Frequently asked questions

The dashboard tracks real-time odds and trading activity for the highest temperature prediction in Madrid on May 28 on Polymarket. It displays current market prices, historical price movements, and 24-hour trading volume of $95,503 across all outcomes.

Prediction market odds reflect real-money trader conviction and often diverge from traditional weather analyst forecasts. While meteorologists issue probabilistic temperature ranges based on atmospheric models, market participants price in broader factors including historical May patterns, climate anomalies, and collective sentiment. The market's distributed pricing mechanism can sometimes detect shifts earlier than consensus forecasts, though both sources remain valuable for forming a complete outlook on Madrid's May 28 high temperature.

The market resolves on May 28, 2026, after the highest temperature in Madrid on May 28 has been recorded. Resolution hinges on the official temperature reading from the designated meteorological source for Madrid on that date. Whichever outcome bracket or threshold the actual high temperature falls into will determine which contracts settle to 1 and which to 0. Traders should monitor the event specifications for the exact data source and measurement methodology used.

Major weather pattern shifts, including high-pressure systems or heat waves moving into the Iberian Peninsula, could significantly move odds. Seasonal climate updates and extended forecasts from meteorological agencies often trigger repricing. Unusual atmospheric conditions—such as Saharan dust intrusions or jet stream anomalies—may alter trader expectations. As May 28 approaches, daily weather model updates and real-time atmospheric data will increasingly influence market prices, with the final week typically seeing the most volatile trading as certainty increases.
