On Tuesday, tech stocks experienced a sharp decline following CXMT's announcement of progress in developing new memory chip architecture that increases data density. This news is particularly concerning for global competitors like Micron, SK Hynix, and Samsung, as CXMT is seen as a rising threat in the memory chip market.
In premarket trading, Micron shares fell by 3.7%, while SK Hynix's shares dropped 10% and Samsung's fell 7.4%. CXMT, which recently made headlines with a 466% surge in its IPO on Shanghai's STAR Market, has since seen a slight decline in its share price but maintains a substantial market cap of 3.46 trillion yuan ($520 billion).
Analysts are closely watching CXMT's ability to close the technological gap with established players, especially in high-bandwidth memory crucial for AI applications. Despite facing challenges due to U.S. export controls on advanced chipmaking equipment, CXMT's market share in the global DRAM sector has increased to approximately 10%, up from 4% a year ago.
This growth, coupled with potential sales to data centers outside the U.S., could indirectly impact Micron and other competitors. Additionally, Apple is reportedly testing CXMT's DRAM chips for its devices sold in China, indicating a potential shift in supplier dynamics.
Overall, CXMT's advancements and market gains could reshape the competitive landscape in the memory chip sector, prompting investors to reassess the market positions of established companies
