For High-Density AI, Available Data Center Space May Not Be Usable
Data Center Knowledge, Tuesday, August 18th, 2026
Vacancy sits near 1% but few facilities support 140-160 kW racks, so AI-ready capacity is scarcer than headline numbers suggest.
Data Center Knowledge argues that headline vacancy figures overstate the capacity actually available for AI workloads.
Vacancy sits at roughly 1%, but very few existing data centers support racks drawing 140 to 160 kW. Liquid cooling availability narrows the usable set further, since air-cooled halls cannot take those densities.
Credit screening by operators narrows options again for tenants without strong balance sheets. The result is that AI-ready capacity is considerably scarcer than the market-level vacancy statistic implies.
