Polymarket
This market tracks whether the peak daily temperature in Wuhan will reach 27°C on May 29, 2026. On Polymarket, the 27°C outcome is trading at 33.0%, while the 28°C outcome is at 24.5%. Resolution will be determined by historical temperature data from Weather Underground, specifically measurements from Wuhan Tianhe International Airport Station. Watch for weather forecasts and seasonal patterns as May 29, 2026 approaches to gauge the likelihood of these temperature thresholds being met.
The market resolves on May 29, 2026, after the highest temperature in Wuhan on May 29 has been recorded and verified. The outcome is determined by official temperature data for that specific date. Traders holding positions in the winning outcome receive their payout, while losing positions expire worthless. The resolution hinges on accurate meteorological records from Wuhan's monitoring stations, ensuring that the actual peak temperature is compared against the contract's specified threshold to settle all open positions.
Several factors could shift odds before resolution. Major weather pattern changes—such as monsoon onset timing, tropical cyclone activity, or high-pressure systems over central China—would alter temperature expectations. Updated seasonal forecasts from meteorological agencies and real-time atmospheric data releases typically move markets. Historical temperature anomalies and climate indices like the Pacific Decadal Oscillation may influence trader positioning. As May 29 approaches, daily weather models become more precise, often triggering sharp repricing. Geopolitical or economic events affecting regional air quality could also indirectly influence temperature readings and market sentiment.
