Highest temperature in NYC on August 7?

Platform comparison

Market context

The key real-world question is the **highest recorded temperature at LaGuardia Airport on 7 August 2026**, with settlement driven by the Weather Underground **Daily Observations** table rather than any summary high/low display. That distinction matters because the market is tied to a station-specific reading in Fahrenheit, so late-day updates or an observational revision can matter more than the headline forecast number.[4][3]

The current **0% YES** crowd view implies the market is pricing the listed outcome bands as effectively impossible, which is a familiar pattern when a contract is still pre-event and the relevant observation window has not yet fully settled. Comparable NYC heat markets often show traders anchoring to forecast highs near 88–91°F when Bermuda High conditions dominate, but realised station maxima can differ materially by airport siting, timing of the peak, and storm timing; Weather Underground’s own page for the date is the resolution source, while the broader market page notes that revisions are considered until the first datapoint for the following date appears.[3][4][8]

From a regulatory and access angle, this sits in the usual prediction-market grey zone: German **GlüStV** rules can treat event wagering very differently from informational trading, while US **CFTC** reach is relevant where a contract may be viewed as a derivatives-style event market rather than a casual bet.[3] For accessibility, “**no-KYC up to $1,500**” typically means a user can open and trade within that cap before identity verification is requested, so small-size participation is easier than on fully verified venues, but the cap still limits exposure on a single weather outcome.[3]
