Highest temperature in Chengdu on July 25?

Platform comparison

Market context

Chengdu will experience peak summer heat on 25 July 2026, with the settlement hinging on the single highest temperature recorded at Shuangliu International Airport Station throughout that calendar day. The resolution mechanism relies on Wunderground's historical weather database, which aggregates hourly readings into a daily maximum figure in Celsius. This is a straightforward meteorological measurement with no discretionary interpretation—the station's thermometer either reaches a given threshold or it does not.

Chengdu's July climate sits within a narrow historical band. Over the past two decades, maximum temperatures on 25 July have ranged between 28 and 35 degrees Celsius, with the city's broader July average hovering near 32 degrees. The current 0% probability assigned to the highest ranges suggests market participants expect a cooler-than-typical day, though the settlement window's two-year lead time introduces material uncertainty around long-range forecasting accuracy and potential climate variability. Comparable Asian cities at similar latitudes show July volatility of ±4 degrees from decadal means.

Traders should monitor China's meteorological authority announcements in June and early July 2026 for seasonal outlooks, particularly any El Niño or monsoon pattern shifts affecting central Sichuan Province. Real-time tracking begins approximately one week before settlement, when numerical weather models stabilise. The Wunderground data feed updates daily; any station maintenance or sensor recalibration would be documented in their metadata. From a regulatory standpoint, this market's sub-$1,500 accessibility threshold under most no-KYC frameworks (including German GlüStV exemptions for micro-stakes) means retail participation faces minimal compliance friction, though CFTC reach into US-domiciled traders remains context-dependent on the platform's jurisdiction.

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.

Do I need to KYC for Polymarket Germany Legal?

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.

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.

What if regulation changes?

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