Which real estate company owns the most retail space in the United States?

The real estate company that owns the most retail space in the United States is Simon Property Group.

Simon is a publicly traded real estate investment trust headquartered in Indianapolis, Indiana. Its portfolio is concentrated in shopping malls, Premium Outlets, The Mills properties and lifestyle centers, giving it an unusually large footprint in consumer-facing retail real estate.

The company grew from the Simon brothers’ mall investments and went public as Simon Property Group in 1993. It later expanded through major acquisitions, including the 1998 purchase of Corporate Property Investors and its 2010 acquisition of Prime Outlets. Those deals helped make Simon the dominant U.S. mall owner and operator.

This question is easy to confuse with rankings for total real estate, industrial warehouses or brokerage services. Prologis is a logistics-property giant, CBRE is primarily a services and investment firm, and Blackstone owns many property types. Simon’s claim is specifically tied to retail real estate, especially large shopping destinations.
