U.S. Data Center Boom Faces Political Gridlock Amid Surging AI Demand

Never before have data centers been built at such a pace: right now in the US there are 7,481MW of capacity under construction – 24.8% more than in the first half of 2024 when that record was set. But, although there is space under development that is leased faster than it is developed, in reality there is a shortage of supply of ready-to-occupy space in key markets.

Of the 7,481 MW of new data-center space under construction in the first half of 2026 in the U.S., more than 80% has already been leased, leaving only about 1,500 MW or so for immediate leasing — or roughly 6 months’ supply at current rates of deployment into new space of various sizes in primary markets. The ready-to-occupy space vacancy rate for all types of data-center space in U.S. primary markets has plummeted to just 1.4%.

As AI takes over, a new bottleneck develops: the physical space to power it all. No longer just a matter of raising capital or attracting customers, a host of physical and bureaucratic impediments (e.g., electricity availability, transmission upgrades, water, land, permits and connectivity to influential decision-makers) now dictate the specific location of individual data centers.

Still, there is a great deal of regional variation and hot markets. Northern Virginia has the lowest vacancy rate of 0.2% while Atlanta is currently the #1 construction market with 2,900MW under construction. In other words, while developers are increasingly forced to look to greenfield sites, they are still opting for locations that can handle their power needs and that have sufficient permitting to enable development of large sites.

Opposition to data center projects is gaining traction across the political aisle. Concerns related to power consumption, environmental impact, local strain and tax incentives are driving a variety of moratoriums and stricter permitting. While New York has banned data centers for two years, Pennsylvania is mandating more transparency into the permitting process and Texas is tightening up the approval process in several areas of the state.

Until all these hurdles are overcome, the theoretical pipeline capacity will not be converted into operational capacity. Furthermore, these impediments are adding a layer of uncertainty to what is already a very challenging supply environment.

Rents for data centers looking for space of3 MW or larger at 10 kW or higher are rising by 8.3% in the first half of 2026. While there is plenty of capital available to build the large number of data centers required to handle the growth in AI, and there is demand for space, the real issue for developers today is the increasing complexity of the regulatory environment and how to navigate through it to get a new data center up and running in a timely manner to deliver returns on investment.

What This Means for Investors and Developers:

1. Choose markets with a stable or favorable permit environment and sufficient power. In these regions, rents will continue to rise sharply while supply is at an all-time low.
2. Be aware of state-specific issues and how new legislation can have a dramatic impact on your deployment timeline and ROI. For example, the recent moratorium in New York or the new transparency rules in Pennsylvania can have a significant effect on a developer’s ability to deploy in these markets.
3. Build quality into your land selections. Land with “Infrastructure Deficits” or Communities in opposition to Data Centers will only serve to create unexpected delays to your Development timetable.
4. Local stakeholders must be engaged early in the development process to build relationships with key groups including local government, local utilities and neighbors. Developing positive relationships can reduce regulatory roadblocks.

The politics of permitting and the adequacy of infrastructure will become as important a factor as funding and technology in determining the growth of data center real estate in the years ahead. And investors will need to consider which of the major data center markets will be open for business and which will be closed off to growth as demand for facilities to house AI continues to soar.
