The global data center market is forecast to generate 572.99 billion dollars in revenue in 2026, according to Statista, underscoring how quickly the industry has grown alongside demand for cloud computing and artificial intelligence services. Cloud IT infrastructure spending alone is projected to reach 133.7 billion dollars for the year, reflecting continued investment by major technology companies in the physical systems that support their online services.

Rising costs are also reshaping the market. Construction expenses for data centers in London reached 12.02 dollars per watt in 2025, a benchmark figure that illustrates how land, power infrastructure and specialized equipment have driven up the price of building new capacity in dense urban markets. Developers in other major hubs face similar pressures as competition for suitable sites and grid connections intensifies.

Space in existing facilities remains tight as well. Northern Virginia, widely regarded as the world's largest data center hub, reported the lowest vacancy rate among major global markets as of the first quarter of 2025, leaving many prospective tenants with limited options and longer waits for available capacity.

Despite those constraints, supply continues to expand rapidly. Global data center supply was expected to grow by more than 20 percent in 2025 alone, as developers race to bring new capacity online even as construction costs climb and available space in established markets stays scarce.
