On 17 September 2025, the Bill on systemic relevance in digital markets and creation of the Superintendence of Digital Markets (PL 4675/2025) was introduced in the Chamber of Deputies. The Bill prohibits undertakings designated as of systemic relevance from engaging in unilateral conduct such as restricting competitors’ access to markets or adjacent markets, favouring their own services or products using data, tying the acquisition of products or services, limiting access to essential information, preventing business users from reaching final users directly, or applying predatory or abusive strategies. These prohibitions are subject to oversight and enforcement by the Superintendence of Digital Markets and the CADE Tribunal.
