Highest temperature in Tokyo on July 23?

Platform comparison

Market context

Tokyo Haneda Airport’s highest temperature for 23 July 2026 will be the settlement figure, with the market resolving to the Wunderground daily high in Celsius for RJTT. In practice, that means the outcome depends on the warmest observation recorded at the airport station during the full day, not on the noon reading or the citywide forecast, so late-afternoon heat spikes matter most.

The crowd-implied **0% YES** suggests traders currently see the event as effectively unreachable from the market’s rule set, but weather markets often reprice quickly if the day develops around an unexpected warm surge, especially under humid summer conditions. Tokyo’s July climate is typically hot and muggy: average daily highs are about 30°C, with high humidity and only partial sunshine on much of the month, which makes mid- to late-day temperature peaks the key reference point rather than early-morning conditions.[1]

From an accessibility and compliance angle, the practical question is whether the venue and user are operating under regimes that restrict access rather than whether the weather itself is tradable. German **GlüStV** rules can treat online betting-style products as tightly licensed or restricted, so access may vary for German users; in the US, CFTC reach is the larger structural issue for event-contract platforms if a product is deemed a derivatives contract. A stated *no-KYC up to $1,500* generally means smaller accounts may be able to participate with lighter identity checks, but it does not remove geoblocking, sanctions screening, or jurisdictional limits on who can use the market.

FAQ

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.
