CXMT Chairman Zhu Yiming Amasses $15.9 Billion Fortune By Growing Memory Chip Maker Into Micron Rival

Zhu Yiming, the chairman of Chinese memory chip giant CXMT, has added more than $12 billion to his fortune following the company’s blockbuster listing in Shanghai on Monday. Shares jumped over 500%, as investors clamored for a piece of a firm that has risen from obscurity to compete with rivals such as Samsung and Micron at home amid an AI-induced demand boom.

The 54-year-old chairman owns a small stake in the company, which is now China’s largest onshore-listed firm. Zhu, who studied in the U.S. and is a permanent resident of Singapore, also has shares in GigaDevice, a fellow Shanghai-listed chip maker he founded in 2004. Combined, the mogul’s total net worth is $15.9 billion.

Now sporting a market capitalization of 3.7 trillion yuan ($546.4 billion), CXMT’s whopping rally was expected, says Shen Meng, Beijing-based managing director of boutique investment bank Chanson&Co. Investor enthusiasm reached fevered heights as the company is seen as a point of national pride at the forefront of an intensifying technology rivalry with the U.S. “Local demands will continue to benefit CXMT’s future development,” he says.

The chipmaker didn’t respond to requests for comment. In what is Asia’s largest initial public offering so far this year, and before an over-allotment option, the Hefei, Anhui-based company raised 57.9 billion yuan ($8.6 billion) in July by selling about 6.7 billion shares at 8.7 yuan each. CXMT intends to use the proceeds for production expansion as well as research and development, according to its prospectus.

China is nurturing such domestic champions to control its own technology supply chain. Founded in 2016, CXMT counts the China Integrated Circuit Industry Investment Fund (also known as the Big Fund), the Hefei municipal government and Alibaba’s cloud computing unit among its largest shareholders. Amid heavy R&D spending, the company burned through billions of dollars and suffered steep losses. It only turned its first profit last year, as demand from AI-related sectors boosted sales of memory chips.

The product, widely used in electronic devices such as laptops and smartphones, also stores the data that AI models need. Amid the global buildout of AI infrastructure like data centers, demand has far outstripped supply, triggering a shortage that SK Hynix CEO Kwak Noh-Jung expects to persist beyond 2030. The South Korean giant had its own blockbuster listing in July, raising a record-breaking $26.5 billion in the U.S.

For its part, CXMT counts Chinese internet giants including Alibaba, ByteDance and Tencent among customers, according to the prospectus. It also sells to device makers from Lenovo to Xiaomi. Last year, the firm reported a net profit of 1.9 billion yuan on revenues of 61.8 billion yuan, its prospectus shows. Over 97% of sales came from the Greater China region, according to research firm Morningstar.

For the first half of this year, sales are expected to jump as much as 677.3% year-on-year to 120 billion yuan, while net profit will soar by up to 2,544.2% to reach 57 billion yuan from the same period a year ago, the company projected in its prospectus. CXMT, which reportedly has drawn Apple’s interest, has risen to become the world’s fourth largest memory chip maker by market share, according to Counterpoint Research. In the first quarter of 2026, the company had 8% of the global market, behind Micron’s 22%, SK Hynix’s 29% and Samsung’s 38%.

Yet Neil Shah, vice president of research at Counterpoint Research, cautions that “a generational technical gap” still exists between CXMT and its global “Big Three” rivals when it comes to more advanced high bandwidth memory (HBM) chips. Zhu, however, seems intent on closing it.

The mogul studied electronic engineering at the State University of New York at Stony Brook, after receiving a master’s and bachelor’s degree in physics from China’s Tsinghua University. He then got jobs in Silicon Valley, working as an engineer and then project manager for iPolicy Networks and Monolithic System Technologies, respectively.

But Zhu soon wanted to return to China, as he believed the opportunities back home were far greater, according to a post from Tsinghua Alumni Association. The key reason, according to the Tsinghua post, is that China then relied on imports for over 90% of its memory chips.

The billionaire’s first company was GigaDevice, which makes flash memory chips. He was later tapped to run CXMT, with support from the Hefei municipal government.

Located in China’s Yangtze Delta region that underpins much of the country’s economic growth, the city might not be as well-known as Beijing or Shanghai. But it is “one of the great examples” of the country’s so-called patient capital, which has a greater tolerance for losses, according to a June report from SemiAnalysis. The California-based research firm points to Hefei’s bailout of once struggling electric vehicle maker Nio and support for display maker BOE Technology Group as examples.

The funding gave Zhu the financial firepower to expand. According to the SemiAnalysis report, CXMT purchased a large number of patents from Qimonda, a German chip maker that collapsed amid the 2008 global financial crisis. It also hired engineers from around the world, tapping their know-how to build CXMT.

Today, the company has room for further growth, thanks largely to the AI spending cycle, according to SemiAnalysis. The research firm projects that CXMT will generate over $50 billion in sales this year. But Morningstar analyst Jing Jie Yu cautions in a July report that the Chinese company might not attract many customers abroad, with demand still coming mostly from home markets.

“We do not expect the company to capture a material share of the global AI memory market due to technological gaps versus global leaders, which stem from restricted access to chipmaking equipment and geopolitical tensions which limit international adoption,” the analyst wrote.
