Lowest temperature in Hong Kong on July 13?

Platform comparison

Market context

On 13 July 2026, the Hong Kong Observatory will record the day's lowest temperature in degrees Celsius. This market resolves based on the official "Absolute Daily Min" figure published in the Observatory's Daily Extract once data is finalised, measured to one decimal place. The settlement window closes at 12:00 UTC on that date, though resolution may be delayed pending official publication of meteorological records.

Hong Kong's July climate presents a narrow band of outcomes. Historical data shows minimum temperatures in mid-July typically range between 24–27°C, with the city's subtropical monsoon pattern producing consistent overnight lows during the summer season. The 0% crowd probability suggests traders are pricing in either extreme confidence in a specific temperature band or uncertainty about which range will ultimately contain the recorded minimum. Comparable July days from prior years provide the most reliable baseline for assessing plausible outcomes, though individual daily variation remains material.

From a regulatory standpoint, this weather derivative falls within the German GlüStV framework's scope for prediction markets, whilst US CFTC reach extends to US-based traders regardless of settlement currency or location. The no-KYC threshold of $1,500 applies to aggregate positions on this platform, meaning traders can access this market without identity verification up to that cumulative exposure limit. Beyond that threshold, standard KYC documentation becomes mandatory. Settlement depends entirely on Hong Kong Observatory publication timelines, which typically occur within 48 hours of the observation date but may extend if data validation is required.

FAQ

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.

What happens during a tax audit?

You're responsible for documenting your trades. Is Kalshi Legal in California 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).
