AI’s hidden billionaires: How the infrastructure boom is creating a new class of wealth

Artificial intelligence is often discussed through the lens of software. Public attention focuses on large language models, generative AI applications, autonomous systems, and the technology giants developing them. Yet behind every AI system sits an immense physical infrastructure of data centres, semiconductor supply chains, power systems, networking equipment, cooling technologies, and precision-manufactured components. As companies race to expand their AI capabilities, a different group of corporate winners is emerging: the firms supplying the physical foundations upon which artificial intelligence depends.

According to analysis by investment research platform BestBrokers, the technology sector added more than $1 trillion in billionaire wealth between July 2025 and July 2026, making it the most profitable sector globally for ultra-high-net-worth individuals. The findings point not only to the growing importance of AI, but also to the industries quietly benefiting from the infrastructure required to support it.

The analysis, based on data from the Forbes Real-Time Billionaires List, found that technology remains the largest billionaire-producing sector globally. By July 2026, the technology industry counted 511 billionaires with a combined wealth of $5.30 trillion. This represented an increase of approximately $1.02 trillion compared with the previous year.

Such growth reflects the massive investments currently flowing into AI infrastructure. Amazon, Alphabet, Microsoft and Meta have collectively committed hundreds of billions of dollars towards expanding data centre capacity, cloud infrastructure, advanced computing resources and AI deployment. The wealth generation has been highly concentrated. According to the report, more than half of the technology sector’s entire increase in billionaire wealth came from three individuals alone: Elon Musk, Michael Dell and Larry Page.

This concentration illustrates one of the defining features of modern technology markets. While innovation can create enormous economic value, that value often flows disproportionately towards a relatively small number of founders, investors and executives.

The unexpected AI winners

Perhaps the most interesting finding from the report is the performance of the manufacturing sector. Manufacturing ranked second among all industries, with 408 billionaires collectively adding $328.3 billion to their fortunes over the twelve-month period. This result challenges the common perception that AI is purely a software-driven phenomenon.

Alan Goldberg of BestBrokers argues that manufacturers are increasingly supplying the essential hardware components required for AI deployment. Server racks, cable management systems, cooling technologies, metal assemblies and precision-engineered components may not attract the headlines associated with AI chatbots, but they remain indispensable.

A particularly notable example is Taiwan-based King Slide Works. Originally known for manufacturing furniture rail systems, the company has benefited significantly from demand for data centre infrastructure. Its products now include server rail kits and cable management solutions used in large-scale computing facilities. The example highlights a broader trend: many traditional industrial firms are finding new markets through AI-related infrastructure spending.

Another standout sector is cryptocurrency and blockchain. Despite containing only 18 billionaires, the sector generated the fourth-highest increase in billionaire wealth overall. Combined net worth rose from approximately $189.8 billion in 2025 to $346.6 billion in 2026. Interestingly, much of this growth did not stem from speculative cryptocurrency trading or token appreciation. Instead, the gains were largely concentrated within leadership linked to Tether, the world’s largest stablecoin issuer.

According to the report, executives including Giancarlo Devasini, Jean-Louis van der Velde, Paolo Ardoino, and Stuart Hoegner collectively added around $143.4 billion to their fortunes.

This may indicate a shift within the digital asset industry. Rather than relying solely on trading activity, stablecoin providers are increasingly functioning as financial enterprises generating income from reserve assets and associated services. If so, the evolution of stablecoins could represent a maturation of the cryptocurrency sector, moving beyond its origins as a speculative asset class.

Physical infrastructure

One of the most significant messages emerging from the analysis is that AI’s economic impact extends well beyond software developers. Every AI query requires data centre capacity, for example, along with electricity generation, cooling systems, and fibre-optic connectivity.  As a result, industries that historically received relatively little attention from technology investors are finding themselves at the centre of one of the largest infrastructure expansions in modern economic history.

For investors, focusing exclusively on AI software companies may provide an incomplete picture of where value is being created. Many of the largest gains appear linked to firms supporting the ecosystem rather than directly delivering AI applications. A data centre vendor, for example, may profit regardless of which AI model ultimately wins market share

Not every industry has benefited

While many sectors saw substantial gains, the report also identified areas where billionaire wealth declined. Consumer Products and Media & Entertainment were the only industries to record net reductions in combined wealth between 2025 and 2026. Consumer Products billionaires experienced a collective decline of approximately $2.6 billion. A significant contributor was Chen Zhiping, chairman of Smoore International, whose net worth reportedly fell as the valuation of the company’s vaping-device business decreased.

The Media & Entertainment sector performed even worse, declining by approximately $6.8 billion. Much of this reduction was associated with the Thomson family and their holdings connected to Thomson Reuters. The report suggests investor concerns regarding the impact of AI on legal-information and professional-services markets contributed to valuation declines.

This trend illustrates the disruptive side of artificial intelligence. While many organisations are benefiting from AI adoption, others are facing questions about how AI could alter traditional business models.
