Key Takeaways
- • Data center construction reached a record $45 billion annual rate in December 2025, surpassing office building spending and reflecting the accelerating infrastructure demand from AI workloads.
- • Digital Realty Trust (DLR) and Equinix (EQIX) emerge as the two pivotal data center REITs positioned to capture AI infrastructure growth, with DLR focused on large-scale AI training campuses and EQIX providing global connectivity hubs linking AI technology to end users.
- • Data center REITs offer institutional investors stable, long-term lease revenue streams driven by sustained AI and cloud computing demand, positioning them as reliable passive income vehicles in the 2026 market.
- • Infrastructure REITs including American Tower (AMT), Crown Castle (CCI), Digital Realty (DLR), Equinix (EQIX), and Iron Mountain (IRM) have lagged broader semiconductor gains, with Nvidia appreciating 34.9% year-to-date, creating potential valuation opportunities for contrarian allocators.
Summary
The artificial intelligence infrastructure boom is driving unprecedented demand for data center real estate, with construction spending reaching a record $45 billion annual rate as of December 2025—a milestone that has now surpassed traditional office building expenditures. This structural shift underscores the centrality of physical infrastructure to the AI supercycle and creates compelling investment opportunities within the data center REIT sector for institutional capital.
Digital Realty Trust and Equinix represent the two most strategically positioned players in this market. Digital Realty owns and operates large-scale campus facilities that serve as the backbone for AI model training while simultaneously expanding inference capabilities. Equinix, meanwhile, functions as the critical connectivity infrastructure, providing the hub-and-spoke network architecture that bridges AI technology deployment with global end-user accessibility. Together, these REITs capture both the compute-intensive training phase and the distributed inference phase of AI workload cycles.
Data center REITs derive their investment appeal from predictable, long-duration lease structures that generate stable cash flows insulated from broader economic cycles. Institutional investors view these vehicles as reliable passive income generators, particularly as enterprises continue to migrate workloads to cloud infrastructure and expand AI capacity deployment. The sector benefits from secular demand drivers including increased data consumption, enterprise AI adoption, and the capital intensity of supporting these operations—factors that underpin multi-year revenue visibility.
Notably, infrastructure REITs including American Tower, Crown Castle, Digital Realty, Equinix, and Iron Mountain have underperformed semiconductor stocks in recent periods, with Nvidia generating a 34.9% gain during the comparative timeframe. This relative valuation gap presents potential opportunities for diversified allocators seeking exposure to AI infrastructure with lower correlation to semiconductor volatility while maintaining direct participation in the AI capex supercycle.
