The United States hosts more data centers than any other country, accounting for roughly 46 percent of facilities listed worldwide, according to figures compiled by Statista from the Cloudscene platform. As of May 2026, the platform listed 5,427 data centers in the United States, far ahead of Germany at 529, the United Kingdom at 523, China at 449, and Canada at 337.

The facility count tracks with market value. Statista's Market Insights forecast puts US data center market revenue at $187.94 billion in 2026, the largest of any country, out of a projected $573 billion worldwide. The market spans servers, storage, and network infrastructure, with key hardware suppliers including Dell, HPE, and Cisco.

Statista's analysts attribute the concentration of American facilities to the country's large digital economy, advanced technological infrastructure, and the rapid adoption of cloud computing, big data analytics, and artificial intelligence. Demand for low-latency edge computing and Internet of Things connectivity is also driving new construction.

The figures count facilities rather than capacity, and Statista notes that individual sites vary widely in size, with hyperscale campuses housing far more computing power than smaller colocation buildings. Even so, the gap between the United States and the rest of the world has widened in recent years as hyperscale operators continue to expand domestic footprints, a trend reflected in the wave of multi-billion-dollar campus announcements across Sun Belt states.
