Polymarket
This market tracks whether the highest temperature recorded at Warsaw Chopin Airport Station will reach 20°C on May 28, 2026. On Polymarket, the 20°C outcome is priced at 100.0%, while the 19°C outcome stands at 0.1%. Resolution will be determined by historical weather data from Weather Underground, which maintains official records for the Warsaw station. Watch for the actual temperature reading on May 28, 2026, when the market will settle based on the recorded high at the airport station.
Prediction market odds reflect collective trader expectations and often diverge from traditional meteorological forecasts. While weather analysts rely on numerical models and historical data, prediction markets incorporate real-time information, trader conviction, and financial incentives. Comparing Polymarket odds to official forecasts from Poland's meteorological institute or European weather services can reveal whether traders are pricing in more optimistic or pessimistic temperature scenarios. This divergence often highlights uncertainty or emerging consensus about May weather patterns in Warsaw.
The market resolves on May 28, 2026, after the highest temperature in Warsaw on May 28 has been recorded. The outcome is determined by official meteorological data for that specific date. Once the actual high temperature is reported, the winning outcome is confirmed and traders' positions settle accordingly. Early resolution is possible if conditions become impossible before the event date, though this is rare for weather markets. Traders should monitor official weather station reports from Warsaw as the date approaches.
Major weather pattern shifts, seasonal forecasts, and atmospheric pressure systems over Europe can significantly move odds. Updated meteorological models released in the weeks before May 28 often trigger repricing as new data becomes available. Unusual climate events, jet stream positioning, or anomalous high or low pressure systems over Central Europe could shift trader expectations. Real-time weather alerts and official forecasts from Poland's meteorological institute in late May will likely drive final market adjustments. Trading volume typically increases as the resolution date nears and forecasts become more precise.
