Highest temperature in Beijing on July 25?

Platform comparison

Market context

Beijing's highest temperature on 25 July 2026 will be recorded at Capital International Airport Station and resolved against historical data from Wunderground. July typically sees peak summer heat in northern China, with daily highs commonly ranging between 28–35°C, though extreme heat events can push readings above 37°C. The settlement window closes at 12:00 UTC on the day itself, meaning traders must assess seasonal and real-time meteorological conditions without post-event revision.

The 0% crowd probability reflects either extreme confidence in a specific temperature band or minimal trading activity on this particular outcome range. Historical July records for Beijing show considerable year-to-year variation; the city has recorded temperatures exceeding 40°C on rare occasions, whilst cooler summers have peaked closer to 32°C. Comparable weather markets typically see probability distributions flatten as settlement approaches, particularly when resolution depends on a single official source rather than consensus forecasts. Traders should note that Wunderground's historical data for Beijing is consistently updated and publicly accessible, reducing settlement disputes common in less-transparent weather markets.

From a regulatory standpoint, this market's accessibility depends on jurisdiction. Under Germany's GlüStV framework, weather derivatives fall outside standard gambling restrictions when structured as financial instruments, though classification remains fluid. US CFTC oversight applies to prediction markets with real-money settlement in American jurisdictions, though many platforms operate under exemptions for small-stakes markets. Platforms offering no-KYC access up to $1,500 typically treat weather markets as low-risk, since they involve no identity-linked financial instruments or sanctions exposure—though traders should verify their local regulatory environment 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.

Can I trade anonymously?

Pseudonymously, yes — up to the KYC threshold. Is Kalshi Legal in California 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. 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.

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.
