Highest temperature in Hong Kong on June 2?

Platform comparison

Market context

On 2 June 2026, the Hong Kong Observatory will record the highest temperature in degrees Celsius for that day. This market resolves based on the official "Absolute Daily Max" figure published in the Observatory's Daily Extract, measured to one decimal place. The settlement window closes at 12:00 UTC on that date, though resolution cannot occur until the Observatory publishes finalised data, typically within days of the observation period.

Hong Kong's June temperatures historically cluster between 28–32°C for daily maxima, though extremes have reached 35°C during heat waves. The 0% crowd probability suggests traders currently perceive no meaningful likelihood of the market resolving to any specific temperature band, which may reflect uncertainty about which ranges are actually offered or sparse trading activity. Comparable weather markets on established platforms show that temperature predictions within seasonal norms typically attract modest participation, whilst extreme-weather scenarios generate sharper probability shifts.

From a regulatory standpoint, this market's accessibility depends on jurisdiction. Under German GlüStV rules, prediction markets require licensing; under US CFTC oversight, certain weather derivatives face restrictions unless properly registered. Many platforms offer no-KYC access up to $1,500 notional exposure, which would permit participation in this market without identity verification for traders staying below that threshold. Traders should verify their platform's specific regulatory status and KYC requirements before placing positions, as these vary significantly by operator and user location.

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. PolyGram has a different geo footprint.

What happens during a tax audit?

You're responsible for documenting your trades. PolyGram 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).

What if regulation changes?

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