2. Chey Tae-won - $11.2 Billion

Chey Tae-won, Chairman of SK Group, ranks second with $11.2 billion. SK Group is South Korea's second-largest conglomerate by revenue, with major operations in energy, semiconductors, and battery manufacturing.

Under his guidance, the chipmaker became a global leader in memory semiconductors, particularly high-bandwidth memory (HBM) used in AI data centers. SK Hynix's market capitalization exceeded $120 billion in early 2026, driven by demand from Nvidia and other AI firms. SK Group's total assets are valued at over $300 billion, and its green energy investments, including battery joint ventures with Ford and Volkswagen, have further solidified Chey's position.

He has driven Samsung's push into foldable phones, which now account for 60% of the global foldable market, and expanded semiconductor foundry capacity to challenge TSMC.
