The wealth of Samsung's Lee family has increased to $45.5 billion due to the surge in AI chip demand, while 30,000 employees are calling for a share of the profits and have threatened to strike.

      TL;DR: The Lee family, which oversees Samsung, has seen its wealth surge from $22.7 billion to $45.5 billion within a year, elevating them from the tenth to the third richest family in Asia. This growth is attributed to a 186% increase in Samsung Electronics’ stock price driven by soaring demand for AI chips. The company's Q1 operating profit reached 57.2 trillion won (an eightfold increase year-over-year), largely due to HBM4 memory production for Nvidia. However, 30,000 Samsung employees are demanding a 15% share of the profits and have threatened to strike for 18 days.

      The Lee family of South Korea, which controls Samsung, has doubled its wealth over the past year. According to Bloomberg’s Billionaires Index, the family's holdings are now valued at $45.5 billion, up from $22.7 billion, moving them from tenth to third among Asia’s richest families. This increase is not due to any new product or management innovation but rather a 186% rise in Samsung Electronics’ stock, primarily fueled by global demand for the high-bandwidth memory chips essential for AI data centers. Samsung's operating profit for Q1 hit 57.2 trillion won, approximately eight times higher than the previous year. The Lee family did not create the AI sector; however, the industry relies heavily on Samsung's products, leading to an increase of $22.8 billion in the family's wealth in just one year.

      The shift in Samsung's financial landscape is anchored in a single category: high-bandwidth memory (HBM), which are specialized DRAM chips located in GPU modules used for training and running large AI models. Nvidia’s upcoming B300 server systems require HBM4 chips, and Samsung has successfully entered mass production of HBM4 ahead of its main competitor, SK Hynix, after previously lagging behind. This transition is significant as HBM boasts profit margins that conventional memory chips lack. When Samsung announced its first-quarter results, the semiconductor division was responsible for the majority of the profit increase, transforming what had been a cyclical downturn into the company’s most lucrative quarter in recent years. Nvidia's B300 servers, which can exceed $1 million each, are being distributed to major AI programs and hyperscalers worldwide, with Samsung now a primary supplier of the necessary memory.

      However, the concentration of value in one product line poses both an opportunity and a risk for Samsung. HBM4 represents a significant advancement in memory architecture, evolving from a stacked DRAM design to a logic-integrated base die that allows for greater bandwidth and reduced power consumption. Samsung’s rapid achievement of volume production for HBM4 prior to its competitors offered it a pricing advantage that improved Q1 results. Nevertheless, the AI chip supply chain is notoriously unstable. Factors such as Nvidia's product cycles, the expansion of data centers by major companies like Amazon and Google, and geopolitical restrictions on chip exports to China all affect how much HBM Samsung can sell and at what prices. The stock’s 186% rise in a year reflects expectations for a sustained AI infrastructure boom; a slowdown in this boom could reverse the same leverage that grew the Lee family's wealth.

      This wealth increase comes at a pivotal time for the Lee family's finances. The heirs of the late Samsung chairman Lee Kun-hee, who passed away in October 2020, are currently facing the largest inheritance tax obligation in South Korean history, totaling approximately 12 trillion won, or about $9 billion, to be paid in six annual installments, with the last due in April 2026. The tax was calculated based on the estate's value at the time of Lee Kun-hee's death, when Samsung's stock was significantly lower. The family has financed these payments through dividends, share sales, and loans against their Samsung holdings. The timing of the stock increase has allowed the family to manage the inheritance tax without necessitating a dilutive restructuring of the conglomerate’s cross-shareholding structure, thus maintaining their control over Samsung.

      This control is distinct compared to other global tech companies. Samsung operates as a chaebol, a family-run industrial conglomerate that retains control through intricate cross-shareholdings across various subsidiaries. The Lee family's direct equity stakes in Samsung Electronics are modest, around 5% of outstanding shares, but control is executed through entities like Samsung C&T and Samsung Life Insurance, which hold sufficient voting power to guide the company’s direction. The AI-driven surge in tech stocks has increased the value of all entities within this structure, significantly boosting the family’s wealth beyond what their direct stakes in Samsung Electronics would indicate.

      The wealth transfer to the Lee family has caught the attention of Samsung employees. In March, roughly 30,000 members of the National Samsung Electronics Union protested outside the Hwaseong semiconductor campus, marking the largest labor demonstration in the company's history. The union is advocating for a profit-sharing arrangement that would grant workers a bonus equivalent to 15
