Key facts
- China delivered capacity 24+ GW; pipeline ~20 GW dated plus ~30 GW announced (≈50 GW under construction or planned); US 56 GW at 2026 year-end
- ByteDance leases about 1/5 of China’s delivered capacity; ByteDance/Alibaba/Tencent/Baidu capex reached ~$20B in Q2 2026, more than double a year earlier
- Inner Mongolia is the leading AI hub (power about half the price of Tier-1 cities, renewables, generous quotas) under the ‘Eastern Data, Western Compute’ policy
- Build speed: a standard 100 MW facility in ~12 months; Alibaba’s modular ‘100-day datacenter’ from shell to servers; Chinese permitting 3–6 months vs 12–13 months in the US
What happened
SemiAnalysis launched a facility-level model of Chinese data centers. The FT’s Oct 8 story brought the numbers to a wider audience.
Why it matters
Compute capacity is the core of the US–China AI race. China has less than half of US capacity today but builds and permits faster, with cheap inland power.
