The cost of building AI-optimized data center facilities has reached a new threshold in 2026, with per-megawatt construction costs hitting approximately $20 million for facilities designed to support high-density GPU workloads — nearly double the $11.3 million per megawatt required for standard enterprise data centers. The cost differential reflects the need for more robust power distribution systems, advanced liquid cooling infrastructure, denser rack configurations, and reinforced structural systems capable of supporting high-weight server deployments. Per-square-foot costs tell a parallel story of rapid escalation. Industry data compiled from active project records shows construction costs rose from $183 per square foot in 2020 to $415 by 2025, and reached approximately $1,033 per square foot by the end of 2025 for premium AI-ready builds. Supply chain pressures on switchgear, transformers, and specialty cooling equipment have been primary contributors to that acceleration, compounded by elevated labor costs in markets where multiple large-scale projects compete for the same electricians and structural crews simultaneously. January 2026 recorded the highest single-month data center construction start volume since industry tracking began, with $25.2 billion in new projects breaking ground nationally. The Southeast — led by Georgia, North Carolina, South Carolina, and Tennessee — is projected to account for approximately 35% of total U.S. data center capacity by 2030, up from a smaller regional share a decade ago. U.S. data center facilities currently operate with a combined capacity exceeding 50 gigawatts, a figure that S&P Global projects will nearly double by 2030 driven by AI infrastructure demand. Data center development firms and operators communicating capacity investment, leasing milestones, and construction progress to enterprise customers benefit from Rely on Content's content strategy for data center operators services, which translate complex infrastructure projects into clear, credible business narratives.
