South Korean billionaire's risky bet pays off, as SK Hynix debuts in New York

New Delhi, India Jul 10, 2026 ALN: When South Korean billionaire Chey Tae-won rang the Nasdaq's opening bell for SK Hynix's $26.5 billion listing on Friday, it marked the ultimate payoff of a bet many once considered risky: buying a loss-making chipmaker that has since become an AI powerhouse. This moment not only signifies a financial milestone for SK Hynix but also highlights the broader implications of technological advancements in the semiconductor industry, particularly in the context of artificial intelligence (AI) and the growing demand for high-performance computing.

SK Group's 2012 acquisition of Hynix was viewed as problematic even within the business conglomerate. At that time, memory chips were recognized for their cyclical nature and capital-intensive production processes. Hynix was struggling financially, trailing behind its primary competitor, Samsung Electronics, in both market share and technological advancements. This acquisition raised eyebrows and skepticism, as many questioned whether SK Group could turn around a company that was not only losing money but also competing in a highly volatile market.

However, under Chey’s leadership, SK Hynix embarked on a transformative journey. Seeking an edge over Samsung, the company invested heavily in high-bandwidth memory (HBM) chips—a technology that was relatively niche at the time. This strategic decision proved to be prescient as the demand for HBM surged, driven largely by advancements in AI, machine learning, and data processing. HBM chips became a critical component in Nvidia's AI accelerators, allowing SK Hynix to emerge as the world's biggest producer of these essential chips. The success of this technology has not only solidified SK Hynix's position in the semiconductor market but also contributed significantly to the evolution of AI technologies globally.

During an interview with CNBC on the day of the Nasdaq listing, Chey expressed his excitement and pride in the company's achievements. "This is a truly historical moment. We've been waiting for a long, long time. It is a kind of dream and now it is a dream come true," he said. His comments reflect not only personal satisfaction but also the broader narrative of resilience and strategic foresight that has characterized SK Hynix's journey.

Nvidia CEO Jensen Huang, who has praised SK Hynix as a vital partner in the AI industry, emphasized the importance of their collaboration. "SK is our largest memory partner. Without SK's partnership, today's AI industry would not have developed as wonderfully as it has," he stated during a press event in Seoul. This acknowledgment from a leading figure in the tech industry underscores the critical role that memory technology plays in enabling AI advancements.

Kim Dae-il, a former SK Hynix board member and professor at Seoul National University, highlighted the internal dynamics that contributed to SK Hynix's success. Chey made a conscious decision to promote executives from within Hynix rather than importing managers from the broader SK Group. This approach fostered a culture of innovation and commitment among the company’s leadership. He credited Park Sung-wook, a longtime chip engineer appointed as CEO in 2013, for his unwavering belief in HBM technology, even amidst skepticism from other board members. Kim stated, "There was enormous investment behind SK Hynix's rise to that position. Ultimately, Chairman Chey's achievement was making the right bets and putting the right people in place." This internal cohesion and vision have been instrumental in navigating the complexities of the semiconductor market and achieving remarkable growth.

Despite the positive trajectory of SK Hynix, Chey is not without his challenges. As the company rides the AI boom, concerns are mounting regarding whether demand will continue to keep pace with soaring memory prices. In a speech earlier this year, Chey acknowledged the duality of the current situation, stating, "We are facing a shortage of memory supply, which in some ways is a welcome problem for me. People may say, 'Isn't it good because you're making a lot of money?' But this situation cannot last forever." His caution reflects a deep understanding of the cyclical nature of the semiconductor industry, where periods of high demand can be followed by significant downturns.

In response to the burgeoning demand for chips, both SK Hynix and Samsung have pledged to invest hundreds of billions of dollars in new South Korean chip plants. This commitment comes in the wake of President Lee Jae Myung's call for measures to address regional disparities. However, these expansion plans also raise valid concerns about potential oversupply in a market that is notoriously cyclical. The balance between meeting current demand and avoiding future oversupply will be a critical challenge for both companies as they navigate their growth strategies.

Chey, as chairman of SK Group—a sprawling conglomerate with business interests ranging from telecommunications to refining and construction—holds a significant position in the South Korean corporate landscape. While he is not a direct shareholder of SK Hynix, he is the largest shareholder of SK Inc., which holds a 32% stake in SK Hynix's top shareholder, SK Square. His estimated wealth stands at $5.4 billion, as reported by Forbes, reflecting his influence and success in the business world.

Chey’s prominence is further accentuated by his distinct leadership style, which contrasts with many South Korean tycoons who typically prefer to remain out of the public eye. His career has been marked by both triumphs and controversies, including personal setbacks that have drawn public attention. In 2015, Chey publicly acknowledged his estrangement from his then-wife and his relationship with another woman, a candid admission that sparked debate in a society where such matters are often stigmatized. He is currently embroiled in an acrimonious divorce settlement lawsuit, with substantial financial implications that could influence the ownership structure of South Korea's second-largest conglomerate after Samsung Group.

Chey’s past is also shadowed by legal issues; he spent more than two years in prison for embezzling corporate funds before receiving a presidential pardon in 2015. The government’s decision to pardon him was framed as a move to allow business leaders to contribute to the economy’s development. This complicated history adds layers to his legacy, which is increasingly being defined by SK Hynix's remarkable turnaround and its pivotal role in the AI revolution.

As SK Hynix continues to grow and adapt in a rapidly changing technological landscape, the implications of its success extend beyond the company itself. The semiconductor industry is at the forefront of the global economy, driving innovations that impact various sectors, from consumer electronics to automotive technologies. The developments at SK Hynix serve as a case study in strategic investment, resilience, and the importance of technological foresight in navigating the complexities of modern business.
