On September 28, US memory chip stocks fell broadly in pre-market trading, with SK Hynix and SanDisk each dropping more than 3.6%.

Micron Technology declined 2.25%, Western Digital fell 2.8%, Intel dropped over 3%, AMD slid 2.57%, and Seagate Technology lost 2.54%.

On the news front, earlier reports indicated that Solidigm, the US subsidiary of SK Hynix, may pursue a US listing, sparking market concerns over SK Group's complex equity structure.

US media cited people familiar with the matter over the weekend reporting that Solidigm is considering an IPO in the US as early as next year, at which point the data storage product manufacturer could be valued at up to $100 billion.

Affected by this news, SK Hynix shares fell 5% during Monday's Asian session, marking the largest drop in two weeks. SK Square, the largest shareholder of SK Hynix, saw its shares decline more than 8%, while SK Inc., which controls SK Square, also dropped over 6%.

The Korean Corporate Governance Forum stated that the Solidigm listing would further increase the multi-layered shareholding relationships within SK Group and deepen its pyramid-style ownership structure. The forum had urged SK Hynix in August to abandon the plan.

Other market analysts noted that multiple US economic data releases last week showed improvement, and several Federal Reserve officials intensively signaled a hawkish stance, pushing US Treasury yields higher again, which also weighed on US stock market gains to some extent.

Notably, memory chip giant Micron Technology will release its latest earnings report after US market close this Wednesday, which will serve as an important window for investors to observe the prosperity of the memory chip and AI data center supply chain.

Deutsche Bank analyst Melissa Weathers is bullish on Micron, believing that the DRAM supply-demand gap will further widen in 2027 and 2028, with the market potentially reaching supply-demand balance in 2029 and shifting to oversupply in 2030. DRAM demand is expected to grow at a compound annual growth rate of approximately 21% through 2030, compared to a historical average of only around 15%.

The analyst mentioned that DRAM wafer supply compound annual growth rate has been revised up to above 15%, higher than the previous forecast of above 12%, but supply growth remains significantly below demand growth.
