The largest real estate owner in the world is typically categorized by institutional asset size rather than individual ownership, with major government bodies, sovereign entities, and massive asset management firms holding the vastest portfolios. For instance, the Catholic Church historically maintains massive global land holdings, while modern corporate giants like Brookfield Asset Management and institutional investment firms like Blackstone control hundreds of billions of dollars worth of commercial, industrial, and residential real estate globally. In terms of public logistics warehousing, Prologis commands a massive global footprint spanning thousands of distribution facilities across multiple continents, making it a dominant physical owner of commercial real estate infrastructure.
