Highest temperature in Tokyo on July 16?

Platform comparison

Market context

Tokyo’s highest temperature on 16 July 2026 will be recorded at the Tokyo Haneda Airport Station, with the market resolving to the Celsius range containing that peak. The settlement window closes at 12:00 UTC on that date, using Wunderground’s daily history for RJTT as the definitive source. Despite the crowd-implied probability of 0% for a “YES” outcome on any specific range, the frontrunner is 33°C at 41%, followed by 34°C at 30%, reflecting typical mid-July heat in the capital where daytime highs generally span 32°C to 34°C[1][2].

Historical patterns show Tokyo regularly hits 33°C–34°C in mid-July, making the 0% crowd probability for a single range an outlier likely driven by分散ed betting across multiple outcomes rather than a belief that extreme heat is impossible. Comparable cases from recent summers confirm that temperatures exceeding 30°C are standard, with 30°C or below being uncommon for daytime peaks in urban areas like Tokyo[2]. This suggests the market’s current pricing may understate the likelihood of the 33°C or 34°C ranges.

Traders should monitor daily Wunderground updates for RJTT as the date approaches, alongside Japan Meteorological Agency forecasts for heat advisories. A recent travel guide notes July daytime highs in Tokyo typically reach 32°C–34°C, reinforcing the plausibility of the frontrunner outcomes[2]. Regulatory access hinges on jurisdiction: German GlüStV implications may restrict participation for residents, while US CFTC reach could affect US traders. The “no-KYC up to $1,500” feature enhances accessibility for this weather market, allowing smaller bets without identity verification, though users must still comply with local tax and KYC thresholds where applicable.

FAQ

Do I need to KYC for Polymarket Tax 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.

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 Tax 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).
