Highest temperature in NYC on July 21?

Platform comparison

Market context

On 21 July 2026, the highest temperature recorded at LaGuardia Airport Station will fall within one of several defined ranges, measured in degrees Fahrenheit. The National Weather Service operates the official observation equipment at this location, and historical records from Weather Underground provide the settlement baseline. New York City's July temperatures typically range from 75 to 88 degrees Fahrenheit, though heat waves can push readings into the low 90s. The current crowd probability of 0% assigned to this market reflects the inherent difficulty in forecasting a specific day's peak temperature nearly two years in advance, where seasonal norms offer limited predictive power.

LaGuardia's historical July data shows considerable year-to-year variation. The station recorded 96°F on 9 July 2019 and 91°F on 21 July 2019, illustrating how the same calendar date can experience markedly different conditions. Traders assessing this market should note that mid-to-late July typically sits near the peak of New York's summer heat season, though the Atlantic hurricane season's influence and upper-level atmospheric patterns remain unpredictable at such distance. The settlement window closes at 12:00 UTC on the resolution date, meaning the highest temperature recorded across the full 24-hour period at LaGuardia determines the outcome.

From a regulatory standpoint, this market operates under frameworks including the German GlüStV where applicable to EU traders, whilst US CFTC oversight applies to American participants. Most prediction market platforms offer no-KYC access up to approximately $1,500 in cumulative position value, permitting casual participation without identity verification below that threshold. This accessibility structure applies equally to weather markets, though traders should verify their platform's specific terms before committing capital.

FAQ

Can I trade anonymously?

Pseudonymously, yes — up to the KYC threshold. Is Polymarket Legal in Canada 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 Polymarket Legal in Canada 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).

What if regulation changes?

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