Chinese Chip Firms Post Record Revenue as AI Demand and US Export Curbs Drive Domestic Boom

Chinese semiconductor companies posted record revenue in the most recent reporting period, driven by surging domestic demand for AI chips and the unintended consequence of US export restrictions that have pushed Chinese technology buyers toward homegrown suppliers, CNBC reported. Firms including SMIC, Cambricon, and other domestic chip designers have benefited as US restrictions on Nvidia and AMD advanced AI chips have spurred Chinese hyperscalers and AI labs to invest heavily in domestically produced alternatives. The restrictions, which tightened further in late 2025, were intended to limit China's access to leading-edge AI compute but have had the secondary effect of accelerating Chinese chip development and revenue. Huawei's Ascend line of AI accelerators has emerged as the primary domestic alternative to restricted Nvidia products, and demand for those chips has risen sharply. Chinese cloud providers including Alibaba Cloud, Baidu, and Huawei Cloud have expanded their Ascend-based computing clusters significantly. The broader Chinese chip ecosystem -- including foundry services, memory, and packaging -- has seen corresponding demand increases. SMIC, the country's leading contract chipmaker, has expanded capacity to meet orders that previously might have gone to TSMC or Samsung for chips that can no longer be exported to China. US policymakers have argued that tightening restrictions further is necessary to prevent China from closing the capability gap. Chinese industry figures have credited the restrictions with catalyzing the domestic ecosystem faster than market forces alone would have achieved.
