CXMT Corporation
CXMT makes memory chips that store data in phones, computers, and servers.
CXMT is a Chinese memory chip maker, one of the very few companies in the world that can mass-produce DRAM — the cheap, fast working memory that lets your phone juggle a dozen apps and your laptop keep a browser full of tabs open without choking. Almost everyone has heard of the chip designers, but memory is a different game: it is a commodity sold by the gigabyte, priced by the market, and won on manufacturing scale and cost.
For decades this business was essentially a three-company club: Samsung Electronics, SK Hynix, and Micron Technology. CXMT is the upstart trying to crash it. The company was founded in 2016 in Hefei, backed heavily by local and state investment, and it now sells DRAM for phones, PCs, and servers, plus the simpler memory used in cars and household gadgets. Its customers are device makers and module assemblers who buy chips in bulk and care mostly about price, capacity, and whether the supplier can deliver on time. The catch is that memory is a brutally cyclical business. When prices are high, everyone builds factories; when the new factories come online, prices collapse and weaker players bleed. CXMT is also fighting an uphill battle on tools: US export controls have restricted its access to advanced chipmaking equipment, so it has leaned on older machinery and domestic suppliers to keep expanding. It has poured money into new fab capacity, betting that China's huge electronics industry would rather buy memory at home than import all of it.
That bet is as much strategic as commercial. Beijing sees memory chips as a choke point worth paying to escape, so CXMT gets capital and support that a purely private company could not easily raise. The payoff would be a real domestic supplier; the risk is that it ends up in a price war with three giants that have far deeper experience and better tools. For now, CXMT is the most credible Chinese challenger in a market the rest of the world has dominated for years.

BIG PICTURE
CXMT now makes one in every ten dollars the world spends on DRAM memory chips
- 38% Samsung
- 25% SK Hynix
- 24% Micron
- 10% CXMT
- 3% Others
Memory chips are the short-term workspace every phone and computer needs, and in the second quarter of 2026 Chinese newcomer CXMT supplied 10 percent of the global market by revenue. The three companies that long shared almost all of it, Samsung, SK Hynix and Micron, slipped to a combined 87 percent. CXMT's sales are winning customers as it moves from domestic buyers toward global PC and phone makers. Source: Counterpoint Research, reported by China Daily, data from 2026
Timeline
Zhu's Bet on China's DRAM Gap
Zhu Yiming, the founder of chipmaker GigaDevice, looked at two facts that didn't add up: China bought huge amounts of DRAM memory chips, but made almost none of its own. So he struck a deal with the city of Hefei to start CXMT, with a total commitment that would eventually reach 150 billion yuan. It was the start of a long, expensive war of attrition to build a memory chip industry from nothing.
Zhu Goes All In, No Salary
Two years later, Zhu resigned as CEO of GigaDevice to work on CXMT full-time. He promised to take no salary until the company made a profit — a promise he kept for seven years. That kind of vow tells you how long and hard he expected the road to be.
China's First Homegrown DDR4 Chip
In 2019, CXMT mass-produced China's first self-designed, self-made 8-gigabyte DDR4 memory chip. It was a from-zero-to-one breakthrough: the country finally had a working DRAM chip of its own. That mattered because DRAM is the basic memory that every computer and phone needs, and China had been entirely dependent on imports.
Buying Qimonda's Patents
CXMT also bought DRAM patents and technical documents from Qimonda, a defunct German chipmaker. Those papers gave the company a legal and technological foundation — a way to stand on someone else's shoulders instead of starting from a blank sheet. It was a shortcut to legitimacy in a business where patents are a minefield.
The Brutal Downturn and Losses
Then the memory market turned ugly. DRAM prices fell by roughly half from their peak in early 2022, and CXMT lost 16.34 billion yuan in 2023 alone. By the end of 2025, its cumulative losses had reached 36.65 billion yuan — a reminder that this is a business where you can do everything right and still bleed for years.
First Profit as AI Booms
Just when it looked like the losses might never end, everything flipped. Explosive AI demand sent the global DRAM market into a historic super-cycle, and CXMT's three big 12-inch factories came online right in time. The company posted its first full-year profit: revenue of 61.8 billion yuan, up 155.6 percent, with a net profit of 1.875 billion yuan. After seven lean years, the bet finally paid off.
Shanghai IPO Goes Wild
CXMT's stock market debut on the Shanghai STAR Market was a frenzy. Shares surged 465.82 percent on the first day, pushing the company's value above 3 trillion yuan. A single day's trading hit 140 billion yuan — a record for any A-share stock — and for a moment CXMT was mainland China's most valuable listed company.
Breaking the Three-Way Monopoly
By the second quarter of 2026, CXMT held about 7–8 percent of the global DRAM market, ranking fourth worldwide. That may sound small, but it broke the three-way monopoly of Samsung, SK Hynix and Micron that had once seemed unassailable. For the first time, a Chinese company had a real seat at the memory table.
Record Profits, Falling Stock
Then came a strange twist: even as CXMT forecast record net profit of 131–132.5 billion yuan for the first three quarters of 2026, its shares fell to a fresh low, down more than a quarter in a month from their post-IPO highs. Investors were worried that DRAM price growth was slowing and that the AI trade had become too expensive. The lesson: a great business and a great stock are not always the same thing.
