Following a sharp correction in artificial intelligence (AI)-related stocks, South Korean semiconductor giants Samsung Electronics and SK Hynix rebounded on Tuesday, recovering from significant losses... Read original →

The rebound of SK Hynix and Samsung isn't just sentiment recovery—it reveals acute concentration risk in the AI memory supply chain. NVIDIA’s multi-year HBM4 deal with SK Hynix will accelerate EUV adoption in sub-3nm DRAM, pressuring Micron to close its tech gap and forcing TSMC to reallocate CoWoS capacity. While U.S. rate hikes and Middle East tensions triggered short-term selloffs, the deeper threat lies in potential export controls: any restriction on advanced lithography tools to Korea could derail expansion plans. Over the next 12–24 months, HBM demand from AI servers will grow at >40% CAGR, but the market is consolidating—only three players can mass-produce HBM3E. Technical moats are now translating into pricing power; stock volatility is noise compared to the race for HBM4 yield and cost leadership.
