SK Group’s Strategic Shift: AI Leadership and Financial Milestones

As of June 2026, South Korea’s second-largest conglomerate, SK Group, is aggressively positioning itself as a cornerstone of the global artificial intelligence economy. Under the leadership of Chairman Chey Tae-won, the group has integrated its vast resources across semiconductors, energy, and telecommunications to secure a dominant role in AI infrastructure. This transformation includes record-breaking market valuations for its semiconductor arm, SK Hynix, and major international investments in data centers and advanced memory technologies.

How SK Hynix Reached a Historic Market Valuation

SK Hynix, the group’s semiconductor powerhouse, has become a central figure in the global AI hardware race. On May 4, 2026, the company’s market capitalization surged past 1,000 trillion Korean won, a milestone that cemented its status as the second-largest firm on the Korea Composite Stock Price Index, trailing only Samsung Electronics.

Market analysts attribute this rally to the surging demand for High Bandwidth Memory (HBM), a critical component for AI processors. According to reports from May 2026, the company’s stock price hit 1.42 million won during trading sessions, fueled by expectations of expanded capital expenditure from major global technology firms. Financial institutions, including Eugene Investment & Securities, have set ambitious target prices for the stock, citing the company’s role as the world’s leading DRAM manufacturer and a dominant force in the HBM market.

What Is SK Group’s Strategy for AI Infrastructure?

SK Group is not limiting its AI involvement to chips. The company is actively building a vertically integrated AI supply chain. In 2025, the group broke ground on a 5.1 billion USD investment with Amazon to construct a massive AI data center in South Korea, expected to be operational by 2029 with a 100-megawatt capacity.

Chairman Chey Tae-won has been vocal about the long-term challenges facing the tech sector. At the NVIDIA GTC conference in March 2026, he warned that global chip shortages could persist until 2030. To combat this, SK Hynix plans to double its wafer production capacity over the next five years. Furthermore, the group is deepening its collaboration with industry leaders like NVIDIA and Foxconn to ensure its technology remains embedded in the next generation of AI infrastructure.

How the Group’s Legacy Businesses Are Evolving

While AI is the current focus, SK Group’s history reflects a consistent pattern of strategic pivots. Founded in 1953 as Sunkyong Textiles, the firm transitioned through polyester production in the 1960s, a full-scale petroleum integration in the 1970s and 80s, and a major entry into telecommunications in the 1990s.

Today, this diversification continues through:

• Energy Integration: The 2024 merger of SK Innovation and SK E&S created a comprehensive energy entity with assets totaling 100 trillion Korean won.
• Telecommunications: SK Telecom continues to leverage its history of innovation, including the early commercialization of CDMA technology, to advance 6G research.
• Global Expansion: SK maintains a significant footprint in the United States, with operations spanning over 20 states. Recent developments include the expansion of Solidigm’s development in Sacramento and the growth of SK On’s energy storage system (ESS) initiatives.

Future Outlook

The road ahead for SK Group is defined by its ability to scale production to meet the insatiable appetite for AI-ready hardware. With the company’s leadership meeting with NVIDIA’s CEO Jensen Huang in June 2026 to discuss further AI cooperation, the group appears set to maintain its momentum. Investors and industry observers are now looking toward the second half of 2026 to see if the planned production increases and infrastructure projects can keep pace with the evolving demands of the global tech market.
