Highest temperature in Guangzhou on July 25?

Platform comparison

Market context

Guangzhou will experience peak summer heat on 25 July 2026, with the settlement hinging on the maximum temperature recorded at Baiyun International Airport's official meteorological station. Historical July data for Guangzhou shows typical highs between 32–35°C, though readings above 37°C occur in roughly one-third of years during the height of summer. The 0% crowd probability suggests traders are either awaiting clarity on the specific temperature bands offered, or the market's resolution mechanics remain unfamiliar to participants. Comparable weather markets on this platform have shown that crowd confidence in temperature predictions sharpens considerably once the settlement window narrows to within 72 hours of the event date.

Guangzhou's July temperatures depend on monsoon intensity and tropical cyclone activity in the South China Sea. The China Meteorological Administration typically issues 10-day forecasts by mid-July, which become the primary catalyst for position shifts in temperature-range markets. Any tropical system tracking toward the region in late July could suppress daytime highs, whilst persistent high-pressure systems would elevate them. Traders should monitor official CMA advisories and Wunderground's historical station data for Baiyun Airport, as this specific location's readings—rather than city-centre measurements—determine settlement.

From a regulatory standpoint, this market operates under German GlüStV provisions where applicable to EU-based participants, whilst US CFTC jurisdiction applies to American traders through Commodity Exchange Act reach. The no-KYC threshold of $1,500 USD per transaction permits retail participation in this weather market without identity verification, provided individual positions remain below that limit. Traders should verify their own jurisdictional status before committing capital.

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.

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.

What happens during a tax audit?

You're responsible for documenting your trades. Polymarket Legal UK exports a full transaction history (CSV/PDF) for tax reporting. In an audit you'll need to present these documents.

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.
