Highest temperature in Tokyo on August 2?

Platform comparison

Market context

Tokyo’s hottest reading on 2 August is a straight weather outcome, settled on the maximum recorded at Haneda Airport Station, so the market is mainly about how high the day’s peak gets rather than where the morning starts. Seasonal context points to a hot, humid August in Tokyo, with long-run averages around 31°C for daytime highs and frequent excursions above 30°C, while the current market is pricing a lower outcome than the climatology would suggest.[3][4][16]

The 0% yes price looks hard to reconcile with recent summer heat patterns. Tokyo has already seen severe July heat in 2026, including a 36.4°C reading in central Tokyo during the recent heatwave, and the Japan Meteorological Agency’s summer outlook cited above-normal temperatures nationwide under a strengthened Pacific High.[12][13] For comparable cases, prediction markets on single-day temperature highs often move quickly when the forecast nudges towards a narrow band, because one degree can shift the settlement range; here, the key question is whether Haneda gets a clean heating day or whether cloud cover, sea-breeze effects, or scattered showers cap the high near the low-30s rather than the mid-30s.[2][5]

The main catalysts are the hourly Tokyo forecast, any updated JMA guidance, and whether the region stays under stable high pressure or gets interrupted by convective rain later in the day.[2][5][13] On accessibility and compliance, German users are relevantly exposed to GlüStV restrictions because unauthorised online gambling participation can create local legal friction even where the market itself is offshore, while the US CFTC’s reach matters if access, promotion, or intermediated trading touches US persons or US-facing conduct. “No-KYC up to $1,500” means a user can generally enter and trade without identity verification until cumulative activity crosses that threshold, which lowers onboarding friction for small positions but does not remove platform, tax, or jurisdictional checks.

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 Legal UK has a different geo footprint.

Do I need to KYC for Polymarket Legal UK?

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 Legal UK 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).
