AI Bubble Fears Surge: Hyperscalers' $285B Debt Load and Semiconductor Valuation Risk

SK Hynix, South Korea's leading memory chipmaker, is adding KRW 21.6 trillion ($15.1 billion) in new investment to the Yongin semiconductor cluster, raising total committed capital to KRW 31 trillion including an earlier KRW 9.4 trillion. The investment runs from March 2026 through December 2030, targeting long-term production capacity expansion for AI memory semiconductors (HBM) amid surging demand. Designed at a total scale of KRW 600 trillion, the Yongin cluster will serve as a core AI memory hub integrating fabs, materials, components, and equipment supply chains. The first fab broke ground in February 2025 and is slated for completion by May 2027. (Source: Yonhap News)
