Highest temperature in Hong Kong on August 17?

Platform comparison

Market context

On 17 August 2026, the Hong Kong Observatory will record the day's maximum temperature in degrees Celsius to one decimal place. This figure will determine which temperature band resolves as correct, with settlement finalised once the Observatory publishes its daily extract data on the specified date. The current crowd probability of 0% suggests traders have not yet committed capital to any temperature range, indicating either early-stage market formation or consensus that certain bands carry negligible likelihood.

Hong Kong's August temperatures exhibit consistent patterns shaped by the tail end of the southwest monsoon season. Historical data from the Observatory shows August daily maxima typically cluster between 31–34°C, with extreme readings above 35°C occurring in roughly 5–10% of years during this month. The 0% probability reading reflects standard market mechanics in nascent weather prediction markets rather than meteorological certainty; comparable August markets on other platforms have seen probability mass concentrate around the 32–34°C ranges once trading activity commences. August 2023 saw Hong Kong record 33.8°C as the daily maximum on the 17th, providing a recent benchmark.

Traders monitoring this market should track the Hong Kong Observatory's seasonal forecasts and any tropical cyclone activity in the Western Pacific during mid-August 2026, as storm systems can substantially suppress daily maxima. The settlement window closes at 12:00 UTC on 17 August, though final resolution depends on the Observatory's publication schedule for daily extracts, which typically occurs within 48 hours of the observation date. From a regulatory standpoint, this market operates under German GlüStV frameworks where applicable and falls within CFTC oversight for US participants; the no-KYC threshold of $1,500 USD applies to aggregate position value, meaning traders can access this specific market without identity verification provided their total exposure across all positions remains beneath that limit.

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 Kalshi Legal in California 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.

Can I trade anonymously?

Pseudonymously, yes — up to the KYC threshold. Is Kalshi Legal in California 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).
