The U.S. data center sector continued its rapid expansion in Q3 2025, driven by the explosive growth of artificial intelligence (AI), cloud computing, 5G, and digital services. Total energy consumption reached an estimated 250 terawatt-hours, roughly 11% of national electricity usage. With a 9GW in planned projects seen over this quarter in Northern Virginia alone, data center development is expected to exceed 30GW by the end of the decade.
Despite unprecedented construction levels, the market remains heavily supply-constrained: colocation vacancy rates hover near 1% and preleasing exceeds 90%. Hyperscalers deployed over $350 billion in new capital this quarter, spanning AI-focused campuses, edge deployments, and integrated energy solutions. Cooling and energy infrastructure innovations have become central to operational resilience, efficiency, and sustainability.
