Highest temperature in NYC on July 9?

Platform comparison

Market context

The underlying event is the highest temperature recorded at LaGuardia Airport on 9 July 2026, a date that has already passed in the real world with settlement fixed for 12:00 UTC on 9 July 2026. Historical precedent shows LaGuardia reached 104°F on 2 July 2026, breaking the 1966 record of 101°F by 3 degrees, while midnight temperatures hit 94°F on 4 July 2026, the station’s highest ever at that hour[2][4]. Given that July 2026 has already produced unprecedented heat across a 500-mile East Coast corridor, killing 29 people in New Jersey and shattering records standing for up to 154 years, the crowd-implied 0% probability for any specific high range suggests traders are either misreading the settlement timing or assuming the peak heat has already passed[2].

Traders must monitor the official Wunderground resolution source, which will publish the day’s maximum temperature for LaGuardia, and verify whether the 9 July reading matches or exceeds the 2 July peak of 104°F[2]. Recent reports confirm LaGuardia’s heat wave persisted through the weekend, with midnight temperatures remaining at 94°F into 4 July, indicating sustained thermal stress that could elevate the 9 July maximum[5][7]. The settlement window closes 12:00 UTC on 9 July 2026, meaning the data is already available; accessibility hinges on regulatory frameworks like Germany’s GlüStV, which may restrict participation, and US CFTC reach, which could impose KYC requirements for markets exceeding $1,500, though “no-KYC up to $1,500” allows immediate entry for smaller positions without identity verification[2].

This market’s 0% probability likely reflects confusion over the settlement date rather than a lack of heat, as July 2026 has already delivered record-breaking temperatures across the region[2]. The resolution will depend solely on Wunderground’s published maximum for 9 July, and traders should confirm whether the 9 July reading aligns with the 2 July peak or shows a decline following the holiday weekend’s extreme heat[2][4]. Regulatory clarity on GlüStV and CFTC rules will determine whether participants can access the market without KYC, with the $1,500 threshold enabling immediate, unrestricted entry for smaller trades[2].

FAQ

Is Polymarket legal in my country?

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.

Are prediction markets gambling?

Is there a withdrawal cap?
