TL;DR
The Lee family, which controls Samsung, has doubled its wealth in twelve months, from $22.7 billion to $45.5 billion, rising from tenth place to third place among Asia’s richest families. The increase was driven by a 186% increase in Samsung Electronics’ shares of AI chip demand, and first-quarter operating profit for HBM4 memory production for Nvidia reached 57.2 trillion won (8x YoY). Meanwhile, 30,000 Samsung workers have gone on strike demanding a 15% profit share and are threatening an 18-day strike.
South Korea’s Lee family, which controls Samsung, has doubled its fortune in twelve months. Bloomberg’s Billionaires Index now estimates the dynasty’s fortunes at $45.5 billion, up from $22.7 billion a year ago, moving the Lis from tenth to third among Asia’s richest families. The catalyst is not a new product or a breakthrough in management. That’s a 186 percent jump in Samsung Electronics’ share price, driven almost entirely by global demand for high-bandwidth memory chips that power AI data centers. Samsung’s first-quarter operating profit was 57.2 trillion won, nearly eight times its revenue in the same period last year. The Li family did not build the AI industry. But the AI industry can’t function without what Samsung is building, and right now that addiction is worth $22.8 billion in new wealth per household per year.
Chip
Samsung’s financial turnaround is based on one product category: high-throughput memory, or HBM, specialized DRAM chips that sit inside GPU modules used to train and control large artificial intelligence models. Nvidia’s next-generation B300 server systems require HBM4 chips, and Samsung has entered mass production of HBM4 ahead of its main rival, SK Hynix, after years behind the technology. The change is important because HBM commands edges that conventional memory chips can’t match. When Samsung reported its first-quarter results, its semiconductor division accounted for the vast majority of profit change, turning the cyclical downturn into the company’s most profitable quarter in recent history. Nvidia’s B300 serversThe chips, which can cost more than $1 million each, are being shipped to hyperscalers and sovereign AI applications around the world, and Samsung is now one of the main suppliers of the memory these systems require.
Concentration of value in a single product line is both Samsung’s strength and weakness. HBM4 is a generational leap in memory architecture, moving from a chip-stacked DRAM design to a logic-integrated base that enables higher throughput and lower power consumption. Samsung’s ability to reach production volumes on the HBM4 ahead of its rivals gave it a price advantage that flowed directly into the first quarter’s numbers. But the AI chip supply chain is highly volatile. Nvidia’s own product cycles, the pace of data center construction by Amazon, Google, Meta and Microsoft, and geopolitical restrictions on chip exports to China determine how much HBM Samsung can sell and at what price. The stock has rallied 186 percent in twelve months on a sustained AI infrastructure boom. If the boom slows, the same leverage that doubled the Lee family’s fortune could bring it back.
Heritage
The rise in wealth reaches a critical juncture for the Lee family’s finances. The heirs of late Samsung chairman Lee Kun-hee, who died in October 2020, are paying the largest inheritance tax in South Korean history. The total liability is about 12 trillion won, roughly $9 billion at current exchange rates, and the family has agreed to pay it back in six-year installments. The last payment was made in April 2026. The tax was calculated based on the value of the estate at the time of Lee Kun-hee’s death, when Samsung’s share price was significantly lower than its current price. The family funded the payments through dividends, stock sales and loans against Samsung holdings. The timing of the share rally means that inheritance tax, once seen as a potential threat to the family’s controlling stake, has been absorbed without forcing a weakened restructuring of the group’s cross-shareholding structure. The dynasty’s control of the Samsung conglomerate remains intact.
By the standards of global technology companies, this grip is extraordinary. Samsung is not a founder-led startup or a publicly traded corporation with dispersed ownership. It is a chaebol, a family-run industrial conglomerate in which the founding family maintains control through a network of cross-shareholdings among dozens of subsidiaries. The Lee family’s direct equity stake in Samsung Electronics is relatively modest, about 5 percent of outstanding shares, but is controlled through Samsung C&T, Samsung Life Insurance and other group entities that collectively have enough voting power to determine the company’s direction. The An AI-Driven Rally in Tech Stocks inflated the value of each entity in this chain, increasing the family’s paper wealth beyond what their direct Samsung Electronics holdings alone would suggest.
Employees
The transfer of wealth to the Lee family has not gone unnoticed within Samsung. In March, nearly 30,000 members of the National Samsung Electronics Union staged a protest outside the company’s Hwasong semiconductor campus, the largest labor demonstration in the company’s history. The union demands that workers receive a share of the profits their labor produces, specifically 15 percent of the semiconductor division’s operating profit. Samsung has historically resisted union demands, and the company’s labor relations remain more adversarial than those of most large tech employers. The trade union has threatened an 18-day strike starting on May 21 if its demands are not met. Tech companies are laying off thousands of workers the reporting of record earnings is an example that goes well beyond Samsung, but the dynamics are even more acute in a chaebol structure where the controlling family’s wealth is clearly tracked and the relationship between labor and capital is unusually direct.
There is a special arithmetic of employee complaints. Samsung’s semiconductor division posted an operating profit of 57.2 trillion won in the first quarter alone. Fifteen percent of that figure is about 8.6 trillion won, or $6.3 billion, for a quarter. The union argues that the HBM4 chips that drive Samsung’s profits are produced by cleanroom workers under demanding conditions, and that the value these chips create should be distributed more widely than the current compensation structure allows. Samsung management has not publicly responded to the demand for profit sharing, but the company’s annual wage negotiations have historically ended with increases well below what the union demanded. The tension is a microcosm of a larger question that the AI boom has raised in the tech industry: when a product category reaps windfalls due to macroeconomic conditions beyond any worker’s control, who is entitled to the good?
Addiction
The fortunes of the Li family are indicative of a structural shift in the global economy. The $22.8 billion they made in the twelve months didn’t come from Samsung selling more phones, TVs or home appliances. It came from the world’s biggest technology companies, which have spent hundreds of billions of dollars on artificial intelligence infrastructure that requires a special type of memory chip manufactured by Samsung. Alphabet, Amazon, and Meta alone have spent more than $650 billion in combined AI capital in its most recent earnings, and a significant portion of these costs flow from the semiconductor supply chain to companies such as Samsung, SK Hynix and Micron. The concentration is extreme: three memory makers provide almost all the HBM chips the AI industry needs, and Samsung’s ability to scale HBM4 production has shifted its market share in the highest-margin segment at a time when demand is peaking.
This dependency goes both ways. Samsung needs an AI boom to sustain a share price that has doubled the Lee family’s wealth. The AI industry needs Samsung to produce enough HBM4 chips to keep Nvidia’s server shipments on schedule. If Samsung’s HBM4 performance suffers, data center setup is slow. If data center setup is slow, Samsung’s margins are squeezed. The A venture capital ecosystem emerging around AI infrastructure built on the assumption that computing will continue to scale, which requires memory to keep up with the scale, which requires Samsung and its competitors to continue investing in manufacturing capacity at a pace that keeps pace with demand. The Lee family’s fortune of $45.5 billion is not a static asset. This is a real-time reading of the market’s belief that the AI infrastructure cycle is years away. The family’s position as the third richest in Asia is maintained thanks to a supply chain that did not exist in its current form eighteen months ago. Dynasties are meant to be continuous. The cost of this is a function of how many GPUs Nvidia can ship in the next quarter.
