Platform Regulation: what can lawmakers learn from CADE’s recent actions?

Apple recently announced changes to its operating system (iOS) in Brazil, including new options allowing developers to distribute applications through alternative app stores and to use other payment processing systems within those environments. These changes resulted from intervention by Brazil’s Administrative Council for Economic Defense (CADE), through a cooperative dialogue with the company.

The case originated from a complaint filed by Mercado Livre, which alleged that Apple imposed excessive restrictions on developers within the iOS ecosystem by (i) preventing developers from offering goods or services outside Apple’s system through their iOS apps (anti-steering rules), and (ii) requiring developers to use exclusively Apple’s own payment processing system. CADE initiated an administrative proceeding, imposed interim measures based on a theory of harm, and ultimately resolved the case through a settlement agreement. In response to these competition concerns, Apple raised another critical issue that benefits all developers within its ecosystem: the restrictions enhance cybersecurity standards and data protection for users (both developers and end consumers). The case is therefore highly complex, involving trade-offs between expanding competition in the distribution of digital services, on the one hand, and ensuring cybersecurity and personal data protection, on the other.

Despite the complexity and sensitivity of the matter—which goes to the core of Apple’s business model and that of numerous technology companies connected to its ecosystem—the case was resolved within three years of Mercado Livre’s complaint, filed in December 2022. A decisive factor was the dialogue between CADE and Apple, which culminated, in 2025, in the execution of a Cease-and-Desist Commitment Agreement (Termo de Compromisso de Cessação – TCC). In Europe, the issue took longer to resolve, involving four years of a traditional antitrust investigation followed by an additional round of oversight under the Digital Markets Act (DMA), which lasted another year.

Another recent case involves Meta/WhatsApp, concerning new WhatsApp Business terms that could restrict the use of the platform by artificial intelligence chatbots competing with Meta AI. Announced in October 2025, the new terms led to a complaint filed in November of the same year, after which CADE’s General Superintendence (SG/CADE) initiated an inquiry and imposed interim measures in January 2026. In March 2026, CADE’s Tribunal unanimously upheld those measures. The case demonstrates that, even in a novel and technically sensitive area, CADE was able to respond within a matter of months.

Several factors help explain this new approach, which runs counter to the Brazilian Ministry of Finance's 2024 assessment that CADE had been relatively ineffective in addressing competition issues in digital markets. First, CADE has developed greater expertise as an increasing number of cases involving digital services have come before the authority, whether in merger review proceedings or in investigations of allegedly anticompetitive conduct. Second, similar practices had already been examined in other jurisdictions. Third, the General Superintendence's (SG) use of interim measures intensified and accelerated the substantive discussion of these issues. Through the appeals filed by Apple and Meta against the interim measures, the cases reached CADE's Tribunal at an early stage, enabling it to formulate a preliminary assessment and identify sufficient elements to outline potential settlement alternatives. In the Apple case, these early indications enabled the company, through a collaborative process, to submit a proposal for a Cease-and-Desist Commitment Agreement (Termo de Compromisso de Cessação – TCC), relaxing its rules in a manner that addressed the concerns raised by the Tribunal while preserving critical aspects of operational security.

At the same time, two bills currently under consideration in the Chamber of Deputies propose markedly different approaches to competition regulation in digital markets. On the one hand, Bill No. 2,768/2022, as reflected in the latest substitute bill presented by Representative Any Ortiz in May 2026, proposes maintaining an ex post enforcement model focused on conduct that has already occurred, combined with a "fast-track" procedure designed to encourage settlements such as the one reached in the Apple case. On the other hand, Bill No. 4,675/2025 proposes a model under which CADE would assume functions closer to those of a regulatory agency by establishing ex ante rules and obligations applicable to certain digital services offered by large platforms, before any potentially anticompetitive conduct takes place.

While this legislative debate continues in Congress, CADE has also advanced its regulatory framework by implementing institutional improvements based on its experience in digital markets. Most recently, it adopted CADE Resolution No. 38/2026, which establishes governance rules for consensual dispute resolution mechanisms, as well as procedural rules governing the payment and collection of fines, with the aim of providing greater legal certainty for settlement agreements. This initiative reflects the authority's commitment to negotiated solutions, which reduce litigation while allowing arrangements that reconcile competition policy with innovation.

Along the same lines, CADE intends to establish a specialized team to investigate technology companies, regardless of whether either legislative proposal is enacted, consistent with its broader institutional structure based on specialized divisions. Digital markets require technical expertise, institutional memory, familiarity with digital business models, effective screening capabilities, and speed in enforcement. The creation of a dedicated division, together with support from CADE's Department of Economic Studies (DEE), may provide an effective mechanism for ensuring both efficiency and high-quality analysis in this area.

The settlement reached in the Apple case, CADE's swift response in the Meta case, and the authority's ongoing institutional reorganization and regulatory initiatives suggest that the most effective, expeditious, and consensus-based approach to competition regulation in Brazil's digital markets lies within CADE itself, building on its own institutional experience and design. It is essential that these internal institutional improvements continue to be implemented, particularly in light of the uncertainty in Congress, where two bills proposing diametrically opposed approaches remain under consideration. It is still unclear whether CADE should be granted a broader regulatory mandate and, if so, what the appropriate scope of those new powers should be.

Sound regulation must be grounded in a careful assessment of which additional enforcement powers are truly necessary, when they should be exercised, and what safeguards should accompany them. At this stage, the most appropriate response to the challenges posed by digital platforms appears to be strengthening what already works, correcting what has proven ineffective, and resisting the temptation to fundamentally redesign a successful institution through the enactment of new legislation.
