Highest temperature in Hong Kong on June 5?

Market context

On 5 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 date.

Hong Kong's June temperatures historically range between 28–35°C, with the absolute maximum on record for early June reaching 36.1°C in 2015. The current 0% crowd probability suggests traders expect the temperature to fall outside whichever range options are available in this market's structure. Historical volatility in early June reflects the transition into the southwest monsoon season; heat spikes occur but are not dominant. Comparable markets on Hong Kong Observatory data have resolved reliably based on published daily extracts, with minimal disputes over source material or measurement methodology.

Traders should monitor the Hong Kong Observatory's seasonal forecasts and any tropical cyclone warnings issued in late May or early June, as these significantly influence temperature patterns. The market's accessibility depends on jurisdiction: under German GlüStV regulations, prediction markets require licensing; US CFTC reach extends to US persons regardless of location; however, many platforms offer no-KYC access up to $1,500 notional exposure, which may permit participation in this specific market without identity verification below that threshold. Actual regulatory treatment varies by platform 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.

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.

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.

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.
