The $3 Trillion Supercycle

Data centre infrastructure is in the middle of an investment supercycle that will require up to $3 trillion by 2030, according to JLL's 2026 Global Data Center Outlook. Roughly 100 GW of new capacity is expected to come online between 2026 and 2030, translating into an estimated $1.2 trillion in real estate asset value creation — and tenants are projected to spend another $1 to $2 trillion fitting out that space with IT equipment.

The Scale of the Infrastructure Buildout

This isn't a projection built to attract venture capital. It's the operational reality of an economy that has staked its productivity growth on artificial intelligence — and is only now discovering that AI runs on electricity at a scale the existing grid was never built to deliver.

Capital spending by the 14 largest publicly traded data centre operators is expected to approach $750 billion in 2026, up from under $450 billion in 2025. That trajectory confirms AI infrastructure has moved well past a niche technology line item — it's now a capital cycle with the scale and duration of a utility buildout.

Surge in Power Demand and Grid Bottlenecks

U.S. data centre power demand could reach 35 to 45 GW by 2030, roughly double 2024 levels. Around 80 percent of that demand remains cloud-based, and JLL research doesn't expect that share to fall below 50 percent in the near or medium term.

Nearly half of all data centre builds planned for 2026 are projected to be delayed or cancelled — not because of a shortage of capital, land, or construction capacity, but because of insufficient power grid infrastructure. It's a bottleneck problem concentrated in the one input no amount of money can accelerate past the physical limits of utility timelines.

Emerging Site Selection and Energy Strategies

Power cost and delivery speed now outweigh connectivity in site selection decisions. Behind-the-meter strategies — on-site wind, solar, and battery storage — are accelerating in deregulated markets, and operators increasingly see BYOP ("bring your own power") as a viable path to hitting delivery targets, a trend reinforced by JLL's research on utility interconnection delays.

The wider 2026 commercial real estate picture remains healthy: multifamily and industrial are strong, retail is steady, and office is recovering in several metro markets, per CBRE's 2026 U.S. Real Estate Market Outlook. But data centres stand apart in capital intensity, power requirements, and development timelines — understanding that distinction may be the single most important task facing a commercial real estate investor this year.
