Highest temperature in NYC on August 11?

Platform comparison

Market context

On 11 August 2026, the highest temperature recorded at LaGuardia Airport Station will determine this market's resolution, with Weather Underground's Daily Observations table serving as the authoritative source rather than any summary high-low figures. The settlement window closes at 12:00 UTC that day, capturing the full diurnal cycle of New York City's summer weather. Current crowd pricing reflects near-zero probability across all temperature bands, suggesting either extreme confidence in a narrow outcome or insufficient liquidity to establish meaningful odds.

Historical August temperatures at LaGuardia show a median daily high around 82–84°F, with extremes ranging from 96°F (recorded in 2021) down to 68°F in cooler years. The 0% implied probability across all ranges is atypical for weather markets and may indicate sparse trading activity rather than genuine certainty; comparable August markets typically distribute probability across 5–10°F bands. Traders should recognise that summer heat waves in the Northeast remain meteorologically plausible, particularly given recent decadal warming trends documented by NOAA.

From a regulatory standpoint, this market's accessibility depends on jurisdiction. Under German GlüStV rules, prediction markets operating without a licence face restrictions, though some EU platforms operate under exemptions for small-stake trading. In the United States, CFTC oversight applies to derivatives on weather indices, though many platforms claim exemptions for non-leveraged binary contracts. Platforms offering no-KYC access up to $1,500 typically operate under safe-harbour provisions, meaning traders can participate without identity verification below that threshold—a material consideration for retail participation in weather prediction markets.

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.

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 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.
