The Digital Markets Act (DMA) aims to make digital markets fairer and more contestable, and to provide new opportunities for startups and investors in the EU. Eoghan O’Neill, Senior Policy Officer in the Platforms Policy and Enforcement Directorate of the European Commission presents the new DMA obligations for the world’s largest digital platforms. He outlines how these obligations may translate into opportunities for startups and investors. Amongst other features of the DMA, he examines the DMA’s implications for the interoperability of messaging apps, third party app stores, and how it empowers users to take advantage of data portability.
