Little known outside its native China, ChangXing Memory Technologies (CXMT) has to date been selling DRAM to less prominent memory-stick brands. But its memory chips have appeared recently on a DDR5 DIMM stick from Corsair, one of the more recognised memory brands in the West, and the company is also reported to be preparing an IPO that could raise up to $5 billion.
CXMT is the fourth-largest DDR memory maker, after Micron, Samsung, and SK Hynix, with a share of the global market estimated at around 8%, mostly selling to Chinese customers.
The company doesn’t produce High Bandwidth Memory (HBM) used in AI accelerators, and thus its strategy remains at least partially unaffected by the current dearth of memory supply in that segment. It now produces DDR5, which although in short supply, may give companies and consumers an alternative supplier from the ‘big three’ companies who have, since 2022, have switched much of their focus to satisfying demand from hyperscalers building out AI infrastructure.
CXMT’s financial position has changed for the better this year, with first-quarter revenue in 2026 reaching 50.8 billion yuan ($7.5 billion), up 719% from the same period a year earlier. Operating profits for Q1 were 35.4 billion yuan ($5 billion) with a 70% profit margin, compared to a 2.8 billion yuan ($390 million) loss in Q1 2025.
CXMT is expected to use IPO proceeds to expand its facilities, and monthly wafer production is set to rise from the 100,000 wafers it produced in early 2024 to 300,000 wafers by the end of this year. The company is also said to be considering investing in production lines for AI GPUs, a facility that could allow it to enter the HBM market, although no dates have been set at this time.
The company, along with YMTC (another Chinese memory manufacturer) has been removed from the US Pentagon’s list of ‘restricted suppliers’, meaning they can both sell into the lucrative Western market, including bidding for US government contracts.
Memory analyst at Objective Analysis, Jim Handy, said CXMT sold DDR4, as of 2023, at lower prices than those of the top three world memory manufacturers, suggesting that a strategy of undercutting the opposition on price may continue with the latest generation of its DDR5 memory. In the last two years, prices for DDR4 have fallen significantly (after a brief spell when DDR4 cost more than DDR5), and the main producers have stopped production of this last-generation DRAM altogether. Similarly CXMT has transitioned its plants from DDR4 to DDR5.
“Now the majors are making 80% – give or take – gross margins on DRAM. Even a company whose cost to manufacture was twice that of its competition would make a 60% gross margin in this case, so the market is greatly favoring CXMT – for the time being,” Handy said.
The potential for lower RAM prices at the point of sale, therefore, may be limited if CXMT pursues the HBM market hard, and if the commodity market that exists for DRAM takes a downturn. There is a risk that shortage and glut cycles, caused by changes in supply and demand, may sabotage the company’s plans.
“Today’s AI-driven shortage will reverse at some point. When it does, the majors will see prices drop to cost. If CXMT’s costs remain higher than everyone else’s, the company will haemorrhage money during that period,” Handy said.
The short term possibilities for CXMT are therefore contingent on its competitors keeping their eyes on the lucrative AI market for High Bandwidth Memory, and that demand for HBM continues into the medium to long term. The commitment in terms of R&D and manufacturing plant investment mean that DRAM manufacturers operate at a slower speed than global markets react, with many months or even years involved in changing product types. CXMT has an opportunity to embed itself into the DDR5 market and work on lowering its costs while the current focus remains on AI.
