Global spending on data centres is projected to reach US$31.6 trillion by 2050 as demand for artificial intelligence (AI) intensifies, marking an unparalleled investment surge, according to a new report by PricewaterhouseCoopers LLP (PwC). This figure could rise to US$50 trillion if AI adoption accelerates beyond the firm’s baseline forecast, exceeding the scale of historical infrastructure projects such as railways, electrification, and the Internet.

With AI integration deepening across consumer, corporate, and governmental sectors, technology companies including Microsoft Corp and Amazon.com Inc, along with smaller data centre operators, are rapidly expanding computing facilities worldwide. The largest share of expenditures will focus on data centre hardware, prominently supplied by companies like AI chip specialist Nvidia Corp.

However, the sector faces growing resistance. At least 75 data centre projects valued at approximately US$130 billion were delayed or blocked in the first quarter of this year due to local opposition. Critics raise concerns about environmental impacts, resource consumption, and broader societal effects of AI, such as potential job displacements.

PwC’s analysis reveals the United States will host nearly half of the total data centre investment at US$15.1 trillion, followed by the Asia-Pacific region at US$8.2 trillion, Europe at US$5.6 trillion, the Middle East at US$1.1 trillion, and Africa at US$255 billion. Spending is expected to grow steadily, with annual global expenditures rising from around US$800 billion in 2026 to US$1.1 trillion by 2030 and US$1.8 trillion by 2050.

The forecast highlights that most capital will be allocated to ongoing hardware upgrades—such as graphics processing units, servers, storage, and networking equipment—rather than the initial construction or land acquisition. This marks a departure from previous technology infrastructure cycles, where upfront investment dominated.

“Railways. Electrification. The Internet. Each required enormous amounts of capital and defined an era,” the report states. “The AI infrastructure cycle underway dwarfs all three. This one resets every four to six years and shows no signs of ending.”

China and India are expected to drive significant incremental demand due to their large populations, rapidly digitizing economies, and substantial potential for AI integration into business and consumer activities. PwC’s projections are based on modeling conducted by Oxford Economics Ltd, which covers 46 countries and territories representing the majority of global economic activity and digital infrastructure investment.

The report emphasizes that the availability and reliability of electricity will be the most critical factor determining where AI infrastructure investments are made. Affordable and increasingly low-carbon power at scale is a challenging prerequisite for many markets. Additionally, semiconductor supply chain disruptions could reduce global data centre spending by nearly 20%. A strengthening emphasis on data sovereignty may also shift investment geographically, though it is not expected to diminish overall global expenditure.
