Data Center & AI Infrastructure Stocks

Companies whose revenue or earnings are materially driven by the physical, power, and network infrastructure enabling AI training and cloud computing. Spans data center REITs (EQIX, DLR), power and cooling vendors (VRT, ETN), server OEMs (SMCI, DELL), network switching (ANET, CSCO), power utilities signing AI campus PPAs (NEE, CEG), and AI compute hosting companies (IREN, CORZ).

Equinix (EQIX) is the global colocation leader with network-dense interconnection advantages no competitor replicates. Arista Networks (ANET) dominates AI cluster networking with the highest gross margins in hardware. Vertiv (VRT) is the power and cooling infrastructure play with direct exposure to rising rack power density. Digital Realty (DLR) offers hyperscale campus exposure with a massive pre-leased development pipeline.

Training frontier AI models requires tens of thousands of GPUs running continuously for months. A 100,000-GPU cluster draws 100+ megawatts — roughly the consumption of a small city. Grid interconnect queues in key markets run three to five years. Companies like Vertiv and Eaton that engineer power delivery for high-density racks, and utilities with available capacity adjacent to hyperscaler campuses, become direct beneficiaries of this constraint.

Yes, relative to pure AI chip exposure. EQIX and DLR earn recurring lease revenue independent of which specific AI model or chip architecture wins commercially — their occupancy is driven by the buildout of the entire AI infrastructure layer. They are not immune to hyperscaler capex cycles, but they lack the single-model or single-customer concentration risk of semiconductor plays.

Bitcoin miners like IREN, CORZ, and WULF built out large-scale data center facilities with direct power agreements — the same core asset AI compute needs. As BTC mining margins compress, several are pivoting to offer GPU compute leasing to AI companies using their existing power and colocation infrastructure. This optionality makes them higher-risk but potentially higher-upside AI infrastructure plays.
