CXMT (Changxin Storage), China's domestic HBM manufacturer, listed on Shanghai Exchange with 472%+ surge and ~$85 billion valuation; $100 billion backlog.
CXMT's debut trading session valued the company at approximately $489 billion based on a restricted share float, placing it far closer in market capitalization to Samsung, SK Hynix, and Micron than in technology, market share, or earnings power. With roughly 7.7% of the global DRAM market, CXMT is already large enough to pressure conventional DRAM pricing. Whether this opening marked a new industry order or merely reflects scarcity-driven demand will depend on progress in high-bandwidth memory, sustained margins, and the company's ability to secure global customers.
CXMT's July 24 listing revealed a tightly controlled float: less than 7% of its enlarged share capital was initially unrestricted, while institutional demand reached approximately 570 times the final offline allocation. The RMB49.50 opening price yielded an implied market capitalization near RMB3.31 trillion—a jump of roughly RMB2.73 trillion before any change in revenue, production capacity, or technology. This represents a valuation of approximately 29 to 33 times annualized 2026 earnings, assuming CXMT repeats its projected first-half profit in the second half of the year.
The company forecasts first-half 2026 revenue between RMB110 billion and RMB120 billion, with attributable profit of RMB50 billion to RMB57 billion. These earnings have been generated during a DRAM shortage characterized by rising contract prices, stronger server demand, and improving product mix—conditions that have lifted profitability across the industry. The current valuation therefore assumes aggressive future performance once memory pricing normalizes.
CXMT represents approximately 11% of global DRAM wafer capacity and targets 15% by 2028, sufficient scale to reduce China's reliance on imported memory and expand domestic supplies. However, factory capacity alone does not ensure comparable profits; manufacturing yield, chip density, and product mix determine how much valuable memory each wafer produces. CXMT faces a significant technology gap: Samsung, SK Hynix, and Micron are already producing or shipping HBM4, while CXMT targets the older HBM3 generation. Closing this gap requires advanced packaging, superior yields, and customer qualification—challenges compounded by export controls that restrict CXMT's access to extreme ultraviolet lithography equipment.
Despite the technology lag, CXMT need not achieve parity to alter the market. Additional DDR and mobile LPDDR supply could weaken conventional-memory pricing, leaving Samsung and Micron more exposed than SK Hynix, whose stronger HBM position provides greater shelter.
Apple's ongoing testing of CXMT DRAM represents a critical near-term milestone. The company is seeking U.S. regulatory permission to use Chinese memory more broadly, though no supply agreement has been confirmed. Apple qualification would demonstrate CXMT's ability to meet the reliability, consistency, and production-volume standards of a major global customer—a validation that carries far greater weight than domestic contracts. Even a limited order could establish CXMT as a credible fourth source, shifting supplier dynamics and strengthening Apple's negotiating leverage with Samsung, SK Hynix, and Micron.
Two catalysts will test whether the valuation can survive improved market conditions. First, CXMT's upcoming earnings report will reveal whether margins withstand weaker DRAM pricing. Second, January 27, 2027 marks the expiry of the six-month lock-up on 70% of the final offline institutional allocation. The price response on that date will reveal how much of the opening premium reflects restricted availability rather than durable underlying demand. Falling DRAM prices, weaker yields, delayed HBM production, or failure to secure global customers could add material pressure to the share price.
CXMT trades on the Shanghai Stock Exchange STAR Market under ticker 688825. The company was not included on the Northbound Stock Connect eligibility list as of July 24, 2026, restricting offshore access to brokerage or institutional routes for mainland A-shares.
