The title of the biggest real estate developer in Saudi Arabia is shared between massive state-backed giga-project entities and large publicly listed private corporations driving the nation's ambitious transformation. Among private enterprises, Dar Al Arkan is widely recognized as the largest publicly listed real estate developer in the Kingdom, boasting extensive portfolios of residential communities and luxury developments. On a monumental scale, state-backed entities and giga-project developers such as ROSHN (a major national housing developer powered by the Public Investment Fund), NEOM, Diriyah Company, and Jabal Omar Development Corporation manage master-planning efforts that dwarf traditional developers. These organizations are collectively reshaping Saudi Arabia's urban landscape by constructing entire smart cities, tourist destinations, and millions of residential units to support rapid population growth.
