U.S. data center spending reached a record $40 billion in June, marking a 30% year-over-year increase driven primarily by artificial intelligence and machine learning infrastructure demands. This unprecedented investment surge reflects how AI expansion is reshaping digital infrastructure, with tech giants like Microsoft, Amazon, and Alphabet leading massive facility buildouts while raising critical questions about electricity grid capacity and sustainability.
What you should know: The data center construction boom represents the largest infrastructure investment wave in the sector’s history, with AI serving as the primary catalyst.
- Spending jumped from a 50% increase in 2024 to 30% growth in 2025, according to Bank of America Institute data.
- Tech companies including Microsoft, Alphabet, and Amazon are investing heavily in new and expanded facilities to meet AI computing demands.
- Nvidia, a leading chip manufacturer, has emerged as a key beneficiary, with its GPUs widely used in AI training and inference applications.
Market conditions: North American data center markets are experiencing unprecedented supply constraints despite record development activity.
- Colocation vacancy rates have plummeted to just 2.3%, even as installed capacity rose to 15.5 GW, according to JLL’s midyear 2025 report.
- JLL, a commercial real estate firm, warns the market has reached a “critical tipping point” where soaring demand, limited power, and lengthy build timelines are forcing strategic pivots.
- Cloud providers drove 65% of leasing activity in the first half of 2025.
Geographic distribution: Northern Virginia maintains its dominance as the nation’s data center hub, but other markets are rapidly expanding.
- Northern Virginia leads with 5.6 GW of capacity—over three times Dallas-Fort Worth’s 1.5 GW.
- Current planned development totals 31.6 GW, led by Northern Virginia (5.9 GW), Phoenix (4.2 GW), Dallas-Fort Worth (3.9 GW), and Las Vegas/Reno (3.5 GW).
Looking ahead: Industry analysts project massive continued investment through the decade, but infrastructure challenges loom large.
- JLL forecasts up to $1 trillion in North American data center investment from 2025–2030, with more than 100 GW of potential capacity delivery.
- Rising electricity demand from AI data centers, combined with electric vehicles, industrial reshoring, and building electrification, is expected to challenge utilities and policymakers.
- The rapid growth is forcing a rethink of strategies around balancing infrastructure needs with sustainability and grid reliability.

DOE fusion roadmap targets 2030s commercial deployment as AI drives $9B investment
The Department of Energy has released a new roadmap targeting commercial-scale fusion power deployment by the mid-2030s, though the plan lacks specific funding commitments and relies on scientific breakthroughs that have eluded researchers for decades. The strategy emphasizes public-private partnerships and positions AI as both a research tool and motivation for developing fusion energy to meet data centers' growing electricity demands. The big picture: The DOE's roadmap aims to "deliver the public infrastructure that supports the fusion private sector scale up in the 2030s," but acknowledges it cannot commit to specific funding levels and remains subject to Congressional appropriations.
