Highest temperature in NYC on August 25?

Platform comparison

Market context

Late-summer heat in New York City is the underlying event, with settlement tied to NOAA’s highest hourly temperature reading at LaGuardia Airport on 25 August 2026. The market uses the NOAA timeseries page for KLGA and the “Temp” column on the hourly data view, so the relevant number is the day’s observed maximum, not the forecast high or a city-wide average.

A 0% implied probability points to either stale pricing, a market already effectively past resolution, or a contract structure that is being read as near-certain to settle outside the YES band. For comparison, late-August maxima in New York often sit in the upper 70s to upper 80s Fahrenheit, with brief spikes into the 90s during warm, humid spells; that makes the exact bucket sensitive to whether a front, sea breeze, or afternoon convection trims the peak by even a degree or two. The practical read is that terminal value usually turns on a short-lived midday or early-afternoon observation rather than an all-day average.

On access and regulation, the framing matters: under Germany’s GlüStV regime, prediction-market participation can raise gambling-law and geo-blocking issues for German users, while US venues continue to argue that the CFTC has exclusive federal reach over event contracts and can pre-empt state interference[2][3]. “No-KYC up to $1,500” generally means lower-friction entry for small balances, but it does not remove residency screens, sanctions checks, or platform limits; it simply indicates that lighter identity verification may apply below that threshold, which can broaden access for some users while still excluding restricted jurisdictions[1][2][3].
