Data Center Vacancies Plummet Amid Power Supply Constraints

Data center vacancy rates in North America have plummeted to 2.3%, with major markets experiencing rates below 1%. The demand for cloud and AI services has driven up rents by 50% in the last five years, despite supply doubling or tripling. Enterprises are securing capacity 18-24 months in advance due to the capacity crunch, expected to persist through 2027.

Data center availability in North America has seen a significant drop during the first half of 2025, with vacancy rates falling to an historic low of 2.3% across the region, according to JLL. In major markets such as Northern Virginia, rates have dipped below 1%, marking a substantial shift in the market landscape [1].

The surge in demand for cloud and AI services has been a primary driver behind this trend. Over the past five years, rents have increased by 50%, even as supply has doubled or tripled in major regions [1]. Enterprises are now securing capacity 18 to 24 months in advance due to the ongoing capacity crunch, which is expected to persist through 2027 [1].

The demand for colocation space has been particularly intense, with nearly three-quarters of the current pipeline under prelease agreements. Enterprises are increasingly adopting a proactive approach, securing capacity well before deployment to avoid missing out on limited availability [1].

The data center industry has seen substantial growth, with a 161% increase in market cap from 2019 to 2025, driven by insatiable tenant demand and limited supply [2]. The market's expansion is fueled by the accelerating adoption of cloud technologies, AI, and ML applications, as well as the need for scalable and secure infrastructure [3].

The market's growth is also driven by the rising investments in data center infrastructure. According to Dell’Oro Group, cloud service providers poured roughly $450 billion into data center infrastructure last year, with expectations of continued growth at a CAGR of 21% year over year, surpassing $1 trillion by 2029 [1].

Hyperscale cloud providers have been at the forefront of this expansion, accounting for nearly two-thirds of all colocation leasing activity in North America during the first half of 2025 [1]. These providers are rapidly gobbling up global compute capacity, with projections showing they will own more than 60% of global capacity by 2030 [1].

However, the rapid growth in data center demand has also brought challenges, including grid limitations and electricity cost increases. While the colocation construction pipeline has increased significantly compared to five years ago, average wait times for a power connection in the U.S. have risen to four years, and electricity costs have increased nearly 30% in the same period [1].

Despite these challenges, the data center market continues to grow, with North America absorbing 2.2GW in the first half of 2025, almost entirely through preleasing [2]. The market's resilience and growth potential make it an attractive investment opportunity for financial professionals and investors.
