This paper discusses several issues related to the Digital Markets Act, the main document of the European Commission proposing a new approach to public policies in digital markets. We address three related issues. First, we discuss the relationship between the Dma, its tools and procedures, and the competition policy enforcement. Then we move to the sources of concentration in digital markets and the impact that the Dma may have on them by promoting competition in and for the market. Third, we conclude our analysis by looking at the emerging features of the new web, driven by the 5G revolution and the diffusion of the Internet of Things, discussing how and to what extent the Dma may be able to adapt to these changes.
