CXMT entered the Roundhill Memory ETF’s top 10 holdings after its Shanghai listing, while HP, Asus and Acer have also begun limited use of the Chinese DRAM maker’s chips in select laptop models.
Roundhill Memory ETF (DRAM) added ChangXin Memory Technologies, or CXMT, in its latest rebalance after the Chinese DRAM maker’s July 27, 2026 Shanghai IPO made it eligible for inclusion. The company entered the fund’s top 10 holdings with a 2.52% weight, ranking eighth, while GigaDevice’s weighting was cut to 1.51% from 2.91%, leaving it in 10th place. CXMT is now the ETF’s highest-weighted Chinese memory holding. The company’s growing profile is also beginning to show up in end products. HP, Asus and Acer have started using small volumes of CXMT DRAM chips in laptops after completing validation in mid-2026, according to Nikkei Asia. The use remains limited to a few models sold outside the U.S. market, as PC makers respond to a memory shortage tied to strong AI infrastructure demand while managing supply constraints, geopolitical sensitivities and long-standing relationships with Micron, Samsung Electronics and SK hynix. Roundhill Memory ETF, listed on the Cboe BZX exchange on April 2, 2026, is described as the world’s first ETF focused exclusively on memory chips, and its assets surpassed $25 billion within three months of launch. CXMT listed on Shanghai’s STAR Market on July 27 at 8.66 yuan per share and closed its first trading day at 49 yuan, a gain of 465.82%. By Aug. 3, the stock closed at 54.99 yuan, giving it a market capitalization of about 3.68 trillion yuan. Omdia data cited in the report said CXMT’s global DRAM market share was about 7.67% in the fourth quarter of 2025, ranking fourth worldwide. The update came as memory-chip shares pulled back globally, with South Korea’s Kospi down 5.12% on Aug. 3 and Samsung Electronics and SK hynix each falling nearly 9%. Morgan Stanley said recent deleveraging may create a new entry point for AI and industrial-cycle investors.
