The Chinese AI Infrastructure Boom: Introducing the SemiAnalysis China Datacenter Model

Key Points:

• China’s datacenter market is rapidly expanding, with over 24GW of capacity tracked across 1,000+ facilities, surpassing EMEA and the rest of Asia, excluding an additional 50GW in pipeline and announced projects.
• Major Chinese tech firms like ByteDance, Alibaba, Tencent, Baidu, and Huawei are driving a surge in AI-related datacenter investments, with combined capex from Alibaba, Tencent, and Baidu reaching $20B in 2Q26, more than doubling year-over-year.
• ByteDance is the largest datacenter tenant in China, occupying about one-fifth of the country’s delivered datacenter capacity, mostly through leasing, making it a key customer for wholesale colocation providers.
• China’s datacenter industry evolved from a telecom-dominated retail model with high vacancy rates to a wholesale AI-driven buildout focused on western hubs under the “Eastern Data, Western Compute” policy, leveraging fast permitting, cheap power, and modular construction techniques.
• Construction speed and cost advantages in China stem from factory-prefabricated modular designs, abundant labor, and supportive state policies, enabling 100MW datacenters to be built in under 12 months, outpacing Western build cycles.
