On September 28, Roundhill Memory ETF fell 5.01% in regular trading, trading at $58.81/share, with turnover of $7.05 billion. The broad-based decline was triggered by reports that SK Hynix subsidiary Solidigm is considering a US IPO as early as next year, with a valuation of up to $150 billion and plans to raise approximately $15 billion.

According to reports, Solidigm has already held underwriter pitch meetings with multiple investment banks this week. The market is concerned that the IPO would deepen SK Group's pyramid-like equity structure while diluting existing SK Hynix shareholders' claims on NAND flash assets, effectively diverting profits to outside shareholders. SK Hynix, which acquired Intel's flash memory business and rebranded it as Solidigm in 2021, saw its Korean-listed shares fall over 5% and its US-listed shares drop more than 3.5%. SanDisk fell over 3.6%, Western Digital declined 2.8%, and Micron dropped more than 2%, putting broad pressure across the memory chip sector.

Separately, Samsung Electronics and SK Hynix are accelerating factory construction timelines, with Samsung advancing its P5 facility schedule and SK Hynix beginning construction of a memory semiconductor plant in Japan, signaling an intensifying capacity race that may further weigh on near-term investor sentiment.
