Highest temperature in Tokyo on August 14?

Platform comparison

Market context

On 14 August 2026, Tokyo Haneda Airport Station will record its highest temperature for that calendar day. The market resolves to whichever temperature band captures the reading from Weather Underground's Daily Observations table—the primary source specified in the contract terms. Current crowd pricing at 0% YES reflects either extreme confidence in a specific temperature range or insufficient liquidity to establish meaningful odds across all brackets.

Tokyo's August climate is consistently hot and humid, with daily highs typically ranging from 32–35 °C. Historical data from the Japan Meteorological Agency shows that 14 August has not produced anomalous extremes; the city's record August temperature of 40.9 °C (set in 2013) remains an outlier. Comparable prediction markets on Tokyo summer temperatures have resolved within expected seasonal bands, suggesting that traders should weight recent meteorological patterns and any El Niño or La Niña conditions active in mid-2026 rather than tail-risk scenarios.

Traders monitoring this market should track Japan Meteorological Agency forecasts released in early August 2026, which typically provide 10-day outlooks with reasonable accuracy. Typhoon activity across the western Pacific in early-to-mid August could materially affect temperature and cloud cover on the settlement date. Under German GlüStV regulations, this weather derivative falls outside gaming-licence scope if structured as a pure information contract; US CFTC oversight applies only if the platform operates with US persons. The no-KYC threshold of $1,500 USD per trade means retail participants can access this market without identity verification up to that stake level, though aggregate exposure may trigger reporting obligations depending on the operator's jurisdiction.

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.
