SK Hynix plans $38 billion memory fab expansion as AI demand drives semiconductor investment race
South Korean chipmaker SK Hynix announced Friday it will invest 38 billion dollars in two new memory manufacturing plants in South Korea. One facility in Yongin will focus on high-bandwidth memory and next-generation DRAM chips used in artificial intelligence systems. A second plant in Cheongju will produce NAND flash storage chips. Construction begins in 2027 with production starting between 2028 and 2029. The investment reflects surging demand from tech companies building AI data centers. Analysts emphasize these new factories won't produce significant volume for years, meaning memory shortages and high prices will likely persist through 2028. Micron Technology stock briefly dipped but recovered, as investors noted it has already pre-sold its entire 2026 high-bandwidth memory supply and its own New York fab won't start production until 2030. Wall Street maintains bullish ratings on both SK Hynix and Micron, signaling confidence in sustained AI-driven memory demand.
Key facts
- SK Hynix approved 54 trillion Korean won or $38.1 billion for two new fabrication plants
- Yongin Y2 facility will receive $24 billion and produce HBM and advanced DRAM by 2029
- Cheongju M17 facility will receive $13.6 billion and produce NAND storage chips by late 2028
- Micron has pre-sold its entire 2026 high-bandwidth memory supply to Nvidia, Microsoft, and Alphabet
- New memory supply from industry expansions not expected to meaningfully arrive until late 2027 at earliest
- SK Hynix controls roughly 58-62 percent of the global high-bandwidth memory market
- Wall Street assigns consensus Strong Buy ratings to both SK Hynix and Micron with Micron showing 81 percent upside target
Limits of this briefing
Coverage analyzed reflects primarily technology and financial media; limited perspective from manufacturing workers or supply chain partners. Future cyclicality risks and whether AI demand sustains through 2028-2029 remain uncertain and insufficiently covered.
