China’s top DRAM maker CXMT plans second Beijing chip plant as semiconductor arms race heats up

ChangXin Memory Technologies, China’s largest domestic DRAM chipmaker, is planning to build a second chip fabrication plant in Beijing and is actively discussing funding to make it happen. The move is part of a broader push to more than double the company’s production capacity by the end of 2027.

CXMT currently operates three 12-inch DRAM fabrication plants spread across Beijing and Hefei. The company plans to add three new factories total, a buildout that would represent one of the most aggressive capacity expansions in the global memory chip market.

Founded in 2016 in Hefei, CXMT has grown from a startup into the world’s fourth-largest DRAM producer. By 2025, the company had captured a 7.67% share of the global DRAM market, a figure that sounds modest until you consider this market has been dominated by three players, Samsung, SK Hynix, and Micron, for decades.

The company’s IPO on the Shanghai STAR Market on July 27, 2026, raised approximately 57.92 billion yuan, roughly $8.6 billion, making it Asia’s largest IPO of the year. Shares surged 466% on debut. Proceeds from that offering are primarily earmarked for memory wafer mass production and R&D initiatives. But building semiconductor fabs is one of the most capital-intensive endeavors in modern industry, which is why CXMT is already seeking additional funding for a new Beijing plant.

The global DRAM market is entering a period of intense competition. Samsung, SK Hynix, and Micron have long operated as a comfortable oligopoly, controlling the vast majority of the world’s memory chip supply. CXMT’s push to nearly double its output by 2027 threatens to disrupt that dynamic.

The risk for CXMT is execution. Building fabs on schedule and ramping yields to competitive levels is extraordinarily difficult. The company also faces the ever-present threat of escalating US sanctions that could restrict access to critical manufacturing equipment, much of which comes from Dutch firm ASML and Japanese suppliers.
