Valued at $73.1 billion by market cap, Digital Realty Trust, Inc. (DLR) is one of the world's largest data center real estate investment trusts (REITs), providing the critical infrastructure that powers cloud computing, artificial intelligence, enterprise IT, and digital connectivity. Headquartered in Austin, Texas, the company owns, develops, and operates a global portfolio of carrier-neutral data centers that enable businesses to securely store, process, and exchange data.
Despite sitting at the heart of the AI-driven data center boom, Digital Realty hasn't fully capitalized on the market's enthusiasm over the past year. DLR has gained 13.6% over this time frame, while the broader S&P 500 Index ($SPX) has rallied 21.5%. That said, the stock has staged an impressive comeback in 2026, climbing 24.5% year to date, nearly doubling the benchmark's 12.6% gain.
