Michael Dell’s fortune nearly doubled to $262 billion as Dell Technologies became a major supplier of AI infrastructure, but he fell to No. 4 on Forbes’ Real-Time Billionaires list after the company’s shares dropped more than 6% amid a broader AI-stock selloff. Dell, who owns roughly 40% of the company, gained about $122 billion since this time in 2025, according to the Bloomberg Billionaires Index. Dell Technologies reported record second-quarter fiscal 2027 revenue of $47 billion on Sept. 1, up 58% year over year, while AI-optimized server revenue reached $16.4 billion, up from $8.2 billion. Its latest fiscal 2027 forecast calls for $74 billion in AI-optimized server revenue, compared with an earlier $60 billion forecast and $25 billion in the previous fiscal year. Dell briefly became the world’s third-richest person on Sept. 8 and second-richest on Sept. 9, passing Larry Page, before the latest decline.
