Highest temperature in Paris on June 28?

Platform comparison

Market context

The real-world event hinges on the highest temperature recorded at Paris-Le Bourget Airport on 28 June 2026, a date concluding a historic heatwave that saw Paris hit 44°C earlier in the week before cooling to milder highs near 35°C with storm risks by Sunday [1][7]. Current crowd-implied probability of 0% YES suggests traders believe the temperature will exceed the lowest bracket, likely settling in the 29–31°C range as the heatwave eases but remains significant [3]. Historical precedents frame this probability: France’s national thermal indicator recently recorded 29.8°C as its hottest day ever, while Paris reached 44°C during the peak, indicating that even a cooling trend retains extreme warmth [2][6].

Traders must monitor the confirmation of the cooling trend beginning Friday, 26 June, and the potential for thunderstorms that could suppress temperatures on Sunday, as well as any official meteorological updates from Météo-France regarding the heat dome’s dissipation [1][9]. Recent news confirms the heatwave is easing but warns of gradual relief and storm risks, making the final Sunday reading dependent on whether storms arrive before the settlement window closes [1]. Regulatory catalysts also matter: German GlüStV implications may restrict access for EU users, while US CFTC reach could affect US traders, though the “no-KYC up to $1,500” threshold ensures this market remains accessible to smaller participants without identity verification hurdles, preserving liquidity for retail traders [3].

The settlement window ends at 12:00 UTC on 28 June 2026, meaning the final temperature reading must be captured before this deadline, with Wunderground serving as the definitive source for the highest daily temperature at Paris-Le Bourget [1]. Given the 0% YES probability, the market anticipates a result above the lowest bracket, likely 29°C or higher, reflecting the lingering heat despite the easing trend [3]. Accessibility remains key: the no-KYC rule up to $1,500 allows unverified traders to participate, while regulatory frameworks like GlüStV and CFTC oversight may limit broader participation depending on jurisdiction, shaping the market’s depth and volatility [3].

Is there a withdrawal cap?

No platform-side cap. You can withdraw any amount provided KYC is complete. SEPA bank withdrawals over €15,000 trigger additional anti-money-laundering checks (statutory obligation for all platforms).
