Why Data Center REITs and Stocks Are the Critical Infrastructure Play in the AI Era

Nebius Surges 18% on Blowout Earnings, AI Data Center Expansion; Can Rally Continue?
Published on: Dec 8, 2025

The explosive growth of artificial intelligence (AI) is often visualized through the lens of advanced semiconductors. However, a more foundational—and potentially more resilient—investment opportunity lies in the physical infrastructure that houses and powers these technologies: data centers. If AI is the new digital brain, data centers are its indispensable central nervous system. This reality is catalyzing a massive capital shift, transforming data center-related stocks and Real Estate Investment Trusts (REITs) from a niche sector into a compelling, standalone asset pool.

The initial market euphoria focused on chipmakers like NVIDIA, but sustained, larger capital flows are now moving downstream to the essential real estate and utility providers. The investment thesis is evolving from “picks and shovels” to “the foundational land and power grid.”

Industry forecasts underscore this monumental shift. According to a report from StoneX, capital expenditure (capex) on AI and data centers by mega-cap tech firms alone is projected to exceed $400 billion in 2025. Broader analysis from independent research firm Dell’Oro Group paints an even more staggering picture: global data center capex is expected to reach $1.2 trillion by 2029.

This level of spending is creating a vast and diversified investment universe. It extends beyond pure-play technology, encompassing industrial, energy, utility, and real estate sectors, thereby forming a unique asset pool characterized by long-term contracts, predictable cash flows, and potential inflation resistance.

For investors, the key is identifying companies with durable moats and high-quality fundamentals. “When selecting the right company to invest in, it’s always important to look at the fundamentals—revenue and balance sheet growth, valuation, occupancy rates, and customer diversification—rather than just technical chart patterns,” advises Roland Chow, portfolio manager at Optura Advisors in Burlingame, California.

A Closer Look at Key Players in the Asset Pool:

  • Equinix Inc. (EQIX): The Interconnection Hub. As the world’s largest data center REIT, Equinix’s paramount value lies in its global interconnection ecosystem. Its network of over 270 data centers serves as the neutral physical meeting point for major clouds (AWS, Azure, Google Cloud), networks, and enterprises. This powerful network effect makes it essential for AI and hybrid-cloud strategies, driving high customer retention and stable cash flow.
  • Digital Realty Trust Inc. (DLR): The Hyperscale Specialist. A fellow REIT giant, Digital Realty excels in providing tailored, large-scale, high-power facilities for hyperscalers like Amazon, Google, and Microsoft. It focuses on high-density colocation and liquid cooling solutions required for AI workloads. Its PlatformDigital and innovation initiatives help clients pre-validate deployments, securing long-term demand.
  • Applied Digital Corp. (APLD): The Pure-Play “AI Factory” Builder. Representing the higher-growth, more speculative end of the pool, Applied Digital is a pure-play on next-generation infrastructure. It focuses on purpose-building “AI factories” from the ground up, optimized for massive GPU clusters. Pivoting from its past, it has secured long-term contracts with AI leaders like CoreWeave, boasting an 84% year-over-year revenue surge in its recent quarter.
  • American Tower Corp. (AMT): The Digital Transmission Backbone. While not a strict data center REIT, this global communications infrastructure leader is a crucial complementary holding. Its portfolio of over 149,000 sites forms the backbone for data transmission. Long-term, escalator-clause leases with telecom tenants generate predictable, inflation-resistant cash flow, with sustained demand driven by 5G rollout and edge computing.

The Bottom Line: The AI race is no longer just about algorithms; it is an arms race for compute infrastructure. Consequently, data center REITs and related stocks are coalescing into a distinct, demand-driven asset class. By carefully selecting within this pool, investors can gain exposure to the long-term growth of AI while potentially benefiting from the defensive characteristics inherent in mission-critical physical assets and long-term contracts.
