Pronóstico: Highest temperature in Madrid on June 29?

Platform comparison

Market context

On 29 June 2026, the Adolfo Suárez Madrid-Barajas Airport Station will record its peak temperature for the day, a metric that directly determines the outcome of this prediction market. The current crowd-implied probability of 0% for the "YES" outcome suggests traders believe the temperature will fall outside the specified range, likely due to expectations of either significantly higher heat or a cooler anomaly. This stark positioning contrasts with historical patterns where late June in Madrid typically sees highs near 31.8°C, with June 30 being the warmest average day of the month[3].

Historical data from June 2026 reveals a volatile temperature spread, with the highest maximum recorded at 38.3°C on June 22 and a low minimum of 13.8°C on June 5[4]. The average high for the month sits at 99°F (37.2°C), while daily highs have ranged between 95°F and 102°F (35°C to 39°C)[1]. Given that the record high for Madrid is 40.7°C, the current 0% probability implies the market expects the temperature to exceed the upper bound of the range rather than stay within it, aligning with the trend of late-June heatwaves that often push temperatures toward 39°C or higher[5].

Traders must monitor real-time updates from Wunderground, the official resolution source, for any sudden shifts in atmospheric conditions or cloud cover that could alter the peak temperature[1]. Specific catalysts include the scheduled release of the daily weather summary for June 29, which will confirm the exact Celsius reading at the airport station. Additionally, any unexpected weather advisories or sudden changes in wind patterns from the Atlantic could act as a cooling dependency, though the prevailing forecast suggests continued heat[2]. The final settlement will occur at 12:00 UTC on 29 June 2026, making the immediate hours before this deadline critical for verifying the Wunderground data[1].

FAQ

Are prediction markets better than sports betting?

Prediction markets tend toward tighter odds than bookmakers because they use peer-to-peer exchange rather than bookmaker margin. On major matches, Polymarket quotes typically sit 2-5% closer to the true probability model than bet365 or DraftKings.

When do sports markets resolve?

Typically within hours of the official final whistle. Polymarket uses UMA Optimistic Oracle with source URLs pointing at official league data feeds — e.g. the Premier League for EPL markets, UEFA for Champions League, FIFA for World Cup.

Can I bet on individual matches?

Yes, Polymarket lists every major Premier League / Champions League / World Cup match as its own market. Liquidity varies — top matches like El Clásico or a semi-final often have six-figure pools, lower-league games closer to three-figure.

Which sports markets are available?

Football (soccer) dominates — Champions League, World Cup, Premier League, La Liga, Bundesliga — followed by NFL, NBA, tennis Grand Slams, Formula 1, boxing/MMA. Resolution via official league source confirmation.

Can I import form data and lineups?

This page shows the live Polymarket quote as an implied probability. Form data and lineups must be researched separately via sports data providers (e.g. Soccerway, ESPN, FBref) — we surface the market probability, not the sport analysis.
