Highest temperature in Tokyo on July 5?

Platform comparison

Market context

The real-world event this market tracks is the peak heat recorded at Tokyo Haneda Airport on 5 July 2026, measured in degrees Celsius by Wunderground. Historical data for Haneda in July shows daily highs typically ranging between 28°C and 33°C (82–91°F), with an average high near 25°C overall for the month, though peak days often exceed 30°C. Comparable cases from recent summers indicate that a 0% crowd-implied probability for a specific high-temperature range is unusual unless the range is implausibly extreme, such as below 20°C or above 45°C, which contradicts established climate patterns for the region.

Traders should monitor the official Japanese Meteorological Agency’s weekly forecasts and any sudden shifts in the Pacific high-pressure system, which directly influences summer heat intensity in Tokyo. A recent report from Agate Travel confirms that July remains the tail end of the stuffy plum rainy season, with temperatures stabilising around 28–33°C during the day, suggesting that extreme deviations are unlikely without a major atmospheric anomaly. Regulatory catalysts also matter: German GlüStV implications may restrict access for EU residents, while US CFTC reach could affect traders in the Americas. The “no-KYC up to $1,500” rule means this market remains accessible to small-scale participants without identity verification, but only if they fall within jurisdictions that permit unregulated prediction trading.

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. Is Kalshi Legit 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. Is Kalshi Legit 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), Is Kalshi Legit would geo-block the affected region and continue processing withdrawals. Your funds remain withdrawable at any time.
