Yes, the core claim holds up. Bloomberg and Sightline Climate reports from April 2026 show nearly half of planned US data center capacity for this year (~12 GW) faces delays or cancellation risk. Only about one-third is actively under construction.
Bottlenecks are real: power grid limits, transformer/electrical equipment shortages, and supply chain issues. Some projects cancelled, many still on paper.
The exact "120 builds" figure isn't in the main reports (they track GW capacity, one noted ~140 projects), but the overall picture matches. AI demand stays strongโhyperscalers are ramping capex hard. The slowdown is supply-side execution, not lack of interest.
