Highest temperature in Tokyo on August 8?

Platform comparison

Market context

Tokyo is already in its hottest season, and the key event for settlement is the *highest recorded air temperature* at Tokyo Haneda Airport Station on 8 August, as taken from Weather Underground’s Daily Observations table rather than the day-summary high. Forecasts for the day cluster in the low-to-mid 30s Celsius, with JNTO showing 34°C and several other services pointing to highs around 33–35°C, so the market is starting from a materially warm baseline rather than a marginal one.[1][4][10]

That matters because the current 0% YES price leaves little room for a straightforward “hot summer day” reading; in comparable Tokyo August conditions, highs above 30°C are common and 34–35°C is a normal outcome rather than an outlier. The more useful framing is the settlement range, not a single-point exact temperature: if the airport’s observed maximum lands near 34–35°C, the market should be read very differently from one where cloud cover, sea-breeze effects, or late rain cap the peak lower. Japan’s August climate also tends to be humid and unstable enough for short-lived thunderstorms, which can blunt daytime maxima even when the broader forecast looks hot.[13][19]

On market access, this is the kind of event that sits inside a regulatory patchwork: German GlüStV issues mainly affect whether participation is offered and marketed to users in Germany, while US CFTC reach is relevant because prediction contracts tied to real-world events can fall within US derivatives scrutiny depending on venue and structure. A “no-KYC up to $1,500” limit usually means smaller accounts can trade with lighter identity checks until cumulative activity crosses that threshold, which broadens access but does not remove jurisdictional restrictions or platform-specific compliance controls.

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.

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).
