Background
hyperscale refers to a class of data centre designed to scale computing resources rapidly and efficiently to support massive workloads, principally public cloud services, AI training, and large-scale content delivery. The defining characteristics are size (typically 100 MW or more of IT load), standardised modular design, very high server density, and ownership by a major cloud or technology company rather than a colocation provider.
As of 2025, the five largest hyperscale operators, Amazon, Microsoft, Google, Meta, and Apple, account for the majority of global data centre investment. The IEA's April 2026 report found these five collectively exceeded $400 billion in capex in 2025, expected to rise 75% in 2026 to approximately $700 billion. Synergy Research Group tracks hyperscale facility count and capacity as a market indicator.
The AI training wave has elevated hyperscale's power and land requirements beyond what earlier designs assumed. A conventional hyperscale facility of 2018 vintage might draw 100 to 150 MW; AI-optimised hyperscale campuses of 2025 to 2026 are being designed for 500 MW to 1 GW, and the Stargate US programme involves campuses at 1.2 GW. This scale increase is the primary driver of grid-connection constraint and behind-the-meter generation demand.
