The biggest real estate companies in the world do more than buy, develop, and lease properties. They operate senior housing communities, manage logistics warehouses, provide space for AI computing infrastructure, and own shopping malls and commercial buildings. The global real estate market is projected to reach $624.62 trillion in 2026, according to Statista’s global real estate market outlook.
This list ranks the top real estate companies by market capitalization, which measures a publicly traded company’s total stock market value. Market capitalizations change with share prices, so the ranking and figures below reflect the latest available data.
These global real estate firms operate across healthcare, industrial logistics, data centers, telecommunications infrastructure, retail, self-storage, and commercial property. Many are real estate investment companies structured as real estate investment trusts (REITs).
What are REIT companies?
A Real Estate Investment Trust (REIT) owns, operates, or finances income-generating real estate. In the United States, REITs generally must distribute at least 90% of their taxable income to shareholders to qualify for the relevant federal tax treatment, subject to applicable requirements.
