Highest temperature in Hong Kong on August 2?

Platform comparison

Market context

Hong Kong’s highest temperature on 2 August will be set by the Hong Kong Observatory’s **Absolute Daily Max** for that day, published later in its Daily Extract and measured to one decimal place in Celsius.[10] August in Hong Kong is typically hot and humid, with typical daytime highs around 31–32°C and frequent rain; recent observatory summaries show that a single hot spell can still push the monthly maximum into the mid-30s, such as 35.4°C in August 2024 and 36.3°C in August 2015.[12][9]

The **0% YES** crowd price is easiest to read as a market signal, not a weather forecast, because settlement depends on an official post-event data release rather than on any live temperature reading. For context, Hong Kong’s August records have ranged from the high 30s down to much cooler extremes over the long series, and the city has also seen very warm Augusts in recent years, including record-hitting summer conditions in 2023 and record-breaking monthly rainfall in 2025 that did not prevent high daytime maxima.[1][2][5][7] That combination means the outcome is structurally determined by the Observatory’s final bulletin, but the market can remain flat until the data are published.[10]

For accessibility, the relevant regulatory frame is mixed. Under Germany’s GlüStV, prediction-market participation can raise gambling-law questions if the product is treated as a public game of chance rather than a financial instrument, while US CFTC reach matters if a venue or participant-facing activity is considered to fall within US derivatives oversight; those are legal-characterisation issues, not weather issues. “No-KYC up to $1,500” means a user can typically trade without full identity verification until cumulative activity hits that threshold, which improves access for small positions but does not change the fact that the market only resolves once the Hong Kong Observatory finalises the 2 August extract.[10]

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 Germany Legal 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.

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), Polymarket Germany Legal would geo-block the affected region and continue processing withdrawals. Your funds remain withdrawable at any time.
