CXMT and YMTC Near Landmark IPOs Fueled by AI-Driven Memory Demand
Two of China’s leading memory chipmakers are moving closer to public listings that will give them fresh capital to accelerate their pursuit of South Korean giants Samsung Electronics and SK Hynix, the South China Morning Post reports. ChangXin Memory Technologies (CXMT), China’s leading dynamic random-access memory (DRAM) producer, won approval last week for its nearly 30-billion-yuan (US$4.4 billion) initial public offering on Shanghai’s STAR Market, a deal that could become the largest on that exchange since SMIC’s blockbuster debut in 2020. Meanwhile, NAND flash champion Yangtze Memory Technologies Corp (YMTC) has begun IPO preparations and could formally submit a listing application as early as this month, with proceeds directed at equipment and research and development.
The twin listing efforts come as both companies benefit from a global memory upcycle driven by artificial intelligence demand. More importantly, analysts say they reflect a broader shift in China’s semiconductor industry, where memory makers are evolving from technology catch-up players into increasingly credible competitors in global markets.
CXMT’s 719% Revenue Surge and YMTC’s Rising Global Market Share
South China Morning Post notes that the financial results underpinning CXMT’s IPO are striking. The company, based in Hefei, reported first-quarter revenue of 50.8 billion yuan, up 719 percent from a year earlier, while net profit reached 33 billion yuan, reversing a loss in the same period last year, according to figures disclosed in its IPO prospectus. The offering is expected to value the company at more than 2 trillion yuan. The IPO approval was “very significant,” said Ray Wang, a Seoul-based semiconductor analyst at SemiAnalysis. “It is one incremental proof that Chinese memory companies are increasingly mature and structurally competitive against their US and Korean peers, although technology-wise they are still a few years behind.”
The market share data confirms the trend. YMTC’s global NAND flash market share rose from 8 percent in the first quarter of 2025 to 11 percent by the fourth quarter, according to data from research firm Counterpoint, making it one of the fastest-growing NAND suppliers globally. By comparison, Samsung remained the market leader with a 27 percent share, followed by SK Hynix at 22 percent. HSBC Qianhai Securities estimated that YMTC’s global shipment share rose from more than 10 percent in the first quarter of 2025 to 13 percent by the third quarter, approaching Micron Technology’s 14 percent share. Once YMTC’s new Wuhan production line begins operating in the second half of this year, the brokerage said, it could overtake rivals to become the world’s third-largest NAND producer.
CXMT’s DRAM progress is similarly notable, if more modest. The company accounted for 5 percent of the global DRAM market in the fourth quarter of 2025, up from 4 percent a year earlier, according to Counterpoint data, still far behind Samsung’s 36 percent share and SK Hynix’s 32 percent, but a meaningful gain in a market that has historically been impenetrable for new entrants.
Still Years Behind in HBM, but Disruptive in Mature Memory Segments
Despite such progress, analysts say the immediate threat to Korean companies remains limited. YMTC is roughly two years behind global leaders in NAND flash technology, while CXMT remains around three years behind in commodity DRAM and approximately four years behind in high-bandwidth memory (HBM), the advanced memory technology used in AI servers, according to Wang’s estimates. HSBC analysts led by Steven Sun described China’s emerging memory champions as a “real but asymmetric threat” in a May report, arguing that they are likely to be more disruptive in mature memory segments than in cutting-edge AI memory products over the next three years.
That asymmetry is strategically important. Samsung and SK Hynix have largely moved away from older-generation memory segments to prioritize HBM and higher-margin products, leaving room for CXMT to gain share in consumer markets such as smartphones, PCs, and automotive applications. “The biggest concern for Korean companies is always capacity, followed by market share,” Wang said. “Materially bigger capacity with improved shipments could impact future memory supply and demand, which in turn would hit memory pricing.” He added: “Chinese memory makers might gain incremental share in the Chinese market first. CXMT can gain share in consumer segments in China, not only for domestic brands but even foreign brands sold in China.”
Memory Chips as Strategic AI Infrastructure
The competitive dynamics are further complicated by the geopolitical context. YMTC was placed on the US Entity List in 2022, severely restricting its access to American technology. Yet the company has continued to advance its 3D NAND technology, a testament to the depth of engineering talent and the scale of resources available within China’s semiconductor ecosystem. CXMT, which has not been placed on the Entity List, has been able to access a broader range of equipment and materials, enabling it to achieve a somewhat faster development trajectory.
The implications for the US-China AI and tech race are significant. Memory chips are a foundational component of AI infrastructure. The massive datasets and complex algorithms that power advanced AI models demand high-performance, high-capacity memory solutions. As China seeks to build a world-class AI ecosystem, ensuring a secure and reliable supply of domestic memory chips is a strategic imperative. The IPO capital raised by CXMT and YMTC will directly fund the next generation of Chinese AI infrastructure, reducing dependence on foreign suppliers and strengthening the domestic technology stack.
