Highest temperature in NYC on August 16?

Platform comparison

Market context

On 16 August 2026, the highest temperature recorded at LaGuardia Airport Station will determine which Fahrenheit range this market settles into. Weather Underground's Daily Observations table—not the Day High & Low summary—serves as the binding resolution source, a distinction that matters when automated feeds and manual records diverge. The settlement window closes at 12:00 UTC on that date, meaning afternoon heat spikes after the cutoff will not factor into the outcome.

The current 0% crowd probability reflects either extreme confidence in cooler conditions or minimal trading activity in a market nearly two years forward. Historical August temperatures at LaGuardia average a high of 27°C (81°F), with extremes reaching 34°C (93°F) in notably hot years. The 2023 summer saw New York experience several days above 32°C (90°F) during mid-August, whilst 2024 patterns suggest variable conditions. Without a specific heat wave forecast or climate anomaly flagged for summer 2026, baseline expectations favour moderate rather than exceptional temperatures.

From a regulatory standpoint, this market's accessibility depends on jurisdiction and stake size. Under German GlüStV rules, prediction markets require licensing; US CFTC oversight applies to derivatives-like instruments, though small-stakes weather prediction markets often operate in grey zones. The 'no-KYC up to $1,500' threshold common on some platforms means traders can participate without identity verification below that amount, lowering friction for casual engagement. Traders should monitor National Weather Service seasonal outlooks released in July 2026 and any El Niño or La Niña declarations, as these shape August weather patterns across the north-eastern United States.

FAQ

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. Is Kalshi Legal in California 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 Kalshi Legal in California 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), Is Kalshi Legal in California would geo-block the affected region and continue processing withdrawals. Your funds remain withdrawable at any time.
