Highest temperature in Houston on July 10?

Platform comparison

Market context

The market hinges on the highest temperature recorded at William P. Hobby Airport in Houston on 10 July 2026, measured in degrees Fahrenheit. With the crowd-implied probability for a "YES" outcome at 0%, the current consensus suggests the event will not occur, though the specific temperature range defining "YES" remains unstated in the prompt. Historical July data for Houston shows average highs near 93°F, with recent 2026 forecasts indicating daily highs between 85°F and 96°F, staying below the century mark despite a building heat dome [2][9].

Comparable cases from recent years show Houston frequently reaching 95–97°F in mid-July, with extremes occasionally hitting 100°F, though 2026 has not yet recorded a 100-degree day [9]. The 0% probability likely reflects a specific threshold (e.g., above 100°F) that current forecasts deem unlikely, given the heat dome is expected to keep temperatures shy of that mark [9]. Traders should monitor the National Weather Service’s daily updates for the Houston area and any sudden shifts in the heat dome’s intensity, as scattered storms reported on 10 July could temporarily suppress peak temperatures [8].

Regulatory accessibility is shaped by the German GlüStV, which restricts unlicensed betting, and US CFTC reach, which governs commodity-based prediction markets. The "no-KYC up to $1,500" provision allows traders to access this weather market without identity verification for smaller stakes, enhancing accessibility while remaining within compliance boundaries for this specific event. This structure aligns with iskals legal frameworks for prediction markets operating across jurisdictions.
