CXMT IPO 2026: China's Memory Chip Giant Goes Public

CXMT stands for ChangXin Memory Technologies (长鑫存储), a Chinese state-backed DRAM chipmaker headquartered in Hefei, Anhui. Founded in 2016, it is China's main effort to develop domestic memory chips and reduce dependence on Samsung (South Korea), SK Hynix (South Korea), and Micron (US).

CXMT listed on Shanghai's STAR Market on July 27, 2026, in Asia's largest IPO of 2026. The company raised approximately $8.6 billion. Sources: CNBC, Bloomberg.

CXMT shares surged approximately 471% on their first trading day (July 27, 2026), an exceptional gain even by STAR Market standards. Sources: TrendForce, Bloomberg.

After the first-day surge, CXMT's market capitalisation reached approximately $487 billion, making it China's most valuable listed company and exceeding the market cap of both Intel and Cisco. Note: first-day prices are highly volatile. Sources: TrendForce, CNBC.

The CXMT IPO is the largest in Asia in 2026 and signals that China is building globally competitive memory-chip capacity despite US semiconductor export restrictions. TrendForce described the debut as reshaping global memory dynamics. IPO proceeds are expected to fund further capacity expansion.

Yes. CXMT operates under US export controls that restrict access to advanced chip-making equipment, including EUV lithography tools. Despite these constraints, CXMT has ramped DRAM production using older equipment and domestically developed tools. The scale of the IPO suggests investors believe CXMT can continue growing regardless.

CXMT produces DRAM chips, the type of memory used in smartphones, computers, data centres, and other electronics. It has reported shipping DDR4 and DDR5 products. DRAM is strategically critical: the ability to make it domestically is a core goal of China's semiconductor independence policy.

In market share terms, Samsung holds roughly 43% of the global DRAM market, SK Hynix ~30%, and Micron ~23%; CXMT's share is smaller but growing. In market cap terms post-IPO, CXMT (~$487 billion) exceeds both Intel and Cisco, though market cap and market share are different metrics. Sources: TrendForce.

The STAR Market (Science and Technology Innovation Board, 科创板) is a Nasdaq-style exchange launched by the Shanghai Stock Exchange in 2019 for high-tech and science-focused companies. It has relaxed profitability requirements versus China's main boards, making it the preferred listing venue for chipmakers and deep-tech firms.
