CADE Members Back Proposal by Interim President Diogo Thomson de Andrade to Refer Case to Superintendent
Brazilian antitrust authorities have greenlit an intensified investigation into Google’s business practices, marking a significant escalation in the country’s scrutiny of Massive Tech dominance and setting the stage for potential structural remedies that could reshape digital market competition in Latin America’s largest economy.
The Administrative Council for Economic Defense (CADE) voted unanimously on April 22, 2026, to refer the case back to its superintendence for a deep-dive probe after interim president Diogo Thomson de Andrade’s proposal gained full board support. This decision revives a dormant inquiry initially triggered in 2021 over allegations that Google abused its dominance in online search and advertising to stifle competition, particularly disadvantaging local Brazilian publishers and ad tech firms. With the investigation now poised to examine not only historical conduct but as well current algorithmic preferences, data sharing practices, and Android ecosystem controls, the outcome could trigger fines exceeding 10% of Google’s global Brazilian revenue and mandate behavioral or structural changes.
This move arrives amid a broader global reckoning with tech monopolies, echoing parallel actions by the European Union’s Digital Markets Act and ongoing U.S. Department of Justice litigation. Yet Brazil’s approach is distinct: CADE has historically favored behavioral remedies over breakups, focusing instead on enforcing fair access, transparency in ad auctions, and non-discriminatory treatment of local content. The renewed scrutiny reflects growing concern that despite prior commitments, Google’s market share in Brazilian search remains above 90%, whereas its advertising platform continues to siphon disproportionate value from domestic media outlets struggling to monetize digital audiences.
Why This Investigation Matters for Brazil’s Digital Economy
Beyond the courtroom, the probe’s implications ripple through São Paulo’s tech corridors, Rio de Janeiro’s media houses, and Brasília’s policy circles. Local publishers, already reeling from declining print revenues, argue that Google’s search algorithms prioritize international news sources and its own properties, reducing visibility for Brazilian journalism. Ad tech startups in Belo Horizonte and Porto Alegre claim they face opaque bidding systems that favor Google’s ad exchange, making it nearly impossible to compete without surrendering data or paying premium access fees.
“When a single platform controls both the marketplace and the rules of the game, it’s not competition—it’s control,” said
Mariana Souza, senior researcher at the Institute for Technology and Society (ITS Rio),
explaining how algorithmic opacity undermines fair market participation. “Brazilian businesses aren’t asking for special treatment; they’re asking for the same transparency and non-discriminatory access that users in Europe or the U.S. Now legally expect under newer digital regulations.”
The investigation also touches on Android, where Google’s operating system powers over 80% of smartphones in Brazil. Critics allege that pre-installation agreements and revenue-sharing mandates effectively lock out alternative app stores and search providers, a concern amplified by the fact that over 60% of Brazilian internet users access the web primarily via mobile devices.
Historical Context: From 2021 Complaints to 2026 Action
The roots of this case trace back to a 2021 complaint filed by the Brazilian Association of Online Newspapers (ANJ) and the National Association of Publishers of Books (ANEL), which accused Google of leveraging its search dominance to force unfavorable terms on news publishers regarding content display and revenue sharing. Although CADE initially opened an administrative proceeding, it was suspended in 2022 pending the outcome of similar investigations in Europe.
Now, with the EU’s DMA imposing specific interoperability and fairness obligations on gatekeepers like Google, and with Brazil’s own legislative debates around a proposed “Digital Platforms Law” gaining traction, regulators appear emboldened to act. Legal experts note that CADE’s current approach may draw inspiration from the EU’s framework while adapting it to Brazil’s institutional realities—where proving abuse of dominance requires demonstrating actual harm to competition, not just market power.
“This isn’t about punishing success,” stated
João Silva, professor of antitrust law at FGV Law School in São Paulo,
“but about ensuring that dominance doesn’t translate into the power to exclude competitors or dictate terms that distort market outcomes. Brazil has waited long enough; the digital economy can’t afford another decade of unchecked gatekeeping.”
The Real-World Stakes: Who Bears the Cost?
If CADE ultimately finds Google in violation, the consequences could extend far beyond the company’s balance sheet. Brazilian advertisers—particularly compact and medium enterprises reliant on Google Ads for customer acquisition—may face short-term disruption if ad auction rules change abruptly. Yet many observe long-term gain: a more transparent system could lower customer acquisition costs and improve ROI by reducing fraud and increasing competition among ad networks.
Meanwhile, telecom providers and device manufacturers could benefit if remedies include loosening restrictions on alternative app stores or search defaults on Android devices. Municipal governments in cities like Curitiba and Recife, which have launched digital inclusion programs to expand internet access, may locate it easier to promote locally developed tools if users aren’t funneled exclusively toward Google’s ecosystem.
For consumers, the potential upside lies in greater choice: more diverse search results, reduced data concentration, and possibly lower prices for digital services if competition intensifies. However, any remedy must balance innovation incentives with fair access—a tension CADE will necessitate to navigate carefully to avoid undermining the very services users rely on.
Digital Infrastructure and Local Solutions
As this legal battle unfolds, Brazilian businesses and institutions aren’t waiting passively. In São Paulo’s Vila Olímpia district, law firms specializing in tech regulation are seeing increased retainers from media companies seeking counsel on compliance and potential damages. In Belo Horizonte, a growing cohort of ad tech startups is exploring alternatives to Google’s stack, investing in header bidding and private marketplace solutions that promise greater transparency.
These developments highlight a clear pattern: when platform power is questioned, the demand rises for specialized expertise that can support navigate regulatory shifts and build resilient, independent digital operations. Companies looking to audit their ad tech dependencies or assess exposure to platform policy changes are turning to technology and antitrust law firms with proven experience in Big Tech litigation. Simultaneously, organizations aiming to diversify their traffic sources or build owned-audience strategies are consulting independent performance marketing agencies unaffiliated with major platform ecosystems.
On the ground, municipal digital inclusion offices in Brasília and Fortaleza are partnering with community technology hubs to develop open-source tools and training programs that reduce reliance on proprietary platforms—efforts that could gain momentum if CADE’s investigation encourages broader ecosystem openness.
Brazil’s decision to reopen this case isn’t merely a legal formality—it’s a signal that emerging economies are no longer willing to accept digital colonialism by proxy. The outcome will shape not just Google’s obligations in one market, but potentially influence how other nations approach platform regulation in an era where data, attention, and algorithms are the new currencies of power. For businesses navigating this uncertainty, the path forward lies not in reacting to headlines, but in building relationships with advisors who understand both the law and the logic of the digital economy.
