Highest temperature in Moscow on May 28?

Prediction market odds on Polymarket aggregate thousands of independent traders' expectations, often diverging from traditional meteorological forecasts. While weather analysts rely on atmospheric models and historical data, prediction markets incorporate real-time information, trader expertise, and financial incentives. Comparing the market's leading outcome probability to seasonal climate reports and official weather service predictions reveals whether traders are pricing in warmer, cooler, or typical conditions for late May in Moscow. This comparison highlights how market-based forecasting complements conventional meteorological analysis.

The market resolves on May 28, 2026, after the highest temperature in Moscow on May 28 has been recorded and verified. Resolution depends on official meteorological data from Moscow's primary weather station or recognized climate authority. The outcome is determined by the actual peak temperature observed on that date, measured in degrees Celsius. Once the official figure is confirmed, the corresponding outcome contract is settled at 1.00 and all other outcomes at 0.00, distributing winnings to holders of the correct prediction.

Several factors could shift odds before May 28. Updated seasonal forecasts from meteorological agencies may signal warmer or cooler conditions. Large-scale weather patterns—such as high-pressure systems, cold fronts, or unusual jet-stream positioning—directly influence Moscow's temperature. Climate anomalies, volcanic activity, or solar cycles can affect regional weather. As May approaches, short-range weather models become more reliable, typically narrowing uncertainty and sharpening market prices. Significant trader activity or new information about atmospheric conditions will also move probabilities in real time.
