Chinese semiconductor shares rallied on Thursday after artificial-intelligence start-up DeepSeek said it had adapted its latest large-language model to run on a new generation of domestic chips. Cambricon Technologies led the advance, jumping 20% to a record high and pushing its market value above RMB500 billion ($70 billion) for the first time. Chip designers Hygon and VeriSilicon as well as foundries Semiconductor Manufacturing International Corp. and Hua Hong Semiconductor also rose, extending year-long gains that investors attribute to Beijing’s drive for self-reliance in advanced computing. The move followed reports that Nvidia has halted production of its H20 graphics processors for China, intensifying expectations that local suppliers will fill the gap created by US export controls. Separately, Baidu-backed Kunlunxin said it secured orders worth roughly $139 million from state-owned carrier China Mobile. The AI accelerators, compatible with Nvidia’s CUDA software, will be supplied through first-tier vendors including H3C Technologies and ZTE, signaling continued domestic demand for alternatives to US chips.
