Highest temperature in Tokyo on August 2?

Platform comparison

Market context

Tokyo’s daytime high is likely to be set by the city’s summer heat rather than any single short-lived burst, and the market resolves on the highest temperature recorded at Tokyo Haneda Airport Station on 2 August. Tokyo’s August climate is typically hot and humid, with long-run guides putting average daytime maxima around 31°C to 35°C, while AccuWeather and other seasonal references show late-July and early-August highs commonly in the low- to mid-30s Celsius.[1][3][4][16]

The current 0% crowd price is hard to reconcile with the historical pattern for early August, when Tokyo frequently reaches 30°C or more and heat spikes above 35°C are not unusual in the wider Kanto area.[3][8][12][13] That makes the market look like a sharply contrarian or data-gap pricing, rather than a view that Tokyo will stay cool; for a weather market, the key comparison is not normalised monthly averages but the single daily maximum at the specific station used for settlement.[7][2]

For accessibility, the venue matters as much as the weather: if the platform offers **no-KYC up to $1,500**, a trader can usually enter or build a modest position without immediate identity checks, but larger balances or withdrawals may still trigger verification depending on the operator’s rules. Regulatory context is relevant too, because German **GlüStV** restrictions can affect whether a resident can lawfully access or market such a product, and the US **CFTC** may assert reach where a contract is viewed as a regulated derivative or event contract. The practical catalysts are the forecast updates, any sudden change in Tokyo’s heat pattern, and the publication of the day’s official high before the settlement window closes; traders will also watch whether clouds, rain bands, or a late-morning temperature spike alter the likely range.

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. Is Kalshi Legit has a different geo footprint.

Can I trade anonymously?

What happens during a tax audit?

You're responsible for documenting your trades. Is Kalshi Legit exports a full transaction history (CSV/PDF) for tax reporting. In an audit you'll need to present these documents.

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).
