Highest temperature in Hong Kong on August 12?

Platform comparison

Market context

On 12 August 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 dataset, with settlement occurring once that data is finalised. The 0% crowd probability reflects the market's current state rather than any meteorological certainty; August temperatures in Hong Kong are well-established phenomena with measurable historical ranges.

Hong Kong's August climate is characterised by monsoon influence and high humidity, with daily maxima typically ranging between 31–34°C. The Observatory's historical records show August peaks occasionally reaching 35°C or higher during heat waves, though such extremes remain statistically infrequent. Comparable August dates from recent years provide calibration points: traders should review the Observatory's archived Daily Extracts to assess how often specific temperature thresholds have been exceeded. The current zero probability likely reflects early-stage market formation rather than predictive consensus.

From a regulatory standpoint, this weather derivative falls within differing jurisdictional frameworks depending on trader location. The German GlüStV (gambling licensing statute) treats prediction markets as gaming contracts, requiring operator licensing. US CFTC oversight applies to certain derivatives but typically exempts binary weather outcomes under specific conditions. The "no-KYC up to $1,500" threshold common on some platforms means traders can participate in this market without identity verification if their position size remains below that limit, though operators must verify this applies to their jurisdiction and the specific contract structure. Traders should confirm their platform's compliance posture before trading.

FAQ

Is Polymarket legal in my country?

What happens during a tax audit?

Are prediction markets gambling?

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?
