Realty Income vs. Digital Realty: Which REIT Has Better Upside Now?

Realty Income (O) and Digital Realty (DLR) represent two distinct REIT bets: O as a defensive, income-focused portfolio with ~98–99% occupancy across 15,500+ properties, steady Q3‑2025 revenue growth and a long track record of monthly dividends, and DLR as a growth-oriented data‑center operator benefitting from AI/cloud demand (50%+ of recent bookings), with Q3‑2025 revenue +10%, FFO/shr +13%, >$850m backlog and a 5‑GW development runway. Consensus forecasts show 2025 sales/FFO growth of ~8.3%/1.7% for O versus ~9.0%/9.5% for DLR, estimate revisions have been firmer for DLR, and YTD price performance has O +6.1% and DLR -10% (both lagging the S&P 500); O trades at a forward P/FFO of ~12.8x, DLR ~20.3x, and both carry weak value scores but different risk profiles. For investors prioritizing total upside tied to secular AI and cloud trends, Zacks favors DLR (Rank #2) while investors prioritizing stable income and capital preservation will find O’s predictability (Rank #3) more attractive, though DLR’s capital intensity and hyperscaler cycle exposure and O’s retail concentration and competition from private capital remain material risks.

Analysis

The article frames a clear bifurcation between defensive net-lease real estate and growth-oriented digital infrastructure, using Realty Income (O) and Digital Realty (DLR) as exemplars. Realty Income operates ~15,500 properties across 92 industries with typical occupancy near 98–99%, reported healthy Q3 2025 revenue growth, and a monthly dividend increased 133 times since listing; Zacks projects 2025 sales growth of 8.26% and FFO/shr growth of 1.67% with a forward P/FFO of 12.84X and a Value Score of D.

Realty Income’s strengths are stability, diversified essential-tenant cash flows and disciplined underwriting, but growth is limited by competition from private capital, retail-credit exposure, and muted FFO upside near term. These factors preserve capital-return reliability but constrain capital appreciation relative to secular growth sectors.

Digital Realty posted Q3 2025 revenue +10%, FFO/shr +13%, record interconnection bookings, a backlog >$850m and a 5‑GW development runway; more than 50% of quarterly bookings have been AI-related since mid‑2023. Zacks shows ~8.98% sales and 9.54% FFO/shr growth for DLR in 2025, a forward P/FFO of 20.26X (below its three‑year median) and a Zacks Rank #2, but the business remains capital‑intensive and exposed to hyperscaler spend cycles.

Relative valuation and recent estimate revisions favor DLR for upside tied to AI/cloud secular trends, while O remains the preferred choice for income and downside protection.

Key Decisions for Investors

• Consider overweight exposure to Digital Realty to capture AI/cloud secular upside given its record bookings, >$850m backlog and 5‑GW pipeline, but size positions to account for capital intensity and hyperscaler cyclicality
• Maintain or accumulate Realty Income for income-oriented allocations because of 98–99% occupancy, broad diversification across 15,500 properties and a long track record of monthly dividends, while accepting more modest capital appreciation
• Monitor near‑term indicators—DLR interconnection/bookings momentum and FFO revision trends, O tenant credit metrics and acquisition yield spreads—and use valuation gaps (both carry Value Score D) to trim, add, or hedge positions
