CXMT's stock jumped 472 percent on its market debut and held gains of 462 percent by midday in Asia, establishing it as the most valuable company on a mainland Chinese exchange with a market value near 3.3 trillion yuan (about €415 billion). Its capitalization still trails those of South Korean and US memory chip leaders Samsung Electronics, SK Hynix and Micron Technology.

CXMT ranks among chip firms that have gained substantially from the artificial intelligence surge. The company has also thrived amid China's drive for technological self-reliance despite limits on advanced equipment from US-led export rules.

The firm secured at least $8.6 billion (roughly €7.3 billion) through the offering priced at 8.66 yuan (around €1.10) per share on the Shanghai Stock Exchange's STAR Market, modeled after Nasdaq.

This marked mainland China's second-largest IPO after Agricultural Bank of China's 2010 dual listing in Shanghai and Hong Kong that raised $22.1 billion (about €18.8 billion).

Established in 2016 in Hefei, CXMT stands as one of the globe's top producers of DRAM chips, semiconductors essential for AI servers, vehicles and consumer devices such as smartphones and PCs.

“CXMT holds a vital position in China's AI efforts, especially amid US export controls,” noted Kyle Chan of the Brookings Institution. Restrictions have also prevented China from importing advanced HBM chips, a DRAM variant.

Revenue climbed to 50.8 billion yuan (approximately €6.4 billion) in the first quarter of 2026, rising over 700 percent from the prior year on strong AI-driven demand.

Widespread AI adoption has created a worldwide memory chip shortfall, pushing up costs for some computers and phones. Chan highlighted whether CXMT might ease the broader shortage.

CXMT represents China's strongest prospect for developing advanced HBM chips for domestic AI systems, though it confronts hurdles like supply constraints from restricted access to top tools and reliance on local suppliers.

Counterpoint Research ranks CXMT as the fourth-largest DRAM maker by 2025 shipments with about 8 percent global share, behind Samsung at 36 percent, SK Hynix at 29 percent and Micron at 24 percent.

In early 2026 CXMT held roughly 9 percent of global shipments, with forecasts pointing to 11 percent by 2028. The firm estimates a minimum 15 percent share is needed for long-term competitiveness.

“Tool trade limits remain the main obstacle for CXMT,” stated MS Hwang of Counterpoint. Some US lawmakers have urged blocking American purchases of CXMT chips over security issues.

CXMT and other Chinese firms carry Pentagon designations for alleged military ties, which Beijing has largely dismissed.

CXMT's IPO followed SK Hynix's $26.5 billion (about €22.5 billion) Nasdaq listing earlier this month.
