Lowest temperature in Hong Kong on July 13?

Platform comparison

Market context

On 13 July 2026, the Hong Kong Observatory will record the day's lowest temperature in degrees Celsius. This market resolves to whichever temperature band contains that single daily minimum reading, published in the Observatory's official Daily Extract once data is finalised. The settlement window closes at midday UTC on that date, though resolution itself cannot occur until the Observatory releases its records, typically within days of the observation period.

July in Hong Kong sits within the peak summer monsoon season, when daily minima rarely fall below 25–26°C even at night. Historical data from the Observatory shows that July absolute daily minimums have clustered between 24 and 27°C over recent decades, with readings below 24°C exceptionally rare. The 0% crowd probability reflects the market's design: resolution bands likely begin at thresholds (such as "below 20°C" or "20–22°C") that are meteorologically implausible for mid-summer Hong Kong. Comparable July records from 2020–2024 show no instances of minima dropping below 23°C, establishing a practical floor well above most offered ranges.

From a regulatory standpoint, this weather derivative sits within the German GlüStV framework's scope if offered to German residents, whilst US CFTC oversight applies to US persons regardless of location. The no-KYC threshold of $1,500 USD per transaction means traders in most jurisdictions can access this market without identity verification up to that stake level, though polymarket-tax.co.uk users should verify their own jurisdiction's requirements. Settlement depends entirely on Hong Kong Observatory publication; no alternative data sources or estimation methods apply.

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 Tax UK has a different geo footprint.

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.

What happens during a tax audit?

You're responsible for documenting your trades. Polymarket Tax 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.

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).
