's historical data from Wuhan Tianhe International Airport Station. Watch the actual temperature reading on May 28, 2026, as that date will trigger final settlement based on the recorded high.
Prediction market odds on Polymarket reflect real-money consensus from traders pricing in meteorological data, seasonal patterns, and climate models. Unlike traditional analyst forecasts, which rely on expert judgment and historical averages, markets aggregate distributed information through continuous price discovery. The current leading outcome on Polymarket suggests traders are pricing in specific temperature scenarios for Wuhan on May 28. Comparing market odds to official weather service forecasts and climate analyst reports can reveal where traders diverge from institutional predictions.
Several factors could shift odds before May 28. Major weather pattern changes, such as monsoon onset timing or tropical systems affecting East Asia, would alter temperature expectations. Updated seasonal forecasts from meteorological agencies and shifts in atmospheric pressure systems could move markets significantly. Real-time weather data closer to the date, including satellite imagery and model consensus, typically drives late-stage price movements. Traders also react to historical temperature records for late May in Wuhan and any unusual climate anomalies reported in the weeks leading up to the event.
