While Wall Street is in overdrive on the coming AI mega-listings, SpaceX, Anthropic and OpenAI, something that could shake the leadership of the memory trade is taking shape in China.
Investors chasing the memory rally with Micron Technology Inc.
The first is YMTC, or Yangtze Memory Technologies Co., China's leading maker of NAND flash.
The second is CXMT, or ChangXin Memory Technologies, which is its largest DRAM manufacturer.
Both are state-backed. Both are moving toward public listings to fund their expansion. And both could become a real problem for the AI-driven memory boom.
CXMT Just Cleared China's Biggest Listing In Years
ChangXin Memory cleared the Shanghai Stock Exchange's listing review on May 27 and now waits only on the securities regulator's sign-off.
It plans to raise about 29.5 billion yuan, roughly $4.4 billion, in what would be the largest mainland listing since China Mobile in January 2022.
The financials it disclosed are what surprised the market. Revenue rose 156% to 61.8 billion yuan in 2025, and the company swung to a profit after losing money for years.
The first quarter of 2026 witnessed an even stronger rise. Revenue jumped more than eightfold from a year earlier to 50.8 billion yuan, and net profit attributable to the parent reached nearly 24.8 billion yuan, about $3.5 billion.
A company founded in 2016 with no products is now the world's fourth-largest maker of DRAM.
Its global share roughly doubled to about 8% in the first quarter from around 3% a year before.
Nikkei Asia reported that the company has evolved from what many investors viewed as a government-backed semiconductor project into a commercially successful memory manufacturer generating meaningful profits and expanding market share.
YMTC Is Already Level With Micron On Flash
The flash side of the story is further along than most investors realize.
YMTC's share of the global NAND market has climbed to about 11%, up from roughly 9% a year earlier, by Counterpoint Research's count, closing the gap with Micron and SanDisk.
YMTC cleared the tutoring stage of its own listing on May 19 and is ramping a third plant in Wuhan, with capacity for DRAM and the stacked memory that feeds AI chips coming next.
Why Micron And SanDisk Investors Should Pay Attention
The AI boom has been a windfall for memory producers.
Micron's stock has soared as demand for high-bandwidth memory, or HBM, used in Nvidia's AI accelerators continues to outstrip supply.
Yet the same forces enriching today's market leaders may also be creating tomorrow's competitors.
As Samsung, SK Hynix and Micron allocate capacity toward premium AI memory products, CXMT has aggressively expanded shipments of mainstream DRAM products.
According to estimates from Arisa Liu of Taiwan Industry Economics Services, Chinese parts undercut equivalent global chips by more than 15% which pulls in price-sensitive buyers across the general-purpose server and consumer markets.
MS Hwang, a research analyst at Counterpoint Research, said the Chinese makers are taking share now not by undercutting on price but "because they have the volume that others lack."
Neither CXMT nor YMTC currently threaten the technological leadership of Micron or SK Hynix in advanced HBM memory.
However, the trajectory is becoming difficult to dismiss.
