CXMT jumps 466% in Shanghai debut to eclipse all other China-listed firms

Chipmaker Changxin Technology Group, known as CXMT, soared nearly 466% in its first day of trading on Shanghai's STAR Market, becoming the most valuable company listed in China with a market capitalization of roughly 3.3 trillion yuan.

CXMT closes at 49 yuan after raising $8.6 billion. The Hefei-based firm raised 57.92 billion yuan ($8.6 billion) through an IPO priced at 8.66 yuan per share, marking Asia's largest this year. Shares ended the session at 49 yuan on Monday, July 27, 2026, surpassing Industrial and Commercial Bank of China's 2.6 trillion yuan valuation.

CXMT holds 7.67% of the worldwide memory chip sector. Based on fourth-quarter 2025 sales data, the company commanded a 7.67% share of the global DRAM market that year, per its IPO prospectus. DRAM chips power devices from smartphones to servers. The sector is led by Samsung Electronics, SK Hynix, and Micron Technology.

The company swings to profit amid AI demand. CXMT recorded an operating profit of 35.43 billion yuan in the first quarter, reversing a 2.83 billion yuan loss from the prior year. This shift reflected rising worldwide computing needs and greater chip allocations from leading producers. The debut follows reports that Apple has started evaluating the firm's DRAM components for handsets sold in China.

Proceeds target memory wafer production and R&D. The company intends to direct most IPO funds toward scaling up memory wafer output and research initiatives to strengthen its technical edge and competitiveness, according to its prospectus. Founded in 2016 by Chairman Zhu Yiming, CXMT held that 7.67% slice of the worldwide memory chip sector in 2025.

Analysts cite limited float and AI self-sufficiency push. Theodore Shou, CEO at Yiyi Capital, told CNBC's "Squawk Box Asia" that such a large gain on debut for a firm of this scale stands out, fueled by a constrained free float and accumulated positive sentiment. Morningstar observed that with artificial intelligence emerging as a matter of national security for China, CXMT stands to gain significantly; local tech giants are expected to accelerate uptake of its products as authorities advance semiconductor independence goals. Shou expressed confidence that the firm will mature into a worldwide leader, while cautioning that enthusiasm around the memory cycle may be approaching a near-term high and that elevated margins will moderate over time.
