Highest temperature in Shanghai on August 16?

Platform comparison

Market context

On 16 August 2026, Shanghai Pudong International Airport Station will record a daily maximum temperature. This market resolves to whichever temperature band contains the highest reading logged in Weather Underground's Daily Observations table on that date, with the Observations data taking precedence over any summary figures should discrepancies arise. The settlement window closes at 12:00 UTC on the resolution date.

August in Shanghai typically sees daily highs between 32–35°C, with occasional peaks above 36°C during heat waves. Historical data from the past decade shows that extreme temperatures—those exceeding 38°C—occur in roughly 15–20% of August days at Pudong, usually driven by high-pressure systems stalled over eastern China. The current crowd probability of 0% suggests traders are pricing in either a narrow temperature band or confidence in moderate conditions for that specific date. Comparable August days in 2023 and 2024 saw highs of 33–34°C under typical monsoon influence, providing a baseline against which outlier scenarios should be weighed.

Traders monitoring this market should track China's meteorological forecasts from late July onwards, particularly alerts from the China Meteorological Administration regarding heat waves or tropical cyclone activity in the East China Sea. Summer typhoon season peaks in August, and any system approaching the Yangtze River Delta region could suppress temperatures significantly. Additionally, the Shanghai Municipal Government occasionally issues heat warnings when forecasts exceed 37°C, which may correlate with observable shifts in betting patterns. From a regulatory standpoint, this market operates under German GlüStV rules where applicable, with US CFTC oversight limited to US-domiciled traders; the no-KYC threshold of $1,500 applies to aggregate positions across all weather markets on this platform, meaning traders can access this specific contract without identity verification provided cumulative exposure remains below that limit.

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.

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).

What if regulation changes?

If regulation changes in your jurisdiction (e.g. prediction markets are banned), Is Kalshi Legal in California would geo-block the affected region and continue processing withdrawals. Your funds remain withdrawable at any time.
