ChangXin Memory Technologies (CXMT) cleared the Shanghai Stock Exchange's STAR Market listing review committee on May 27, the decisive regulatory hurdle for an IPO targeting roughly 29.5 billion yuan (~$4.3 billion). It is on track to be mainland China's largest public offering since CNOOC's $5.1 billion raise in 2022, and — should over-allotment options be exercised, pushing proceeds past $5 billion — the biggest in Asia since CATL's $5.3 billion share sale in May 2025.
The deal
CXMT will offer no less than 10% of its shares on the STAR Market, Shanghai's Nasdaq-style board for strategic tech firms. Reports point to a potential valuation exceeding 2 trillion yuan, a level that would rank it among China's most valuable listed companies. The application, filed in late 2025, stalled in early April when financial documents expired, then resumed on May 1 before clearing committee review.
Founded in 2016 and headquartered in Hefei, CXMT is widely regarded as the only domestic Chinese DRAM maker to have reached volume mass production. By the end of 2025 it held a 7.67% share of the global DRAM market — fourth worldwide, behind Samsung, SK Hynix, and Micron, and first among Chinese producers.
Why it matters for AI infrastructure
Memory, not just logic, is the binding constraint on the current buildout. HBM is sold out, DRAM contract prices have surged, and every AI accelerator rack consumes large volumes of high-bandwidth and standard memory. CXMT's proceeds are earmarked for expanding wafer capacity, upgrading DRAM technology lines, and R&D — with plans to scale DDR4 and LPDDR5 and to develop HBM, the memory tier that feeds GPU compute.
That positions the listing as a state-aligned bid to reduce China's dependence on the three foreign incumbents that dominate memory, under tightening U.S. export controls. For now this is domestic substitution, not frontier competition: CXMT trails on leading-edge HBM and process nodes. But a well-capitalized fourth supplier reshapes the long-run supply picture for buyers already squeezed by the memory crunch.
The financials and the risk
CXMT posted first-quarter 2026 revenue of 50.8 billion yuan, reportedly up 719% year over year, with net profit of 33 billion yuan — a swing fueled by the memory upcycle. The balance sheet is heavier: total debt of about 118.8 billion yuan and accumulated losses near 36.6 billion yuan reflect years of capital-intensive ramp-up.
For enterprise buyers and infra teams, the signal is structural. A capacity-expanding Chinese DRAM champion adds supply optionality over a multi-year horizon, while the eye-watering valuation and debt load are a reminder that the memory supercycle is now minting balance-sheet bets as large as the compute ones.
