China’s Chip Boom: CXMT Shares Skyrocket 470% on Debut

Sun Sep 06 2026 13:51:01 GMT+0000 (Coordinated Universal Time)

The first day of trading for China’s largest memory chip maker soars, turning it into the country’s biggest listed company.

ChangXin Memory Technologies (CXMT) exploded onto the Shanghai Star Market, climbing more than 470% in its opening, with its market value topping 3.3 trillion yuan ($487 billion). The surge shows massive demand for AI‑powered chips, even as global tech stocks tumble. China’s focus on domestic chip production and a limited 7% share float helped drive the buying frenzy. Analysts see this as a success marker for the local tech industry's push toward self‑reliance.

Last week, ChangXin Memory Technologies (CXMT) made its debut on Shanghai’s Star Market and shot up over 470% on day one.

The jump pushed CXMT’s valuation to about 3.3 trillion yuan ($487 billion), making it the most valuable company on mainland China’s stock exchange.

Despite a global sell‑off in tech stocks, investors rushed to CXMT because the company specializes in DRAM chips that power AI data centres, smartphones, and PCs.

Only 7% of the shares were available for trading, so demand far outpaced supply, according to investment director Anna Macdonald.

CXMT’s founder, Zhu Yiming, plans to use the IPO proceeds mainly for expanding production and research, helping China meet its goal of tech self‑reliance.

Industry giants Samsung, SK Hynix and Micron still dominate the global DRAM market, producing 90% of all chips. CXMT’s breakout gives Chinese investors confidence in a homegrown alternative.

The launch comes at a time when foreign firms are also booming: earlier this month, SK Hynix raised $26.5 billion in a New York share offering, the largest foreign listing in the US.
