Highest temperature in NYC on August 2?

Platform comparison

Market context

The event is the highest temperature recorded at LaGuardia Airport during the day, measured in Fahrenheit and settled from the Wunderground history page for the station. Because the market resolves to a temperature band rather than an exact reading, the key question is whether the day’s peak lands inside the bands traders have priced most heavily, not whether it touches a specific number.

The current 0% YES price is best read against recent and comparable NYC heat episodes rather than a firm forecast of a cool day. New York has already had multiple very hot spells in 2026, including a 100°F reading in early July and other highs around the upper 80s to 90s, showing that extreme outcomes are plausible when synoptic heat builds over the city[6][8][18][19]. Seasonal normals are much lower, but August is still the city’s warmest period, and long-run August averages support daily highs in the upper 70s to low 80s rather than the highest heat bands[7][15]. The market’s low implied probability therefore reflects a preference for moderate bands, with only a limited tail assigned to the hottest outcomes[4].

For trading, the main catalysts are the latest forecast runs, any heat advisories from the National Weather Service, and the hourly evolution of cloud cover, humidity and sea-breeze effects that can move LaGuardia away from central Manhattan readings[16]. The market is accessible in practice only through the platform’s own rules: “no-KYC up to $1,500” means smaller positions can typically be opened without identity verification, while larger activity can trigger checks, which matters for retail participation but does not alter the settlement source. From a regulatory angle, German GlüStV rules can affect access for users in Germany, while the US CFTC has asserted broad reach over event contracts connected to US persons and US-facing markets, so account location and jurisdiction remain relevant to availability rather than to the weather outcome itself.

FAQ

Do I need to KYC for Polymarket Legal UK?

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.

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 Legal UK 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.

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), Polymarket Legal UK would geo-block the affected region and continue processing withdrawals. Your funds remain withdrawable at any time.
