Regulating Digital Gatekeepers – the Digital Markets Act

As digitalisation has increased and data has become more powerful, more comprehensive digital regulation has become necessary, including by national competition authorities and the European Commission. The Digital Markets Act (the DMA) is a good example of this area of regulation.1 In November 2022, the DMA came into force, introducing new regulations for core platform services which functioned as ‘gatekeepers’ in the digital market. By enacting the DMA, these platforms are prevented from treating businesses and consumers unfairly. The purpose of this paper is to provide a general overview of the DMA and its relationship to antitrust enforcement.
