The Datacenter Supercycle: $7 Trillion in Infrastructure Is Being Built Right Now

Construction starts surged 190% in 2025. Hyperscalers are each targeting $80–100 billion in annual capex. The buildout is accelerating into 2026 — but power, land, and grid capacity are running out...

There is no comparable precedent in the history of commercial real estate or infrastructure construction. U.S. datacenter construction starts hit an estimated $77.7 billion in 2025, a 190% year-over-year increase, according to ConstructConnect’s February 3, 2026 report.

Average monthly spending on datacenter starts grew from roughly $500 million in mid-2021 to $6.5 billion in December 2025 alone. The Stargate Project — the joint venture between OpenAI, SoftBank, Oracle, and MGX announced at a White House press conference in January 2025 — pledged $500 billion over four years for AI infrastructure. It is the largest private infrastructure commitment in U.S. history.

Hyperscaler Arms Race

The five largest hyperscalers — Amazon Web Services, Microsoft Azure, Google, Meta, and Oracle — are projected to spend as much as $602 billion collectively on data center infrastructure in 2026 alone. This level of investment would have seemed unimaginable just a few years ago. Each of the Big Four is now targeting annual capital expenditures in the range of $80 to $100 billion, reflecting how central infrastructure has become to their AI and cloud strategies.

Amazon’s total capital expenditure in 2025 surpassed $100 billion, marking a 78 percent year over year increase. Microsoft reached $44.5 billion, up 58 percent, while Alphabet invested $52.5 billion, up 63 percent. These are not incremental increases. They represent a structural shift in how aggressively these firms are building capacity.

Looking further ahead, McKinsey projects that global data center capital expenditure could reach $7 trillion by 2030, with roughly 70 percent of that coming from hyperscalers. The scale of spending makes it clear that AI infrastructure is no longer a side bet. It is becoming one of the largest coordinated capital deployment cycles in modern technology history.

“Committed supply has increased more than six times since 2019, while live capacity has grown at a far slower pace.”

The Power Bottleneck

Capital is no longer the main constraint in the data center boom. Power is. CBRE data shows that vacancy rates in primary markets have fallen below 2 percent, and about 80 percent of the capacity currently under construction is already pre leased. In many regions, demand is outpacing the ability to deliver electricity fast enough to support new facilities.

Virginia is a clear example. Data centers now account for roughly 26 percent of the state’s total electricity consumption. The strain is not isolated. The PJM electricity market, which stretches from Illinois to North Carolina, attributed a $9.3 billion price increase in its 2025 to 2026 capacity auction directly to data center demand. For households in affected states, that translates to an additional $16 to $18 per month on residential electricity bills.

Looking ahead, Goldman Sachs estimates that approximately $720 billion in grid upgrades will be required through 2030 just to accommodate the ongoing buildout. The constraint is no longer about raising capital. It is about securing and expanding the physical energy infrastructure that powers the digital economy.

Geography Is Being Redrawn

Virginia is leading U.S. data center construction in 2025 with $15.3 billion in starts, closely followed by Louisiana at $15 billion. Mississippi and Texas are not far behind, with $13.9 billion and $13.4 billion respectively. What is especially interesting is where this growth is happening. Sixty four percent of the capacity currently under construction is in what JLL calls “frontier markets,” meaning locations outside the traditional hubs like Northern Virginia, Silicon Valley, and Chicago. The buildout is clearly spreading beyond the usual clusters.

The energy impact is also becoming significant. In Ireland, data centers already account for 21 percent of national electricity consumption. The International Energy Agency projects that this could rise to 32 percent by 2026, underscoring how closely digital infrastructure and power systems are now linked.

Capital flows reflect the same momentum. Announced foreign direct investment in the data center sector surpassed $270 billion in 2025, representing more than one fifth of all global greenfield investment, according to UNCTAD’s January 2026 report. This is no longer a niche asset class. It is becoming a core pillar of global infrastructure and investment strategy.
