Highest temperature in Paris on June 2?

Platform comparison

Market context

On 2 June 2026, the highest temperature recorded at Paris-Le Bourget Airport Station will fall into one of several defined ranges in Celsius. The settlement relies on historical weather data from Weather Underground, which archives daily temperature records for this specific meteorological station in the Île-de-France region. The 0% crowd probability suggests traders currently perceive no meaningful likelihood of the outcome resolving to the market's specified range, though this reflects either extreme confidence in alternative ranges or insufficient liquidity rather than meteorological certainty.

June temperatures at Paris-Le Bourget typically range between 18–25°C, with historical highs occasionally reaching 28–30°C during warm spells. Comparable June days show variability driven by Atlantic weather systems and continental air masses; the station's 30-year average high for early June sits around 21°C. The current zero probability may indicate the market's range sits above typical June expectations or that traders have concentrated positions in competing temperature brackets. Historical data from Météo-France and Weather Underground archives provide benchmarks for assessing whether the specified range aligns with seasonal norms or represents an outlier scenario.

Traders should monitor European weather forecasts from mid-May onwards, particularly jet stream positioning and any developing heat systems. The UK Met Office and Météo-France issue extended outlooks 10–14 days before the settlement date. Regulatory accessibility varies by jurisdiction: German GlüStV frameworks treat prediction markets under gaming supervision, whilst US CFTC oversight applies to derivatives on real-world events. Markets with no-KYC thresholds up to $1,500 typically allow retail participation without identity verification below that stake level, though this market's specific terms determine actual accessibility.

FAQ

Do I need to KYC for PolyGram?

Not for lifetime trading volume under $1,500. Above that threshold, a quick KYC flow kicks in — ID, selfie, approximately 5-10 minutes. The threshold matches FATF travel standards for unregulated crypto platforms.

How are winnings taxed?

Tax treatment varies by jurisdiction. In most countries, prediction market gains are treated as ordinary income or capital gains. We cannot provide tax advice — consult a tax professional for your specific situation.

Can I trade anonymously?

Pseudonymously, yes — up to the KYC threshold. PolyGram stores an email address and wallet addresses rather than a legal name. Over $1,500 lifetime volume triggers KYC, after which identity is no longer anonymous.

What happens during a tax audit?

You're responsible for documenting your trades. PolyGram exports a full transaction history (CSV/PDF) for tax reporting. In an audit you'll need to present these documents.

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).
