The digital transformation has shifted power in the European Union, giving dominant platforms unprecedented authority—termed Digital Power—that goes beyond traditional market dominance. These gatekeepers act as private legislators, controlling public discourse and infrastructure through algorithms and vast ecosystems, posing systemic threats to EU values and fundamental rights. Existing legal tools—the ex-post art. 102 TFEU and ex-ante DMA and DSA—are insufficient to address the constitutional challenges of this power, focusing mainly on economic effects rather than democratic and individual liberties. This paper argues for the direct horizontal application of the CFR, imposing constitutional duties on private digital actors with de facto regulatory power. By integrating fundamental rights into platform oversight, the approach extends the notion of ‘abuse’ beyond economic harm, proposing a legal framework that aligns competition law, structural regulation, and constitutional values to address Digital Power effectively.
