Highest temperature in Tokyo on August 11?

Platform comparison

Market context

On 11 August 2026, Tokyo Haneda Airport Station will record its highest temperature of the day in degrees Celsius. The market resolves using Weather Underground's Daily Observations table rather than the summary Day High & Low section, a distinction that matters when automated feeds and manual records diverge. Settlement occurs at 12:00 UTC on that date, capturing the full calendar day's peak reading.

Tokyo's August temperatures typically range between 32 and 35 degrees Celsius, with extremes occasionally exceeding 37 degrees during heat waves. Historical data from the Japan Meteorological Agency shows that August 11 itself has seen highs from 29 to 36 degrees over the past two decades, making mid-range outcomes most probable. The 0% crowd probability suggests traders are either awaiting additional context or treating this as a calibration market; comparable August-day markets on Weather Underground have resolved across multiple temperature bands without clustering at extremes.

From a regulatory standpoint, this market's accessibility depends on jurisdiction and operator licensing. Under Germany's GlüStV framework, prediction markets on weather events typically fall outside gambling regulation if structured as information contracts rather than wagering products. US CFTC oversight applies only if the operator is a registered derivatives exchange or clearinghouse; most decentralised platforms escape direct reach. The "no-KYC up to $1,500" threshold common in retail prediction markets means traders can participate with minimal identity verification below that stake level, though operators must still comply with anti-money-laundering obligations at the aggregate level. Traders should verify their platform's specific licensing jurisdiction before committing capital.

FAQ

Do I need to KYC for Is Kalshi Legal in California?

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.

What happens during a tax audit?

You're responsible for documenting your trades. Is Kalshi Legal in California 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).

What if regulation changes?

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