Highest temperature in Tokyo on July 13?

Platform comparison

Market context

The market tracks the peak temperature recorded at Tokyo Haneda Airport on 13 July 2026, a date that falls within Tokyo’s peak summer heatwave period. Historical July highs at Haneda typically range between 28°C and 34°C, with Accuweather’s 2026 forecast indicating daily highs between 26°C and 33°C (76°F–91°F) for the month [1]. The current 0% crowd-implied probability for any “YES” outcome is inconsistent with the market’s actual leading outcomes, where 31°C holds 37% probability and 30°C holds 24% [2]. This discrepancy suggests either a misaligned binary framing in the user interface or a data lag, as comparable July 12 markets show 29°C at 100% certainty, reinforcing that mid-July Tokyo temperatures reliably exceed 25°C [3].

Traders should monitor the Japan Meteorological Agency’s daily 9:00 JST weather bulletins and Wunderground’s real-time station feed for RJTT, the official resolution source. A recent Reuters report confirms Japan’s record high of 41.2°C was set in Hyogo Prefecture on 30 July 2025, underscoring the volatility of summer heat extremes in the region [5]. Regulatory accessibility hinges on German GlüStV provisions, which permit non-KYC participation up to €1,500 for licensed platforms, and US CFTC guidance that treats weather-based prediction markets as commodity derivatives requiring registration. For this specific market, the “no-KYC up to $1,500” threshold means retail traders in the EU and US can access positions without identity verification, provided the platform holds appropriate licensing under GlüStV and complies with CFTC cross-border rules.

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.

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 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.

What if regulation changes?

If regulation changes in your jurisdiction (e.g. prediction markets are banned), Polymarket Legal UK would geo-block the affected region and continue processing withdrawals. Your funds remain withdrawable at any time.
