Highest temperature in Tokyo on August 1?

Platform comparison

Market context

Tokyo’s late-summer heat is the key real-world driver here: August is typically the hottest month in the city, with average highs around 31°C and frequent afternoons well above 33°C, so a maximum in the mid-30s is the natural baseline for this market. Historical Tokyo data also show that daily highs can sit meaningfully above the monthly average, with the city’s long-run August peak reaching 37.3°C, which helps explain why very hot outcomes remain plausible even when the crowd-implied probability is currently 0% YES.[2][10][3]

That 0% reading should be treated as a pricing signal, not as a statement that the outcome is impossible. Comparable August Tokyo summers have repeatedly produced high-30s temperatures, including recent extremes across Japan, and Tokyo’s August daily average high has been around 34.6°C in historical climate datasets, underscoring that the event sits in a hot-weather regime rather than an outlier regime.[3][16] For legal and access context, Germany’s GlüStV framework can affect whether a resident may access or lawfully participate in a given market through location checks and platform controls, while US CFTC reach is relevant because prediction markets with commodity-style event contracts can fall within US derivatives regulation depending on structure and venue; this is a regulatory framing point, not legal advice.

For traders, the main catalysts are the Tokyo Haneda Airport day-of observations and any updated forecasts that shift the expected daily maximum before the settlement cut-off, because the market resolves to the highest temperature recorded for the station on the day. A “no-KYC up to $1,500” policy generally means a user can usually open and transact below that threshold without completing identity verification, but access still depends on jurisdiction, sanctions screening, and the platform’s own geoblocking; for a German user, that can mean the market is technically visible yet practically restricted if the operator applies GlüStV-linked 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.

How are winnings taxed?

Tax treatment varies by jurisdiction. In most countries, prediction market gains are treated as ordinary income or capital gains. We cannot provide tax advice — consult a tax professional for your specific situation.

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.

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.
