SK Hynix Rises 13% and Micron Gains 19% to Join TSMC in $1T Club
TSM•SK Hynix surged 13% to exceed $1 trillion in market cap and Micron jumped 19%, marking simultaneous trillion-dollar valuations as AI-driven demand for high-bandwidth memory accelerates. TSMC, which first topped $1 trillion this month, stands to benefit from sustained HBM chip shortages and booming data-center orders.
1. Sector Repricing Drives Trillion-Dollar Valuations
SK Hynix’s 13% surge and Micron’s 19% rally propelled both companies past a $1 trillion market capitalization, following TSMC’s milestone earlier this month as AI development fuels unprecedented demand for memory chips.
2. TSMC’s Lead in Advanced Fabrication
TSMC became the first pure-play memory supplier to cross the $1 trillion threshold, highlighting its dominant position in advanced wafer foundry services and its critical role in supplying high-bandwidth memory to AI accelerator makers.
3. AI-Driven HBM Demand Tightens Supply
Specialized high-bandwidth memory used in data-center servers and AI accelerators has sold out across major producers, underpinning strong pricing and capacity utilization trends that support TSMC’s revenue growth.
