Data Center Construction Set for $3 Trillion Investment Supercycle
The global data center sector is entering a significant investment cycle, with spending projected to reach $3 trillion between 2026 and 2030. This expansion is driven by rising demand for AI and cloud infrastructure. JLL's 2026 Global Data Center Outlook anticipates the addition of nearly 100 GW of new capacity by 2030-doubling current infrastructure. The report estimates roughly $1.2 trillion in real estate value and $870 billion in debt financing will support this growth. Tenants are expected to allocate $1-2 trillion for upgrades to GPU and networking infrastructure. Moody's confirms this trajectory, forecasting at least $3 trillion in global data center expenditure in the same period, led by hyperscale construction, despite increasing costs and pressure on power resources.
Background
Data center development is accelerating due to exponential growth in AI workloads and cloud services. McKinsey projects global data center capacity will triple by 2030, with AI accounting for about 70% of this increase. This highlights AI's pivotal role in driving infrastructure demand. Modularity is emerging as a key construction approach. JLL forecasts global annual sales of modular and micro data centers could reach $48 billion by 2030, reflecting a shift toward prefabricated, scalable systems. The push to shorten project timelines, address compute density needs, and manage inflation and grid constraints is advancing these modular and automation-led strategies.
Details
JLL's report notes 97% global data center occupancy and that 77% of new construction is already pre-committed by tenants, suggesting resilient market fundamentals despite overheating concerns. Modular construction delivers clear advantages, such as reducing on-site build times, improving cost control, and rapidly deploying AI-ready infrastructure. Market analysis shows the modular data center sector grew to $38.1 billion in 2026, up from $28.4 billion in 2025. It is forecasted to reach $72.96 billion by 2030 and $176.41 billion by 2035, reflecting a 17.6% compound annual growth rate. North America accounts for about 41% of the market, with modular deployments achieving up to 85% faster rollouts compared to conventional builds.
Technologies like digital twins and AI-assisted planning are transforming project execution. Digital twin platforms enable virtual simulation of power, cooling, and layout, potentially shortening project timelines by 30% and reducing cooling energy consumption by about 20%. Liquid cooling systems, edge-ready micro facilities, and advanced energy management are becoming standard in new builds, supporting GPU-intensive AI workloads that require high rack densities and improved power efficiency.
Outlook
The next several years will likely bring faster deployment of modular, AI-focused data centers. Regional assembly hubs and digital automation will drive speed and capital efficiency. Aligning infrastructure investment with power grid capabilities and workforce readiness will be critical as the sector experiences unprecedented global growth.
