There is a quiet landlord behind the artificial intelligence boom. It owns the expensive, power-hungry buildings where the digital economy lives. A recent report from the Colorado Legislative Council Staff highlights the staggering scale. A single data center in operation can demand over a gigawatt of electricity. That is enough to power roughly 750,000 homes. This physical infrastructure, the land, fiber, and massive power hookups, represents a critical and lucrative asset class.
For investors, four U.S. listed real estate investment trusts, or REITs, have positioned themselves as the toll collectors. They are American Tower, Iron Mountain, Digital Realty, and Equinix. Each collects rent from the companies racing to build and deploy AI. Each pays a quarterly dividend supported by operating cash flow. The starting yields are modest. The real story is their potential for dividend growth, fueled directly by this technological transformation. Let us examine the safety of these payouts and the forces that could threaten them.
American Tower (AMT)
American Tower trades under the ticker AMT. The company owns more than 148,000 communications tower sites, leasing them to wireless carriers on long term contracts. Through its CoreSite subsidiary, it also operates a network of heavily interconnected U.S. data centers. The tower business still generates most of its revenue, but the data center segment is growing faster. In the second quarter, data center revenue increased 13.4% year over year to $297 million. Property revenue in the U.S. and Canada fell 2.5%.
At a recent price of $188.97, the stock offers a yield of 3.93%. This is the highest in this group. The quarterly payout is $1.79 which annualizes to $7.16 per share. Dividend safety looks robust. Management raised its full year guidance for adjusted funds from operations, or AFFO, to a range of $11.00 to $11.17 per share. This figure comfortably covers the annual dividend. Second quarter free cash flow reached $1.158 billion, an 18.5% increase. The quarterly distribution cost about $834.1 million. Net leverage sits at 4.9 times, within the company’s target range. The chief financial officer has stated that supporting a growing dividend is the top capital priority.
The payout has a clear growth trajectory. It was reduced from $1.70 to $1.62 at the start of 2024. It then climbed back to $1.70 in 2025 and reached the current $1.79 in 2026. The bull case hinges on CoreSite. Chief executive Steven Vondran noted that these campuses have become critical hubs for AI traffic. Nine of the top ten AI companies are already tenants. The company raised its 2026 data center growth outlook to about 15%. It expects strong yields on new CoreSite investments. The primary risk is customer turnover. DISH Network related cancellations reduced U.S. and Canada property revenue by $63 million last quarter. This churn continues to pressure the largest segment.
Iron Mountain (IRM)
Iron Mountain uses the ticker IRM. Its foundation is physical records storage. The company manages over 735 million cubic feet of documents across roughly 1,300 facilities. The average storage box stays for about fourteen and a half years. This provides steady, predictable rent. It funds newer ventures like data centers and IT asset management. Iron Mountain now operates 31 data centers across 21 markets. Potential capacity is about 1.4 gigawatts. Data centers, digital solutions, and asset lifecycle management together contribute 35% of total revenue. Overall revenue grew 18.5% last quarter. Data center revenue specifically jumped 38.8% to $262.9 million.
The shares yield 2.94% at $109.94. The quarterly dividend is $0.864, or $3.456 per year. Safety metrics appear solid. The trailing four quarter AFFO payout ratio was 60%. This aligns with management’s target in the low 60s. Full year AFFO per share guidance was raised to between $5.87 and $5.93. The company calls its latest 10% increase the fourth consecutive annual raise. The quarterly rate has climbed from $0.65 to $0.715, then $0.785, and now $0.864. Net lease adjusted leverage ended the second quarter at 4.8 times.
Demand is strong. Data center leasing reached 110 megawatts year to date through July. The backlog supports an additional $370 million of revenue beyond 2026. Chief executive William Meaney said recent deals in London and Amsterdam resulted directly from its expanding AI inference pipeline. Records retention remains high at 93.4%. The main concern is the balance sheet. Shareholders’ equity is negative $955 million. Net debt stands at about $17.3 billion. A recent bond carries a 6.25% coupon, signaling rising interest costs. The finances are extended.
Digital Realty (DLR)
Digital Realty is a pure play data center REIT, ticker DLR. It owns 309 facilities across more than 55 markets and 30 countries. Installed IT capacity is about 3.0 gigawatts, with 6.3 gigawatts more planned. It serves over 5,500 customers with colocation, interconnection, and hyperscale leases. Quarterly revenue grew 29.9% year over year, the fastest pace among these four companies.
The stock yields 2.77% at $172.38. The quarterly dividend is $1.22, or $4.88 annually. The dividend looks very secure. Second quarter core funds from operations, excluding promote income, was $2.13 per share. That is a 14% increase and well above the $1.22 payout. Debt to adjusted EBITDA is 4.7 times, below the company’s long term ceiling of 5.5 times. Liquidity is near $6 billion. The dividend record stretches back to 2004. The payout has been flat at $1.22 per quarter since 2022. With FFO growing and the dividend static, coverage is expanding noticeably.
The growth pipeline is clear. Total backlog hit a record $1.9 billion at full share. Chief executive Andy Power said strong hyperscale leasing drove the backlog to a new high, derisking future growth. This backlog provides clear visibility into future cash flow. Investors should note one item. Quarterly reported earnings fell 58.7% year over year. For REITs, FFO is the superior measure of dividend coverage. However, a drop that large in reported earnings warrants attention as development costs and depreciation accumulate.
Equinix (EQIX)
Equinix trades on the Nasdaq under EQIX. It operates more than 270 data centers in over 70 markets. Revenue comes from colocation space, power and cooling, interconnection services, managed infrastructure, and hyperscale joint ventures called xScale. Quarterly revenue grew 16.7%. The second quarter saw a record 9,700 net new interconnections.
At $955.03, the yield is 1.98%. The quarterly dividend is $5.16, annualizing to $20.64. Equinix employs the most conservative payout policy in this group. Management targets a 50% AFFO payout ratio. AFFO per share guidance for the year is $42.69 to $43.29. Net leverage is 3.6 times adjusted EBITDA. Liquidity is about $7.7 billion. The regular quarterly dividend has increased every single year since its inception. It has risen from $1.69 in 2015 to the current $5.16 in 2026.
The growth commitment is explicit. Management expects dividend per share growth to roughly match AFFO per share growth. It projects 9% to 12% annual AFFO per share growth from 2027 through 2029. Chief executive Adaire Fox-Martin stated that eight of the top ten AI model providers and eight of the top ten neo clouds run key networking workloads on Equinix today. The risk is capital intensity. Capital expenditure guidance is $5.0 to $6.0 billion for 2026. It is projected at $5.0 to $7.0 billion annually through 2029. Leverage is expected to rise by about one turn over that period as the company builds to meet demand.
