Highest temperature in NYC on August 3?

Platform comparison

Market context

The event is the **highest recorded temperature at LaGuardia Airport on 3 August 2026**, which will be settled against Wunderground’s daily history page for KLGA rather than citywide averages or a generic New York reading. Because the market resolves to a temperature *range*, traders are effectively pricing where the day’s peak observation will land, not whether the afternoon will feel hot in Manhattan.

The current **0% YES** crowd price is best read as a stale or structurally cautious signal rather than a weather forecast on its own. Comparable New York temperature markets often cluster tightly around nearby bands when guidance is in the low-to-mid 80s Fahrenheit, and even a small shift in forecast highs can move the most likely bucket materially. For context, recent market and forecast material has pointed to New York highs in the low 80s, with one event page showing 82–85°F as the leading zone and official forecast products also calling for warm August conditions in the city.

For accessibility, the regulatory frame matters as much as the weather. Under Germany’s **GlüStV**, prediction-market access can be affected by gambling-law restrictions, so availability for German users may be limited even when a venue is open elsewhere. In the US, the **CFTC** has reach over listed derivatives and event contracts, so venue structure and jurisdiction remain relevant to how such markets are offered. A **no-KYC up to $1,500** policy generally means smaller-volume participation can occur without full identity verification, which lowers friction for casual traders but still leaves larger activity subject to enhanced checks and venue controls.

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. Is Kalshi Legit has a different geo footprint.

Can I trade anonymously?

Pseudonymously, yes — up to the KYC threshold. Is Kalshi Legit 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 Legit 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 Legit would geo-block the affected region and continue processing withdrawals. Your funds remain withdrawable at any time.
