Brazil Antitrust Watchdog Opens Probe Into Microsoft's Cloud Licensing
Brazil’s competition authority has launched an administrative inquiry into Microsoft’s local operations to examine whether software licensing and cloud practices are disadvantaging rivals and customers. The early-stage probe could reshape how major cloud providers contract with Brazilian enterprises and public bodies if regulators find evidence of anticompetitive conduct.
On Jan. 2, 2026, the Administrative Council for Economic Defense (Conselho Administrativo de Defesa Econômica, CADE) opened an administrative inquiry into Microsoft’s Brazilian unit to investigate the company’s software-licensing and cloud-computing practices. CADE said its technical office recommended the formal inquiry and that Microsoft has been summoned to provide comments on the facts described in the regulator’s file.
CADE said the investigation will focus on whether Microsoft’s licensing terms and cloud policies are being used to influence the conditions under which cloud products are consumed and offered in Brazil. The regulator flagged “indications” that Microsoft may be leveraging a dominant market position to create barriers for competitors, and that the practices under review could stem from Microsoft’s global policies rather than arrangements designed specifically for Brazil.
Legal authorities will examine whether the conduct, if proven, amounts to unlawful competition or violations of the so-called economic order under Brazilian antitrust law. CADE said it will assess allegations including potential anticompetitive tying, discriminatory licensing terms and other contractual or technical measures that could distort competition in Brazil’s cloud market. At this stage CADE is gathering information and has not reached any findings of liability.
The probe arrives amid heightened global scrutiny of large cloud providers and how their licensing models affect markets, switching costs and customers’ freedom to choose alternative services. For Brazilian businesses and public institutions that rely on cloud infrastructure and productivity software, the inquiry raises questions about contractual flexibility, pricing transparency and dependence on a small number of dominant suppliers.
Microsoft has been formally summoned to respond to CADE’s allegations and to submit documents and explanations. The company’s response has not been disclosed publicly, and CADE has not set a timetable for later procedural steps or for issuing a final decision. No fines, remedies or corrective measures have been announced.
Available reporting does not identify specific complainants or provide detailed examples of the contractual clauses or practices that prompted the inquiry. That gap leaves open key lines of investigation for CADE, including whether particular customer contracts, product bundling, technical dependencies or migration restrictions are implicated and whether these effects are the result of coordinated global policy or local market conduct.
Competition-law experts say the inquiry could have consequences beyond any single case if it leads to new enforcement guidance or remedies that affect standard cloud-contract terms and licensing structures. For now, the matter is an early-stage regulatory review focused on fact-finding. CADE’s decision to open the inquiry signals that Brazil’s antitrust authority is prepared to scrutinize how global cloud providers structure their commercial relationships in a market of growing strategic importance.
