Highest temperature in NYC on July 10?

Platform comparison

Market context

New York City is currently enduring a severe heat wave, with LaGuardia Airport hitting 104°F on 2 July 2026, surpassing its 1966 record of 101°F[9]. This extreme event frames the current 0% crowd-implied probability for lower temperature ranges on 10 July, as the market anticipates continued high heat consistent with the 73°F to 91°F daily high forecast for the month[1]. Historical data shows LaGuardia recorded a historic 94°F midnight temperature on 4 July 2026, reinforcing the likelihood that the 10 July peak will fall within the frontrunner range of 88–89°F rather than lower bands[2][4].

Traders should monitor the National Weather Service climate summaries and ongoing heat wave updates, as persistent high-pressure systems often sustain elevated temperatures through mid-July[8]. Recent reports confirm the heat wave has persisted with record-breaking readings, suggesting the settlement temperature will likely align with the 88–89°F outcome currently holding 42% probability[2][3]. The regulatory landscape adds another layer: German GlüStV implications and US CFTC reach mean accessibility depends on jurisdiction, though the platform’s ‘no-KYC up to $1,500’ threshold allows immediate participation for eligible users without identity verification[2]. This specific market remains accessible under current thresholds, provided traders comply with local gambling and tax obligations.

Can I trade anonymously?

Are prediction markets gambling?
