Highest temperature in NYC on July 4?

Platform comparison

Market context

The real-world event driving this market is the highest temperature recorded at LaGuardia Airport on 4 July 2026, with settlement dependent on Wunderground data. Current crowd-implied probability sits at 0% YES, suggesting traders believe the temperature will not exceed the defined threshold, despite recent heat anomalies.

Historical context frames this probability: LaGuardia recorded 94°F at midnight into 4 July 2026, the city’s warmest midnight on record, surpassing the 93°F peak from 2013[1][3]. Daily highs earlier in the week hit 104°F, exceeding the 1966 record of 101°F[4]. Such extremes indicate that while midnight temperatures are high, daytime peaks remain the critical variable for this market’s resolution.

Traders should monitor immediate weather catalysts, including forecasts for showers and thunderstorms before 2am on 4 July, which could suppress daytime highs[7]. The National Weather Service predicts a high of 92°F for Independence Day, though storm activity remains a dependency[7]. Recent reports confirm storms are possible for July 4th in New York, a key factor to watch as settlement approaches[8]. Regulatory accessibility hinges on German GlüStV implications and US CFTC reach; the “no-KYC up to $1,500” threshold allows broader participation without identity verification, enhancing liquidity for this specific weather event.

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.

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.

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).
