ByteDance rents a fifth of China's 24-gigawatt datacenter fleet, and no filing shows it

The first building-level count of China's AI infrastructure↗ breaks both lazy assumptions about the market at once: China is far bigger than the trade assumed, and the empty part belongs to the last boom, not this one ¹.

Only America runs more capacity

Published estimates of China's datacenter capacity differ by 15x, because the biggest tenant files no 10-K and several of the largest landlords have never listed ¹. SemiAnalysis mapped 1,000-plus facilities across more than 60 operators and counts over 24GW live, behind the US at 56GW and ahead of EMEA and the rest of Asia, with 20GW of dated pipeline and 30GW of announcements on top ¹.

The vacancy camp is citing the last boom

The empty camp's evidence is real: market power rates were cut in half from about $80/kW/month, and GDS told investors in August the price reset needs 18 more months to digest ¹. But that describes the telecom-era retail stock near Tier-1 cities, running 30–50% utilization ¹. The AI fleet is wholesale and fills fast, back above 70% utilized against that 30–50% legacy range; even the leading colocation player's own retail segment sits near 60% ¹. VNET's June-quarter filing↗ matches: 1,007MW of wholesale in service, 73.9% utilized, 862MW of orders won in the half ². Around Ulanqab, Inner Mongolia, nearly 100 datacenters have opened or broken ground since 2016, carrying 12.5GW of pledges, most in the past year ³. The buildout is going up next door to the vacancy.

Three giants now spend more than they earn

SemiAnalysis counts $20B of June-quarter capex from Alibaba, Tencent and Baidu, more than double a year earlier, and records all three free-cash-flow negative in the same quarter for the first time ¹. The filings confirm two of the three: Tencent's capex rose 176% to 52.8bn yuan↗, about $7.8B, swinging free cash flow to a 13.8bn yuan outflow, its first since 2005 ⁴⁵; Alibaba burned RMB44.73bn of free cash flow↗ against RMB67.7bn of capex, halfway through a 380bn yuan plan ⁶.

The National Bureau of Statistics shows the same split economy-wide: internet firms' equipment spending up 81.8% in the first seven months, total fixed-asset investment down 6.7% ⁵.

The tenant nobody tracks pays the landlords nobody lists

ByteDance, the biggest spender, lifted its 2026 capex target above 200bn yuan, about $29.6B, half for chips ⁵. SemiAnalysis puts its footprint at about a fifth of delivered national capacity, nearly all rented: one private company is the anchor tenant of the whole wholesale market ¹. Its chatbot Doubao passed 200 million daily users this month↗ ⁷. The US-listed landlords GDS and VNET signed 1.3GW of wholesale orders in the first half yet captured barely a third of ByteDance and Alibaba orders since 2024 ¹.

The grid gets the money, the chips set the limit

The state is the other collector: the 15th Five-Year Plan lifts grid investment 40% to more than $746B, State Grid alone committing 4tn yuan through 2030 ¹⁸. What money cannot fix is silicon. A 50% domestic-chip mandate has bound datacenters since August 2025, and the 400,000 Nvidia H200 units approved for ByteDance, Alibaba and Tencent exist because domestic chips still cannot train frontier models ⁵. SemiAnalysis calls the buildout chip-gated, not power-gated ¹.

The dated tells: whether Alibaba and Tencent stay free-cash-flow negative in the September quarter, and whether VNET can carry RMB10–12bn of capex this year on RMB7.2bn of cash and RMB19.2bn of long-term debt ².
