7/27/2026, 9:34:25 PM
Record-Breaking Debut on the STAR Market
On July 27, ChangXin Memory Technologies (CXMT) began trading on the Shanghai Stock Exchange’s Science and Technology Innovation Board (STAR market). Within hours the stock price had risen more than fourfold, with the share price reaching roughly 49.5 yuan—well above the IPO price of 8.66 yuan. The surge lifted CXMT’s market capitalization to the range of 3.3 trillion to 3.5 trillion yuan, briefly making it the most valuable listed company on the Chinese mainland. The offering raised between 57.9 billion and 66.6 billion yuan (approximately $8.6 billion to $9.8 billion), marking the largest mainland IPO in recent years.
Background & Context: AI-Driven Demand and Export Controls
CXMT, founded in 2016 in Hefei, Anhui, is a leading producer of DRAM memory chips used in AI servers, smartphones and PCs. A surge in artificial-intelligence applications has created a global shortage of high-bandwidth memory (HBM), driving up prices and boosting demand for DRAM. At the same time, U.S. export restrictions have limited China’s access to the most advanced chip-making equipment, prompting Beijing to prioritize domestic semiconductor capacity. CXMT’s IPO is therefore seen as a cornerstone of China’s push for self-sufficiency in critical AI hardware.

Conflicting Reports & Gaps
- Market capitalization: Sources differ, reporting either 3.3 trillion yuan or 3.5 trillion yuan.

What’s Next
Counterpoint Research forecasts CXMT’s global DRAM share to rise to about 11 % by 2028, but stresses that achieving at least 15 % will be essential for the company to remain competitive. Ongoing U.S. export restrictions on advanced lithography equipment remain a key obstacle to scaling production capacity.
