Chinese semiconductor companies posted blockbuster revenues in 2025, turning years of U.S. export restrictions into an unexpected tailwind that has accelerated Beijing’s push for homegrown technology and reshaped supply chains across the industry.
Semiconductor Manufacturing International Corp. (SMIC), the country’s flagship foundry, reported full-year sales of $9.3 billion — a 16 percent jump and the highest in its history. Analysts at LSEG expect the figure to climb above $11 billion this year.
Hua Hong Semiconductor notched a record fourth-quarter revenue of $659.9 million and guided for similar strength in the current period. Domestic GPU hopeful Moore Threads forecast 2025 sales between 1.45 billion and 1.52 billion yuan ($209–220 million), an eye-popping 231 percent to 247 percent increase from 2024. Even more striking was the performance in memory chips.
ChangXin Memory Technologies (CXMT) more than doubled revenue to over 55 billion yuan ($8 billion), according to people familiar with the numbers quoted by CNBC.
The surge reflects a perfect storm of exploding demand for AI infrastructure inside China, a persistent global shortage of memory, and Washington’s tightening export controls that have forced local tech giants to buy Chinese wherever possible.
Paul Triolo, a partner at Albright Stonebridge Group who has tracked the sector for years, called the restrictions “rocket fuel” for Chinese chip demand. What started as an attempt to slow Beijing’s technological rise has instead poured money and urgency into domestic fabs.
Mature-node chips used in electric vehicles and industrial equipment have provided a steady baseline, while advanced components for AI data centers are “through the roof,” Triolo told CNBC.
The memory segment offers the clearest example. High-bandwidth memory (HBM), the specialized DRAM that powers large AI models, remains tightly controlled by the United States. With Samsung, SK Hynix, and Micron largely blocked from selling their latest generations to China, CXMT has stepped into the breach. Its HBM2 and HBM2e products may trail the industry leaders by several generations, but Chinese buyers have embraced them with open arms simply because they are available and produced locally.
Morningstar senior equity analyst Phelix Lee noted that “even the technologically inferior HBM2 or HBM2e are met with enthusiasm” now that foreign supply is restricted. CXMT is on track to begin producing HBM3 this year, a significant step forward.
“After HBM is restricted into China, CXMT is picking up as the only homegrown alternative, so even the technologically inferior HBM2 or HBM2e are met with enthusiasm,” Lee told CNBC.
The skills being honed in memory manufacturing are already spilling over. Triolo pointed out that China’s memory fabs have become unexpected “incubators for advanced process technology” in ways that would have been unthinkable before the October 2022 export controls. The precision required for high-volume DRAM production is sharpening expertise that can eventually be applied to logic chips and GPUs.
Huawei has emerged as the most visible buyer, quietly building an entire domestic semiconductor ecosystem to keep its servers, smartphones, and AI systems running.
“While China does not yet lead in peak GPU performance, these homegrown solutions are filling the domestic ‘compute gap’ and driving record revenues,” Parv Sharma, senior analyst at Counterpoint Research, told CNBC.
However, the picture is far from uniformly rosy. Chinese foundries like SMIC and Hua Hong remain unable to produce the most advanced chips at the scale and yields achieved by Taiwan’s TSMC. They lack access to the latest extreme ultraviolet lithography machines from Dutch supplier ASML, and domestic alternatives are still years from matching that capability. The gap in cutting-edge technology persists even as revenues soar.
There is also the growing risk of overcapacity in older nodes. As Sharma noted, much of the current growth is driven by “import dependence replacement.” Once that wave crests, sustaining momentum will require Chinese firms to climb the value chain into advanced HBM and next-generation logic processes — a far harder task.
Still, the momentum is real and self-reinforcing. What began as a defensive scramble has evolved into a comprehensive, state-orchestrated effort to rebuild entire segments of the semiconductor supply chain from the ground up. Beijing has poured hundreds of billions of dollars into the sector through subsidies, talent programs, and national champions.
The record 2025 revenues show that, in the areas where policy and market forces align, Chinese chipmakers are no longer just catching up — they are scaling at a pace that is forcing the rest of the world to take notice.
