As a subsidiary of Dubai Inc., it is the emirate's flag bearer in global investments and has a central role in the direction of Dubai's economy. Assets include DP World, which caused considerable controversy when trying to take over six US ports, its property arm, Nakheel, which built The Palm Islands and The World developments, and Istithmar World, its investment company.

DP World is an Emirati multinational logistics company based in Dubai, United Arab Emirates. It specialises in cargo logistics, port terminal operations, maritime services and free trade zones. Formed in 2005 by the merger of Dubai Ports Authority and Dubai Ports International, DP World handles 70 million containers that are brought in by around 70,000 vessels annually. This equates to roughly 10% of global container traffic accounted for by their 82 marine and inland terminals present in over 40 countries. Until 2016, DP World was primarily a global port operator, and since then, it has acquired other companies up and down the value chain.
