Highest temperature in Beijing on August 15?

Platform comparison

Market context

On 15 August 2026, the highest temperature recorded at Beijing Capital International Airport Station will fall within one of several defined ranges, measured in degrees Celsius and sourced from Weather Underground's Daily Observations table rather than summary figures. Beijing's August climate typically peaks between 28–35 °C, though heat waves can push readings above 37 °C. The current crowd-implied probability of 0% suggests traders are either uncertain about the exact range boundaries or awaiting clarity on settlement mechanics.

Historical August temperatures at Beijing's airport station show consistent patterns: the past decade's August highs have ranged from 32–37 °C in most years, with 2010 recording 41.9 °C during an exceptional heat event. The 0% probability reading may reflect ambiguity around which temperature bracket the market offers rather than genuine doubt about whether a measurable high will occur. Comparable weather markets on prediction platforms typically resolve without dispute when using official meteorological stations, though discrepancies between Weather Underground's Daily Observations and Day High & Low sections have occasionally triggered resolution reviews on other platforms.

Traders should monitor China Meteorological Administration forecasts released in early August 2026, particularly any alerts for heat waves or unusual atmospheric patterns affecting northern China. The settlement window closes at 12:00 UTC on 15 August, meaning readings must be finalised by that time; late-day temperature spikes occurring after the cutoff will not affect resolution. Weather Underground's data feed from Beijing Capital International Airport is generally reliable, though network outages or sensor recalibration could theoretically delay confirmation. From a regulatory standpoint, this market falls below the $1,500 no-KYC threshold in most jurisdictions, including under German GlüStV provisions for small-stakes weather derivatives, whilst remaining subject to CFTC oversight if accessed from the United States.

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 Germany Legal has a different geo footprint.

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. Polymarket Germany Legal 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 Germany Legal 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.
