Highest temperature in Guangzhou on July 1?

Platform comparison

Market context

The underlying real-world event is the highest temperature recorded on 1 July 2026 at Guangzhou Baiyun International Airport, measured in degrees Celsius via Wunderground. Historically, July in Guangzhou is the hottest month, with daytime highs typically ranging from 34 to 37°C and extremes exceeding 38°C[1]. Notably, the highest temperature ever recorded in Guangzhou was 39.1°C on 1 July 2004, exactly matching the date of this market’s settlement window[3]. This historical precedent suggests that a 0% YES probability for any temperature range is highly unusual, given that temperatures on this date have previously reached record levels[3].

Traders should monitor upcoming weather forecasts and climate announcements for southern China, particularly any reports on record-breaking heatwaves. Recent data indicates China experienced its hottest July on record since comprehensive data collection began in 1961, with the highest average temperature ever recorded[4]. This trend of intensifying summer heat could significantly influence the likelihood of high temperatures on 1 July 2026. Additionally, regulatory frameworks such as Germany’s GlüStV and US CFTC rules may impact market accessibility, while the “no-KYC up to $1,500” provision allows broader participation for this specific weather-based prediction market without identity verification.

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 Polymarket Legal in Canada has a different geo footprint.

Can I trade anonymously?

Pseudonymously, yes — up to the KYC threshold. Is Polymarket Legal in Canada 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).
