Brazil: Chamber of Deputies passed urgency request for Bill on systemic relevance in digital markets and creation of the Superintendence of Digital Markets (PL 4675/2025) including unilateral conduct regulation

On 18 March 2026, the urgency request for the Bill on systemic relevance in digital markets and creation of the Superintendence of Digital Markets (PL 4675/2025), including unilateral conduct regulation was passed by the Chamber of Deputies. The Bill will now bypass thematic committee analysis and go to a plenary vote in the Chamber under a compressed timeline. 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.
