CXMT signs $7B ByteDance deal ahead of Shanghai IPO

ChangXin Memory Technologies, China's largest DRAM manufacturer, has signed a five-year supply agreement with ByteDance worth more than $7 billion, according to a Reuters investigation published Thursday. The deal cements CXMT's transformation from a low-cost alternative into a supplier capable of dictating terms to some of China's largest technology companies.guru3d+1

From Underdog to Price Setter

The ByteDance agreement follows a separate multi-year deal with Tencent valued at more than $3 billion, first reported by Reuters in late June. Neither CXMT, ByteDance, nor Tencent confirmed the contract details.reuters+1

The most striking shift concerns pricing. CXMT was long viewed as a cheaper substitute for Samsung, SK Hynix, and Micron ↘ 2.22%, but Reuters reports that CXMT recently charged more than Samsung's approximately $1,240 price for a comparable 64GB DDR5 server memory module. Several Chinese electronics companies have reportedly complained to regulators that higher memory prices are delaying product introductions.guru3d

CXMT has emerged as the world's fourth-largest DRAM chipmaker with a 7.7% global market share. First-quarter 2026 revenue reached 50.8 billion yuan ($7.5 billion), a 719% year-over-year increase, while net profit hit approximately 25 billion yuan compared with a net loss of 1.6 billion yuan in the same period a year earlier.reuters+2

IPO and Expansion

The company is set to debut on Shanghai's STAR Market on Monday after raising $8.6 billion in what would be Asia's largest IPO this year. CXMT is building factories in Shanghai and Hefei that could more than double its capacity to over 600,000 wafers per month.reuters+1

YMTC, China's top NAND flash maker, is also preparing a listing, with some executives reportedly seeking a valuation of one trillion yuan.guru3d

US Scrutiny Intensifies

The gains come amid shifting regulatory terrain. The Pentagon removed both CXMT and YMTC from its Section 1260H restricted list in early 2025, but YMTC still faces separate Commerce Department export controls. In March, the Federal Acquisition Regulatory Council proposed rules to restrict use of CXMT, YMTC, and SMIC products in government-related commercial goods. As recently as July 16, U.S. lawmakers cited "unacceptable risk" to national security and called for banning Chinese memory chips even from allied supply chains.reddit+3

Both companies remain dependent on deep-ultraviolet lithography because China cannot import advanced EUV systems, and CXMT's high-bandwidth memory technology is reportedly around two generations behind market leaders. New capacity could begin serving international customers during 2027, though strong domestic demand may absorb much of the initial output.guru3d
