Data Centre REITs Outperform Broader Market with 22% YTD Returns

Publicly traded data centre real estate investment trusts have delivered exceptional returns in the first quarter of 2026, with the sector generating a weighted average total return of 22% year-to-date - significantly outpacing the S&P 500's 8% gain over the same period. The performance reflects investor confidence in sustained demand growth driven by artificial intelligence infrastructure spending, and positions data centre REITs as the best-performing real estate subsector for the third consecutive year.

Equinix, the sector's largest operator with a market capitalisation now exceeding $95 billion (making it the most valuable REIT of any type globally), reported same-store revenue growth of 11% in Q1 - its strongest quarterly performance in over a decade. The company's interconnection revenue, which carries significantly higher margins than colocation, grew 15% year-over-year as enterprises increasingly deploy hybrid cloud architectures that require direct connectivity between on-premises infrastructure and public cloud platforms. Equinix operates over 270 data centres across 75 metropolitan areas on five continents, serving more than 10,000 customers.

Digital Realty, which has pivoted aggressively toward hyperscale leasing under CEO Andy Power's strategy, signed a record 340 MW of new leases in the quarter with an average lease term of 12 years. The company's PlatformDIGITAL ecosystem, which enables tenants to deploy across multiple facilities globally through a single contract, has become a key competitive differentiator in winning hyperscale deals. Digital Realty operates over 300 data centres across 50+ metropolitan areas, with particular strength in the FLAP-D European markets and an expanding Asia-Pacific footprint.

Beyond the public REITs, the private market has been even more active. Private equity investment in US data centres reached $45.7 billion in 2025 - a five-year high that accounted for 72% of total US data centre investment per S&P Global. The $40 billion Aligned Data Centers acquisition by a consortium including Microsoft, NVIDIA, and BlackRock set a new record for the largest infrastructure transaction globally. Blackstone, which acquired QTS for $10 billion in 2022, is now reportedly considering a $2 billion IPO for its data centre platform - a move that would create yet another publicly traded pure-play.

Valuation metrics have expanded significantly. Equinix trades at approximately 30x forward funds from operations (FFO), compared to the traditional REIT average of 15-18x. Digital Realty trades at 25x forward FFO. These premiums reflect the market's conviction that data centre demand is structurally different from other real estate sectors - specifically that AI-driven growth provides a multi-decade demand tailwind that office, retail, and residential REITs lack. The premium also reflects the high barriers to entry (power infrastructure, fibre connectivity, and regulatory approvals create significant moats) and the recurring revenue nature of long-term colocation contracts.

However, some analysts have raised caution flags. If AI adoption follows a traditional technology S-curve rather than the linear growth currently priced into valuations, the sector could face overcapacity in the late 2020s as the massive construction pipeline delivers. Power grid constraints, which currently benefit existing operators by limiting new supply, could ease as utility investment programmes deliver additional capacity. And rising interest rates, while less of a factor than in 2023-2024, continue to weigh on leveraged REIT structures.

For investors, the data centre REIT sector offers a rare combination of growth and stability in real estate. The infrastructure-like characteristics of data centres (long-term contracts, creditworthy tenants, essential service nature) provide downside protection, while the AI demand driver offers upside exposure to the fastest-growing segment of the global economy. Whether current valuations are justified depends entirely on one's view of AI adoption curves and the sustainability of hyperscaler capital expenditure - which at $280 billion for 2026, shows no sign of abating.
