Highest temperature in Paris on July 24?

Platform comparison

Market context

On 24 July 2026, the highest temperature recorded at Paris-Le Bourget Airport Station will determine which Celsius range resolves as correct. Historical July data from this station shows typical daily highs between 24–27°C, though heat waves can push readings above 30°C. The 0% crowd probability suggests traders currently expect no extreme heat event on that specific date, reflecting baseline seasonal patterns rather than any forecast certainty two years ahead.

Paris experienced a notable heat event in July 2022 when temperatures exceeded 40°C across northern France, though Le Bourget itself recorded lower peaks than central Paris due to its location and airport microclimate. Comparable July days at the station over the past decade show high variability: some years peak near 20°C during cooler spells, whilst others reach 28–29°C during typical summer conditions. The current 0% reading likely reflects the market's difficulty in pricing tail-risk heat scenarios so far in advance rather than confidence that moderate temperatures will prevail.

Traders should monitor European weather forecasting updates from Météo-France and the European Centre for Medium-Range Weather Forecasts (ECMWF) as July 2026 approaches, particularly any signals of Atlantic blocking patterns or heat dome formation. The resolution depends entirely on Wunderground's historical data for Le Bourget; temperature station reliability and data availability should be verified before settlement. From a regulatory standpoint, this weather derivative falls under German GlüStV oversight if accessed from Germany, whilst US CFTC jurisdiction applies to US persons. Markets under $1,500 notional typically avoid KYC requirements on certain platforms, though individual operators' policies vary.

FAQ

Is Polymarket legal in my country?

Polymarket is geo-blocked in the US/UK/EU. Actual usage via the Polymarket interface is not possible there. The legal status itself varies — many countries treat prediction markets as a gray area. Polymarket Legal UK has a different geo footprint.

Can I trade anonymously?

Pseudonymously, yes — up to the KYC threshold. Polymarket Legal UK 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. Polymarket Legal UK exports a full transaction history (CSV/PDF) for tax reporting. In an audit you'll need to present these documents.

Are prediction markets gambling?

Legally unclear in most jurisdictions. Some interpretations classify them as wagering (gambling regulation applies), others as derivatives (financial regulation applies). There's no global precedent specifically for on-chain prediction markets.

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).
