China memory chipmakers gain power amid AI boom, drawing U.S. scrutiny

Key facts

• Chinese chipmaker CXMT has become the world's fourth-largest memory chip producer.
• CXMT is reportedly charging prices higher than South Korean rivals Samsung and SK Hynix due to soaring demand.
• CXMT recently signed a five-year agreement with ByteDance valued at over $7 billion.
• Both CXMT and YMTC are considered key players in China's memory chip sector and are preparing for IPOs.
• The U.S. Pentagon has designated CXMT and YMTC as Chinese military companies.
• YMTC is currently on the U.S. Entity List, limiting its access to U.S. technology.

Chinese memory chip manufacturers ChangXin Memory Technologies (CXMT) and Yangtze Memory Technologies Corp (YMTC) are experiencing a surge in power and influence, driven by the global demand for AI data centers. CXMT has risen to become the world's fourth-largest memory chip maker and is now reportedly dictating prices, even to major clients like Huawei, leading to a confrontation with a Huawei-affiliated equipment vendor, SiCarrier.

The increased demand for memory chips, essential for running applications and storing data, has transformed a previously low-margin business into a critical component for AI infrastructure. This has allowed Chinese companies, which have historically relied on government funding and incurred losses, to gain significant pricing power. In some instances, they are charging more than established South Korean rivals, Samsung and SK Hynix, as Chinese buyers scramble for supply.

CXMT recently secured a five-year agreement with ByteDance, the parent company of TikTok, valued at over $7 billion. Both CXMT and YMTC are preparing for significant IPOs, signaling their growing importance in the global semiconductor market.

However, this newfound clout has also attracted increased scrutiny from the United States. The U.S. Pentagon has designated both CXMT and YMTC as Chinese military companies, alleging their role in China's military-civil fusion strategy, which both firms deny. YMTC is already subject to U.S. export restrictions due to its placement on the Entity List. Discussions are ongoing in Congress regarding further curbs on their access to chipmaking equipment, though the U.S. administration is reportedly divided on the extent of these restrictions. Notably, Apple has argued for CXMT's importance and sought assurances that it would not be blacklisted.
