Highest temperature in NYC on July 3?

Platform comparison

Market context

The underlying event is the highest temperature recorded at LaGuardia Airport on 3 July 2026, measured in degrees Fahrenheit and sourced from Wunderground. This single data point will determine the market resolution, with the settlement window closing at 12:00 UTC on 3 July 2026. Current crowd-implied probability sits at 0% for the YES outcome, suggesting traders believe the temperature will fall outside the specific range being offered.

Historical precedents frame this probability sharply, as LaGuardia has previously recorded extreme highs during July heatwaves. In 1966, the station hit 107°F on 3 July, while a recent heatwave in July 2026 saw LaGuardia reach 104°F on 2 July, surpassing its 1966 daily high of 101°F[3]. Such volatility indicates that a 0% probability may be premature if the range excludes these known extremes, as similar dates have consistently breached 100°F in recent years[2].

Traders should monitor daily heatwave announcements and the National Weather Service forecast schedules, which often update dependency models for urban heat retention. A recent Yahoo News report highlighted dangerous, record-breaking heat as possible across New York and New Jersey, noting that 107°F was set at LaGuardia on 3 July 1966, a critical benchmark for this market[8]. Regulatory accessibility remains a factor, as German GlüStV implications and US CFTC reach define compliance, while the "no-KYC up to $1,500" threshold allows immediate participation without identity verification for this specific weather event.

FAQ

Do I need to KYC for Polymarket Tax 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.

Can I trade anonymously?

Pseudonymously, yes — up to the KYC threshold. Polymarket Tax 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.

What happens during a tax audit?

You're responsible for documenting your trades. Polymarket Tax UK exports a full transaction history (CSV/PDF) for tax reporting. In an audit you'll need to present these documents.

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).

What if regulation changes?

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