Simon Property Group began in 1960, when brothers Melvin and Herbert Simon started building shopping centers in Indianapolis. The business grew into enclosed regional malls across the Midwest, co-developed Mall of America, and listed on the NYSE in a 1993 IPO as a real estate investment trust. A 1996 merger with DeBartolo Realty and the 2004 purchase of Chelsea Property Group, which brought the Premium Outlets brand, made it the largest U.S. mall owner.
Concentrating on the strongest centers
As e-commerce and department-store closures hurt weaker malls in the 2010s, Simon narrowed its focus. In 2014 it spun off 98 smaller malls and strip centers as Washington Prime Group, which later went bankrupt in 2021. Simon kept higher-productivity malls and outlets in major metros and tourist markets and spent heavily replacing vacant anchor stores with restaurants, fitness clubs, hotels and apartments.
Pandemic deals
In 2020 Simon tried to walk away from its agreement to buy Taubman Centers, then settled at a reduced $43 per share and acquired an 80% interest in Taubman Realty Group. It also partnered with Authentic Brands Group to buy bankrupt mall tenants through SPARC Group, which combined with JCPenney in January 2025 to form Catalyst Brands. In late 2025 Simon bought the remaining 12% of Taubman Realty Group.
Results and leadership in 2025-2026
Simon reported 2025 revenue of $6.365 billion and record Real Estate FFO of $4.8 billion, or $12.73 per share. After David Simon died in March 2026, his son Eli Simon became CEO. In Q2 2026 Real Estate FFO rose 7.9% to $3.29 per share, occupancy stayed at 96.0%, and the company raised 2026 guidance to $13.20-$13.30 per share.
