MCG in the Media: Digital Platforms in Brazil - the New Rules That Arrived Silently

  • June 29, 2026

Marco Antônio Junqueira de Arantes authors an article in Migalhas on one of the most relevant regulatory topics of the moment: the STF judgment on Article 19 of the Marco Civil da Internet and its impacts on digital platforms and foreign investors operating in Brazil.

With the perspective of someone who works daily on structuring foreign operations in the country, Marco analyzes the innovations and contradictions brought by the thesis established by the Supreme Court. The article highlights an aspect that went unnoticed amid the World Cup: the unprecedented requirement that the legal representative of digital platforms must necessarily be a legal entity with registered offices in Brazil.

Marco also contextualizes the requirement for foreign platforms to be headquartered in Brazil, something that was until now restricted to highly regulated sectors such as telecommunications, insurance and banking and the practical challenges this obligation imposes on internet application providers.

Essential reading for companies, lawyers and professionals operating in the Brazilian digital environment who need to understand what has really changed and what is still to come.
