The data center construction boom powered by generative AI is moving past its early land-grab stage and into a more disciplined, selective, and execution-focused phase. According to Bain’s latest global data center forecast, inference workloads have overtaken model training as the center of gravity for computing demand, while power availability has become a more critical constraint than chip supply. Hyperscalers continue to raise capital spending, but deployments are becoming more deliberate, with capital flowing toward assets that can deliver stable returns and clear growth trajectories.
The investment logic is shifting accordingly. Scale is no longer the sole measure of success; the ability to navigate complex variables such as power access, site selection, and customer mix will determine the winners in the next phase. Two avenues stand out for investors. The first is REITs with high-quality data center properties and long-term leases, which can offer relatively stable rental income. The second is critical infrastructure suppliers that provide power management, networking equipment, cooling systems, and reliable electricity—businesses directly exposed to the hard demand created by expanding compute capacity. Below are several representative companies, separated into REITs and stocks.
Market cap $71 billion, forward dividend yield 2.6%. As one of the largest data center platforms globally, Digital Realty operates more than 300 data centers and serves over half of Fortune 500 companies, including Amazon Web Services, Microsoft Azure, and Google Cloud. In the second quarter of 2026, the company signed two hyperscale leases with annualized rent of roughly $205 million. Additional signed bookings are expected to generate about $208 million per year. Revenue has increased year over year for two consecutive quarters.
Market cap $103 billion, forward dividend yield 1.9%. Equinix operates 281 data centers across six continents, functioning as a neutral interconnection hub that links major networks, cloud providers, and enterprises. In the second quarter of 2026, recurring revenue grew by double digits, margins improved, and management raised its full-year financial outlook.
Market cap $160 billion, forward dividend yield 1.1%. This intelligent power management company supplies backup power, electrical systems, data cables, and electronic components used in data centers. Second-quarter 2026 sales rose 21% year over year to a record $8.5 billion. The company said data centers remain a key growth driver, benefiting from strong demand, and it raised full-year organic growth guidance.
Market cap $238 billion. Arista provides networking equipment that connects users, data centers, and the cloud. Second-quarter 2026 revenue surpassed $3 billion for the first time, up 37.7% year over year. In June, the company introduced a new generation of switches built for large AI deployments, supporting faster data connections and lower power consumption to address rising electricity demands in AI data centers.
Market cap $98 billion, forward dividend yield 0.1%. Vertiv supplies the power, cooling, and service infrastructure that keeps data centers running. Second-quarter 2026 net sales rose 24% year over year, and adjusted operating profit jumped 51%. The company expects roughly $14 billion in full-year net sales, implying about 31% organic growth. As a picks-and-shovels play on AI data centers, Vertiv may be less prominent than semiconductor chips, but it is essential for scaling compute capacity.
Market cap $97 billion, forward dividend yield 0.6%. As the largest nuclear power operator in the United States, Constellation Energy benefits directly from data centers’ need for stable, clean electricity. In February 2026, the company reached an agreement with data center developer CyrusOne to supply 760 megawatts to a new facility in Texas. Combined with a previous 400-megawatt deal, Constellation now has 1,160 megawatts under contract for CyrusOne data centers in Texas. Strong second-quarter results led management to raise full-year guidance.
Bain’s report indicates that construction growth has begun to stabilize. Future winners will be defined not by size alone but by precision in managing complexity. With power availability as the critical gatekeeper, companies with reliable electricity supply and efficient infrastructure offerings may hold greater bargaining power in this phase. Investors can participate in the long-term data center trend through the REITs and stocks above, but should pay attention to valuations, capital expenditure pacing, and execution risks.
