Samsung’s Lee family fortune doubles to $45.5B in AI chip boom as 30,000 workers demand profit share and threaten strike
The TL;DR
The Lee family that controls Samsung has seen its wealth double from $22.7 billion to $45.5 billion in twelve months, jumping from tenth to third among Asia’s richest families. The surge is driven by Samsung Electronics’ 186% rally in AI chip demand stocks, with Q1 operating profit reaching 57.2 trillion won (8x YoY) on Nvidia’s HBM4 memory production. Meanwhile, 30,000 Samsung workers went on strike demanding 15% of profits and threatened an 18-day strike.
South Korea’s Lee family, which controls Samsung, has doubled its fortune in twelve months. Bloomberg’s Billionaires Index now values the family’s wealth at $45.5 billion, up from $22.7 billion last year, moving the Lees from tenth to third among Asia’s richest families. The catalyst is not a new product or a management breakthrough. It’s a 186 percent increase in Samsung Electronics’ share price, driven almost entirely by global demand for high-bandwidth memory chips that power intelligence data centers. Samsung’s operating profit for the first quarter reached 57.2 trillion won, almost eight times what it earned in the same period last year. The Lee family did not build an AI factory. But the AI industry cannot function without what Samsung has built, and currently, that dependence is costing $22.8 billion in new wealth for one family in one year.
The chip
Samsung’s financial turnaround hinges on one product category: high-bandwidth memory, or HBM, special DRAM chips that sit inside GPU modules used to train and run large AI models. Nvidia’s next-generation B300 server plans require HBM4 chips, and Samsung has entered HBM4 mass production ahead of SK Hynix, its biggest rival, after years of trailing the technology. The shift is important because HBM commands margins that conventional memory chips cannot match. When Samsung reported its first-quarter results, the semiconductor division had the largest turnover in profits, turning what had been a cyclical downturn into the most profitable quarter in the company’s recent history. Nvidia’s B300 servers, which can cost more than $1 million each, are being shipped to hyperscalers and autonomous AI systems around the world, and Samsung is now one of the main suppliers of the memory those systems need.
Focusing value on a single product line is Samsung’s opportunity and its vulnerability. HBM4 is a productive leap in memory design, moving the chip from a stacked DRAM design to an integrated die base that allows for higher bandwidth and lower power consumption. Samsung’s ability to reach volume production on the HBM4 before its competitors gave it a price advantage flowed directly into the first quarter numbers. But the AI chip supply chain is notorious. Nvidia’s own product cycles, the pace of data center construction by Amazon, Google, Meta, and Microsoft, and geopolitical restrictions on chip shipments to China all determine how much HBM Samsung can sell and at what price. The stock’s 186 percent year-over-year gain on the continued growth of the AI infrastructure. If that growth slows, the same power that doubled the fortunes of the Lee family could reverse it.
Legacy
The increase in wealth comes at an opportune time for the Lee family’s finances. The heirs of late Samsung chairman Lee Kun-hee, who died in October 2020, were paying the largest inheritance tax in South Korean history. The total liability is estimated at 12 trillion won, about $9 billion at current exchange rates, which the family has agreed to pay in six annual installments. The last installment is due in April 2026. The tax was assessed on the property’s value at the time of Lee Kun-hee’s death, when Samsung’s share price was much lower than it is today. The family financed the payments through a combination of dividends, share sales, and loans from their Samsung companies. The timing of the stock rally means that inheritance tax, once seen as a major threat to the family’s controlling stake, has come in without forcing a reduced restructuring of the group’s shareholding structure. The royal hold on the Samsung conglomerate remains intact.
That adherence is unusual by the standards of global technology companies. Samsung is neither a founder-led startup nor a publicly traded company with dispersed ownership. It is a chaebol, a family-controlled industrial conglomerate in which the founding family maintains control through a web of separate stakes in many subsidiaries. The Lee family’s direct equity stake in Samsung Electronics is relatively modest, about 5 percent of the outstanding shares, but its control is exercised by Samsung C&T, Samsung Life Insurance, and other group entities that hold sufficient voting power to determine the company’s direction. The AI-driven rally in technology stocks has increased the value of every organization in the chain, increasing the wealth of the family’s papers beyond what their Samsung Electronics alone can 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 gathered outside the company’s Hwaseong semiconductor campus, the largest demonstration in the company’s history. The union wants workers to receive a share of the profits they produce, specifically a bonus corresponding to 15 percent of the operating profits of the semiconductor division. Samsung has historically resisted union demands, and the company’s labor relations remain more adversarial than those of most tech employers. The union has threatened an 18-day strike from May 21 if its demands are not met. Tech companies cutting thousands of jobs while reporting record profits is a pattern that goes beyond Samsung, but the power is sharper in the chaebol structure where the ruling family’s wealth is publicly tracked and the connection between workers and money is unusually direct.
The workers’ complaint has some arithmetic. Samsung’s semiconductor division generated 57.2 trillion won in operating profit in the first quarter alone. Fifteen percent of that figure is roughly 8.6 trillion won, or $6.3 billion, in one quarter. The union says the HBM4 chips that drive Samsung’s profits are produced by clean-room workers under harsh conditions, and that the value of those chips it creates should be distributed more widely than the current compensation structure allows. Samsung executives have not publicly responded to the specific profit-sharing request, but the company’s annual wage negotiations have historically ended with less than the union’s requested increase. The tension is a microcosm of the broader question that the AI boom raises across the technology spectrum: when one product category generates rapid profits due to macroeconomic conditions beyond the control of any individual worker, who has the right to rise?
Dependence
The fortune of the Lee family is representative of the structural change in the world economy. The $22.8 billion they earned in twelve months didn’t come from Samsung selling more phones, televisions, or accessories. It comes from the world’s largest technology companies spending hundreds of billions of dollars on AI infrastructure that requires a specific type of memory chip manufactured by Samsung. Alphabet, Amazon, and Meta alone have directed more than $650 billion in AI capital spending in recent earnings, and much of that money is flowing through the semiconductor supply chain at companies like Samsung, SK Hynix, and Micron. Concentration is extreme: three memory manufacturers provide almost all the HBM chips the AI industry needs, and Samsung’s ability to achieve HBM4 production at scale has changed its market share in the high-margin segment at a time when demand is at its peak.
That dependence goes in both directions. Samsung needs an AI boom to maintain a share price that doubles the Lee family’s fortune. The AI industry needs Samsung to produce enough HBM4 chips to keep Nvidia’s server shipments up to date. If Samsung’s HBM4 is producing sluggishly, data center construction is slowing down. When data center construction slows, Samsung’s margins are squeezed. The venture capital ecosystem that has sprung up around AI infrastructure is built on the assumption that computing will continue to scale, which requires memory to continue to scale, which requires Samsung and its competitors to continue to invest in capacity to keep pace with demand. The Lee family’s fortune of $45.5 billion is not static. A real-time reading of market confidence is that the AI infrastructure cycle is years away. The position of the family, the third richest in Asia, was held due to an unprecedented buying spree eighteen months ago. Dynasties should last a long time. The amount of this is a function of how many GPUs Nvidia can ship in the next quarter.
