Highest temperature in Paris on August 20?

Platform comparison

Market context

On 20 August 2026, the highest temperature recorded at Paris-Le Bourget Airport will be measured and reported in Weather Underground's Daily Observations table. This market resolves to the temperature range bracket containing that single peak reading in degrees Celsius, with the Daily Observations data taking precedence over any summary figures. The settlement window closes at 12:00 UTC on that date, meaning the full calendar day's observations must be captured before resolution.

August temperatures at Le Bourget typically range from 15 to 27 °C, though heat waves can push readings substantially higher. The 0% crowd probability suggests traders currently expect no extreme heat event on that specific date, reflecting baseline seasonal norms rather than any forecast of unusually cool conditions. Historical August data from the station shows variability driven by Atlantic weather patterns and occasional continental high-pressure systems; comparable August days in recent years have seen highs between 20 and 25 °C under typical conditions, with outlier events exceeding 30 °C occurring roughly once per decade.

From a regulatory standpoint, this market's accessibility depends on the trader's jurisdiction. Under German GlüStV rules, prediction markets require licensing; traders in Germany should verify their platform's authorisation status. US CFTC reach extends to US persons, though most prediction markets operate outside direct CFTC oversight. Many platforms offer no-KYC trading up to $1,500 notional exposure per market, meaning traders can participate in this temperature market without identity verification below that threshold—a material consideration for retail participation in weather derivatives. Traders should monitor Météo-France forecasts and European weather models in the week preceding 20 August, as seasonal patterns and any developing pressure systems will inform positioning closer to settlement.

FAQ

Do I need to KYC for Polymarket Germany Legal?

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. Polymarket Germany Legal 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.

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).
