Michael Dell, the founder and chief executive of Dell Technologies, has briefly risen to become the world’s second-richest person, as a sharp rally in technology stocks and growing investor enthusiasm for artificial intelligence infrastructure pushed his personal fortune to unprecedented levels.
Dell’s net worth was estimated at about $276.5 billion on September 12, 2026, according to Forbes’ Real-Time Billionaires List. His fortune has climbed rapidly this year, reflecting the dramatic rise in the value of Dell Technologies and the broader surge in companies positioned to benefit from the global AI boom.
The latest jump has placed Dell in the company of the world’s wealthiest technology entrepreneurs, with his ranking changing rapidly as stock prices fluctuate. Forbes’ real-time estimates showed Dell’s wealth rising sharply in September, with the billionaire briefly moving into the No. 2 position before slipping down the ranking as markets moved.
Dell’s rise is particularly notable because his fortune is closely linked to a company that began as a personal-computer business but has transformed itself into a major provider of technology infrastructure. Dell Technologies has increasingly benefited from the enormous demand for servers, storage systems, networking equipment and other hardware required to operate artificial intelligence applications.
The transformation has significantly boosted the value of Dell’s stake in the company. Dell owns roughly 40% of Dell Technologies, making movements in the company’s share price directly influential on his personal wealth. Earlier in 2026, his fortune had already surged by tens of billions of dollars as investors poured money into technology stocks connected to AI.
Dell’s journey to the top of the global wealth rankings began decades ago with a much smaller venture. As a university student, he started building and selling computers from his dorm room after recognising that computers could be assembled and sold directly to customers without the traditional retail model. The business eventually became Dell Computer Corporation.
His approach helped change the personal-computer industry by allowing customers to order machines according to their requirements while keeping inventory and distribution costs relatively low. The company expanded rapidly, and Dell became one of the youngest chief executives of a Fortune 500 company.
Over the years, however, the technology industry changed dramatically. The personal-computer market matured, while demand shifted towards cloud computing, data centres and increasingly sophisticated computing infrastructure. Dell Technologies adapted by expanding beyond PCs and developing a broad portfolio of enterprise technology products.
The artificial intelligence revolution has provided another major boost. The rapid expansion of generative AI and other advanced computing applications has created enormous demand for the servers and infrastructure needed to train and operate AI models. Dell Technologies has positioned itself as a major supplier in this rapidly expanding market.
The company’s stock has consequently recorded a spectacular rise during 2026. Reports earlier this year indicated that Dell shares had climbed by more than 200%, while the company’s market value rose substantially as investors assessed its prospects in the AI infrastructure market.
Dell’s wealth is not derived exclusively from his stake in the computer company. His investments through his private investment organisation, DFO Management, as well as holdings in other technology companies, have also contributed to his fortune. His exposure to companies benefiting from the AI boom has helped amplify the gains generated by Dell Technologies.
The billionaire has also established himself as a major philanthropist. Along with his wife, Susan Dell, he has donated billions of dollars to causes including education, healthcare and children’s welfare. Their philanthropic efforts have included significant support for institutions and initiatives in the United States.
Despite his brief ascent to the second position, the global billionaire rankings remain highly volatile. The fortunes of the richest technology entrepreneurs can change by billions of dollars in a single trading session because much of their wealth is tied to publicly traded companies.
Dell’s rise nevertheless illustrates how quickly the AI boom is reshaping the global wealth hierarchy. Entrepreneurs whose companies provide the computing power, infrastructure and technology required for artificial intelligence are seeing their fortunes expand at extraordinary speed.
As of September 13, Forbes’ real-time figures put Dell’s fortune at around $276.5 billion, although his precise position among the world’s richest people can change throughout the day with movements in technology stocks.
