Chinese AI Chipmakers Claim 41% of Domestic Market as Nvidia's Lead Shrinks, IDC Finds

Chinese GPU and artificial intelligence chipmakers captured approximately 41% of China's AI server market in the most recent period tracked, according to data from research firm IDC cited by Reuters, a significant gain that reflects both the effect of US export restrictions on Nvidia and the maturation of domestic alternatives. Nvidia still holds the largest single share of China's AI chip market, but its dominance has eroded as Chinese companies including Huawei's HiSilicon, Cambricon, Moore Threads, and Biren Technology have scaled production and improved the performance of their AI accelerators. US export controls implemented in 2022 and tightened in 2023 have prevented Nvidia from selling its most advanced H100, A100, and H20 chips into China, creating a structural opening for domestic competitors. Huawei's Ascend chips have been the primary beneficiary, with the company reportedly ramping production of its Ascend 910B and newer variants to meet demand from Chinese technology companies and state-affiliated organizations that can no longer access Nvidia hardware. The 41% domestic market share figure marks a meaningful milestone. A year prior, Chinese chipmakers held an estimated 25 to 30 percent of the local AI server market. The shift has been accelerated by Chinese cloud providers including Alibaba Cloud, Baidu, and Tencent prioritizing domestic chip sourcing to reduce geopolitical supply chain risk. Nvidia has adapted by offering China-compliant chips designed to fall under export control thresholds, but those products carry lower performance specifications and have not fully substituted for restricted hardware. The IDC data is likely to intensify debate in Washington about the effectiveness of chip export controls as a tool for slowing Chinese AI development.
