ChangXin Memory Technologies has agreed to supply Tencent with roughly $3bn of memory chips, two people familiar with the matter told Reuters, in a deal that would bind one of China’s largest cloud operators to its largest homegrown DRAM maker.
Neither company has confirmed the agreement publicly, and the figure comes from sourcing rather than a filing or a statement. Reuters reported the arrangement on 29 June, attributing both its existence and its size to people it did not name.
The number should be read with that in mind. What is firmer is the relationship behind it, which is already a matter of record.
CXMT lists Tencent among its end customers, alongside Alibaba, ByteDance, Lenovo, and Xiaomi, though sales often run through distributors rather than directly.
The two have been working together on the unglamorous but decisive task of validation: Tencent has been testing CXMT’s domestically made DDR5 chips for use in its servers, the high-capacity components that feed AI computing. A multibillion-dollar supply commitment, if confirmed, is what that testing was building toward.
The timing sits inside a memory market that has turned extraordinary. CXMT reported first-quarter 2026 revenue of 50.8bn yuan, about $7.4bn, a rise of more than 700% year on year, and posted a quarterly net profit in the billions of dollars after years of losses.
The surge is the same one lifting every memory maker: AI infrastructure has soaked up DRAM faster than the industry can produce it, and prices have climbed to the point where the chips that go into ordinary consumer devices are being diverted to data centres instead.
For Tencent, locking in domestic supply at scale is partly a hedge against that scarcity and partly a hedge against politics. The dominant memory suppliers are South Korean and American, and US export controls have made Chinese buyers wary of depending on chips that could become harder to obtain. Sourcing from CXMT keeps the supply chain inside the country’s borders, which is the entire point of China’s push for memory self-sufficiency.
For CXMT, a named blue-chip customer at this size is validation in the commercial sense as well as the technical one. The company has been undercutting the established players on price, supplying DDR5 to Western brands including [Corsair](https://thenextweb.com/news/chinese-dram-cxmt-corsair-ddr5-memory-prices), while converting some of its capacity to high-bandwidth memory because the margins there are too good to ignore. A large domestic contract gives it a stable base of demand while it scales.
That scaling is what makes Western buyers nervous and Western suppliers attentive. CXMT’s rise has been rapid enough that companies outside China have started lobbying for access to it, with Apple seeking US approval to buy from the firm as memory prices have quadrupled. A Chinese maker that both alarms Washington and tempts Cupertino is an unusual position to occupy.
What the reported deal does not settle is the terms. The duration, the chip mix between DDR5 and other grades, and the delivery schedule were not disclosed in the Reuters account, and neither CXMT nor Tencent has commented.
The headline figure is the part that travelled. The contract behind it, if and when either side confirms it, will say more about how fast China’s memory industry is closing the gap.
