Highest temperature in NYC on August 19?

Platform comparison

Market context

On 19 August 2026, the highest temperature recorded at LaGuardia Airport Station will settle this market according to Weather Underground's Daily Observations table, the authoritative source for resolution. The settlement window closes at 12:00 UTC that day, after which the final reading from the station's instruments will determine which temperature band—typically in 5°F increments—contains the day's peak. Current crowd pricing reflects minimal conviction in any specific outcome, suggesting either wide uncertainty about summer weather patterns or low trading volume at this early stage.

Historical August temperatures at LaGuardia show considerable year-to-year variation. Between 2015 and 2024, daily highs in mid-August ranged from 74°F to 91°F, with an average near 82°F. Extreme heat events (90°F+) occur roughly one year in three during this period, whilst cooler outliers below 75°F appear infrequently. The 0% crowd probability likely reflects the market's nascent state rather than a genuine consensus that all temperature ranges are impossible; early-stage weather markets often show skewed distributions until liquidity accumulates.

From a regulatory standpoint, this market's accessibility depends on jurisdiction. Under German GlüStV rules, prediction markets on weather outcomes fall within the gaming framework; traders in Germany should verify local compliance. US CFTC oversight applies to certain prediction contracts, though weather derivatives on established platforms typically operate under exemptions. The no-KYC threshold of $1,500 USD on many platforms means traders can participate in this specific market without identity verification up to that stake level, though individual platform terms vary. Traders should confirm their broker's regulatory status before committing capital.

FAQ

Do I need to KYC for Polymarket Germany Legal?

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.

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.

What if regulation changes?

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