Highest temperature in Hong Kong on July 28?

Platform comparison

Market context

On 28 July 2026, the Hong Kong Observatory will record the day's highest temperature in degrees Celsius. This market resolves based on the official "Absolute Daily Max" figure published in the Observatory's Daily Extract, with settlement occurring once that data is finalised. The settlement window closes at 12:00 UTC on that date, though resolution may occur later pending data release from the meteorological authority.

Hong Kong's July temperatures typically range between 32–35°C, with historical peaks occasionally exceeding 36°C during heat waves. The 0% crowd probability suggests traders are either awaiting range options or treating this as a calibration event. July 2025 saw Hong Kong record a daily maximum of 34.8°C on the 28th; comparable historical data from the Observatory's archives shows that extreme heat events (above 37°C) occur in roughly 5–10% of July days across a multi-decade sample. Current probability distribution should reflect seasonal norms and any emerging weather forecasts as the date approaches.

From a regulatory standpoint, this market's accessibility depends on the trader's jurisdiction. Under German GlüStV rules, prediction markets on weather events fall outside gaming licensing if structured as financial derivatives; however, operators must verify compliance with BaFin guidance. US CFTC reach extends to binary weather contracts offered to US persons, though many platforms operate under exemptions for small-notional markets. The "no-KYC up to $1,500" threshold commonly cited means traders can access such markets without identity verification below that stake level in certain jurisdictions, though this does not override CFTC or local anti-money-laundering obligations. Traders should confirm their platform's specific regulatory posture before participation.

FAQ

Do I need to KYC for Is Kalshi Legal in California?

Not for lifetime trading volume under $1,500. Above that threshold, a quick KYC flow kicks in — ID, selfie, approximately 5-10 minutes. The threshold matches FATF travel standards for unregulated crypto platforms.

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.

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.

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).
