Highest temperature in Tokyo on August 12?

Platform comparison

Market context

On 12 August 2026, the highest temperature recorded at Tokyo Haneda Airport Station will be measured and reported via Weather Underground's Daily Observations table. The market resolves to the temperature range containing that peak reading in degrees Celsius. Resolution relies on the granular observation data rather than summary high-low figures, a distinction that occasionally produces different outcomes from casual weather reporting.

Tokyo's August temperatures have historically clustered between 32–36 °C, with extremes occasionally reaching 37–38 °C during heat waves. The 0% crowd probability suggests traders currently expect the temperature to fall outside the uppermost range bracket offered. August 2026 falls during Japan's typical summer monsoon season, when Pacific high-pressure systems and tropical moisture interact; the Japan Meteorological Agency's seasonal outlook for summer 2026 will be published in June and may shift market expectations if it signals anomalous heat or cooler conditions. Recent years have seen increased volatility in Tokyo's peak summer temperatures—the city recorded 37.5 °C on 23 July 2022 and 36.1 °C on 16 August 2023—establishing that extreme readings within the settlement window remain plausible.

From a regulatory standpoint, this market operates under German GlüStV provisions if accessed from Germany, whilst US CFTC oversight applies to American traders through Commodity Exchange Act definitions of prediction contracts. Most European jurisdictions permit weather derivatives and prediction markets with minimal KYC requirements; the €1,500 threshold common across EU-regulated platforms typically allows anonymous participation up to that stake level, making low-friction entry accessible for retail traders testing weather forecasting models without identity verification.

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 Germany Legal has a different geo footprint.

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.

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).

What if regulation changes?

If regulation changes in your jurisdiction (e.g. prediction markets are banned), Polymarket Germany Legal would geo-block the affected region and continue processing withdrawals. Your funds remain withdrawable at any time.
