Polymarket
This market tracks whether the highest temperature recorded in Panama City will reach 31°C on May 28, 2026. On Polymarket, the leading outcome—that the high will be 31°C—stands at 99.8%, while the probability of 32°C or higher is 0.1%. Resolution will be determined by historical weather data from Weather Underground, using readings from Marcos A. Gelabert International Airport Station. Watch the actual temperature reading on May 28, 2026, as it will directly determine which outcome resolves true.
Prediction market odds on Polymarket reflect real-time trader conviction about Panama City's May 28 high temperature, often incorporating meteorological models and seasonal patterns faster than traditional analyst consensus. While weather forecasters typically issue point estimates or ranges based on atmospheric data, prediction markets aggregate dispersed information through price discovery. Comparing market-implied probabilities to official forecasts from meteorological agencies can reveal whether traders are pricing in tail risks or unusual weather patterns that analysts may not yet emphasize.
The market resolves on May 28, 2026, after the highest temperature in Panama City on May 28 has been recorded and verified. Resolution depends on official temperature data from recognized meteorological sources monitoring Panama City. The outcome is determined by comparing the actual recorded high temperature against the predefined thresholds embedded in each contract outcome. Once data is confirmed, the winning outcome is settled and traders receive payouts proportional to their positions.
Major weather pattern shifts, tropical storm systems, or anomalous atmospheric conditions approaching Central America could significantly move odds. Updated seasonal forecasts from meteorological agencies, historical temperature records for late May in Panama City, and real-time weather model consensus will influence trader positioning. El Niño or La Niña phase changes, ocean temperature anomalies, and atmospheric pressure systems weeks before May 28 may also trigger repricing. As the event date nears, short-term weather forecasts become increasingly precise and can drive sharp market movements.
