SK Hynix hits $1 trillion market cap on AI memory boom - qz.com

SK Hynix's stock surged past the $1 trillion market cap milestone, driven by robust demand for high-performance memory chips in AI data centers. As a leading supplier of high-bandwidth memory (HBM), S... Read original →

SK Hynix’s $1 trillion valuation signals a structural shift in memory demand, driven by AI infrastructure rather than cyclical swings. Technologically, HBM3E and upcoming HBM4 will accelerate adoption of 3nm nodes and EUV lithography in DRAM, pressuring ASML to prioritize High-NA EUV shipments and redirecting advanced packaging capacity—like TSV and CoWoS—toward South Korea. On the compliance front, U.S. export controls are forcing SK Hynix to reconfigure its Xi’an packaging operations, raising near-term costs but enhancing its strategic alignment within the U.S.-ROK tech alliance. Samsung is likely to bundle HBM4 with its own AI accelerators to claw back share, while Micron may leverage CHIPS Act subsidies to fast-track Arizona-based HBM production. Over the next 18 months, persistent HBM supply shortages will sustain pricing power, positioning SK Hynix’s capital efficiency as the new industry benchmark and redefining memory valuations around AI infrastructure integration—not just bit output.
