SK Hynix, South Korea's leading semiconductor company, has seen its market capitalization soar by 700% over the past year, surpassing 100 quadrillion won and overtaking Samsung Electronics as the most valuable asset in Korean conglomerate history. However, the traditional script of chaebol succession is being rewritten as SK Group's third generation, led by Choi Tae-won's children, diverges from expected roles. Choi Yoon-jung, the eldest daughter, is involved in SK Bioscience and leads strategic initiatives, while Choi Min-jung, the second daughter, has pursued a career in AI healthcare and international policy, reflecting the geopolitical nature of the semiconductor industry. Meanwhile, Choi In-geun, the eldest son, has taken a quieter path, joining McKinsey after leaving SK E&S. This shift marks a departure from the conventional chaebol succession model, where the eldest son typically assumes leadership. As SK Hynix becomes a global geopolitical asset, the Choi siblings are tasked with navigating new challenges in the AI era, moving beyond traditional family roles to redefine their legacy in the global market.
