Highest temperature in Hong Kong on July 24?

Platform comparison

Market context

The real-world event here is the highest temperature recorded by the Hong Kong Observatory on 24 July, measured in degrees Celsius and published later in the final daily extract. July in Hong Kong is typically hot, humid and unsettled, with heavy rainfall common alongside high daytime temperatures, so the market is really about where the day’s peak sits within the Observatory’s published range rather than any single forecast reading.[1]

A 0% crowd-implied probability for the top outcome can be read as a market view that the extreme upper band is very unlikely, but it also reflects how these weather markets often price in late-day uncertainty and the lag before the Hong Kong Observatory finalises its data. Comparable summer Hong Kong temperature outcomes are usually constrained by cloud cover, rain and tropical weather patterns, which tend to keep maxima below the most aggressive bands even when conditions feel hot at street level.[1]

For accessibility, the practical question is less the weather itself than the regulatory wrapper. If the venue is offered through a platform operating under German GlüStV exposure, access can depend on local gambling restrictions and product classification; in the US, CFTC reach matters if the market is deemed a derivatives-style contract rather than a pure betting product. The “no-KYC up to $1,500” feature means a user may be able to trade small amounts without full identity verification, but that is an account-access threshold, not a guarantee of unrestricted availability for residents in every jurisdiction, and it does not change how the contract settles to the Hong Kong Observatory’s published figure.

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 Legal UK has a different geo footprint.

Can I trade anonymously?

Pseudonymously, yes — up to the KYC threshold. Polymarket Legal UK 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.

What happens during a tax audit?

You're responsible for documenting your trades. Polymarket Legal 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).
