Prologis is a publicly traded industrial real estate investment trust that owns, operates and develops logistics facilities across four continents. Founded in 1983 as AMB Property Corporation and operating under its current name following an $8.7 billion merger with ProLogis in 2011, the company focuses on high-barrier, high-growth markets where land constraints and proximity to large consumer populations drive demand for warehouse space. The REIT maintains a portfolio of approximately 1.3 billion square feet across 20 countries, serving around 6,500 customers primarily in business-to-business and retail/online fulfillment categories. Prologis employs a capital-light model, managing properties both on a wholly owned basis and through co-investment ventures with institutional partners. The company expanded through major acquisitions including DCT Industrial Trust ($8.5 billion, 2018), Liberty Property Trust ($13 billion, 2020), Industrial Property Trust ($4 billion, 2020), and Duke Realty ($23 billion, 2022). Prologis trades on the New York Stock Exchange under ticker symbol PLD and is an S&P 500 component. The United States represents approximately 62% of total square footage, with the remainder distributed across Europe (19%), Asia (9%), and other Americas (10%). The company faces geographic concentration in U.S. markets including Southern California, the San Francisco Bay Area, and the Inland Empire. Major customers span transport, freight, consumer goods, food and beverage, and third-party logistics sectors, though specific tenant concentration metrics by percentage of net effective rent are not publicly disclosed in available sources. Prologis has established joint ventures with institutional investors including Norges Bank and operates listed vehicles such as Nippon Prologis REIT in Japan and FIBRA Prologis in Mexico.
