# SemiAnalysis: China has 24+ GW of data-center capacity (US

Full title: SemiAnalysis: China has 24+ GW of data-center capacity (US: 56 GW by end-2026), ~50 GW more in the pipeline; ByteDance uses a fifth

SemiAnalysis's China Datacenter Model (Sept 25, 2026; tracking 1,000+ facilities from 60+ players) puts China's delivered data-center capacity at over 24 GW, more than EMEA and the rest of Asia combined, against 56 GW in the US by end-2026. About 20 GW of dated pipeline and 30 GW of announced projects follow. ByteDance occupies about one-fifth of Chinese capacity. The FT reported the figures on Oct 8.

## 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.
