ARTICLE 19, as part of a coalition of civil society organisations, submitted a joint contribution to the European Commission’s consultation on competition and generative AI. In the submission, we highlight the challenges of regulating a sector where power is already concentrated, barriers to entry are high, and where a range of existing and potential anti-competitive practices threaten to undermine innovation, openness and fairness. We also draw attention to a number of specific issues that we believe the European Commission should focus its efforts on and recommend, among others, to create a new market investigation tool, upgrade the Digital Markets Act, investigate anti-competitive partnerships, and introduce a legal presumption against acquisitions by dominant firms.
