Data center rents rise as AI demand outpaces supply

Global data center operators are adding capacity at unprecedented rates, yet demand from AI workloads and hyperscale cloud providers continues to outstrip supply. CBRE’s 2026 report, released today, highlights record-low vacancy rates across key North American markets and warns that power shortages will delay meaningful new capacity until at least 2036. The result is rising rents, shifting site strategies, and growing interest in emerging markets as operators compete for land and electricity worldwide.

What the report shows

CBRE’s data reveals a stark mismatch between inventory growth and demand. In the first quarter of 2026, Latin America’s leading data center markets expanded inventory by 41.3% year-over-year, yet vacancy rates remained tight. North American markets, which account for the bulk of global capacity, saw similar trends, with operators reporting historic lows in available space. The report attributes the squeeze to a combination of sustained AI-driven demand and delays in power infrastructure, which are pushing new projects years into the future.

Operators are responding by adjusting site plans and exploring secondary markets. Some are relocating facilities to areas with better power availability, while others are investing in modular designs to accelerate deployment. The report notes that these shifts are not just tactical but structural, reflecting a long-term rebalancing of the industry’s geographic footprint.

Why the shortage persists

The core issue is not a lack of construction but a lack of power. Data centers built for AI workloads require significantly more electricity than traditional facilities, and grid capacity in many established markets is already maxed out. CBRE’s projections suggest that even with aggressive investment in renewable energy and grid upgrades, new capacity will not come online fast enough to meet demand before the mid-2030s. This bottleneck is particularly acute in North America, where hyperscale providers and AI startups are competing for the same limited resources.

Emerging markets in Latin America, Southeast Asia, and Africa are benefiting from this dynamic, as operators seek alternatives to saturated hubs. However, these regions face their own challenges, including regulatory hurdles, limited infrastructure, and higher operational risks. The report cautions that while these markets offer growth potential, they are unlikely to fully offset the supply constraints in mature regions in the near term.

What it means for the industry

For data center providers, the current environment presents both challenges and opportunities. Rents are rising, but so are costs, particularly for power and land. Operators with existing capacity in high-demand markets are well-positioned to capitalize on the shortage, while those looking to expand face stiff competition and longer lead times. The report suggests that mergers and acquisitions may accelerate as smaller players struggle to secure the capital needed for new builds.
