Statista's Market Insights forecast puts global data center market revenue at approximately $538.91 billion in 2026, spanning the servers, storage and network infrastructure businesses that make up the sector's core hardware spending. The research firm projects that figure will keep climbing at a compound annual growth rate of 8.48 percent between 2026 and 2031, pushing total worldwide revenue to roughly $809.59 billion by the end of that period.

Network infrastructure, the segment covering routers, switches and related connectivity hardware, is expected to represent the largest single piece of the market in 2026 at an estimated $284.01 billion in volume, reflecting the scale of interconnection buildout accompanying new data center capacity. Statista's country-level breakdown shows the United States generating more revenue from data center hardware than any other nation, an estimated $168.51 billion in 2026 alone, reinforcing the country's position as the largest single national market tracked in the forecast.

Statista attributes the sector's growth trajectory to rising demand for data storage and processing capacity, alongside a parallel shift toward energy-efficient and sustainability-focused facility design as operators respond to both cost pressure and regulatory scrutiny. The firm also points to edge computing as an emerging driver, as providers push infrastructure closer to end users to support real-time applications tied to 5G networks and connected devices, a trend expected to shape investment patterns across the market through the end of the decade.
