Interim CADE president says innovation remains welcome but growing concerns over digital platforms’ market dominance justify stronger oversight
The new interim president of Brazil’s antitrust watchdog, the Administrative Council for Economic Defense (CADE), Diogo Thomson, has witnessed cartels evolve from arrangements coordinated through emails to practices involving algorithms. Elevated to the agency’s top position as the most senior member of CADE’s tribunal, Thomson is also a long-serving official at the institution, where he first worked as a federal prosecutor in 2007. He later served as deputy superintendent for ten years and as acting superintendent-general in 2017 and again between 2021 and 2022.
As president, Thomson has played a significant role in recent cases involving big tech companies and artificial intelligence, working in parallel with international antitrust authorities. In recent decisions, the agency required notification of transactions involving major technology companies and artificial intelligence firms for closer review. It opened an investigation into the use of news content by an AI tool.
Through June, Thomson said his focus will be on reforming CADE’s internal rules and on the proposed “Big Tech Bill.” Fast-tracked in the Lower House, Bill 4,675/2025 focuses on competition rules and market power and could significantly expand CADE’s authority. While waiting for the legislation, the regulator intends to address big tech issues using its existing powers, he told Valor. Below are excerpts from the interview.
Presidency
Being in an interim role creates the challenge of not knowing how long it will last. My advantage is that I have been here for a long time and know the institution well. The idea is to work in stages. Right now, we are dealing with what is urgent. We have a short-term plan through June. Then, because there will be the World Cup and elections, we have a second phase from June until the elections. After that, we need to understand what the government will look like and what the prospects are. For now, the idea is to address urgent matters and then see what is possible.
Priorities
Some issues have been on the agenda for some time, such as reforms to our internal rules, many of which are requested by companies and lawyers. One issue is a priority, though not necessarily urgent because it does not depend on us: the report on Bill 4,675 of 2025, which deals with digital markets and grants new powers to CADE. Because the bill is under an expedited legislative process, the rapporteur has until June to present a report. We will do everything within CADE’s reach to contribute to that process.
Big Tech Bill
There are challenges associated with the new responsibilities. If the bill passes, CADE will need a period of adaptation. The model envisions a new structure, and internally we can prepare the agency administratively within our capabilities. That includes rethinking our departments’ structure and working with the Ministry of Management to hire additional staff. CADE already has institutional expertise dedicated to studying digital markets, which can be put to good use once the bill is approved.
Revenue thresholds
Updating revenue thresholds is a longstanding request from companies, since they have never been adjusted. Inflation alone has created a significant gap relative to the current mandatory notification thresholds for merger filings [currently transactions involving one company with annual gross revenue of at least R$750 million and another with at least R$75 million]. Updating these thresholds would reduce the number of filings and improve efficiency. Both the Finance Ministry and the Justice Ministry have been paying close attention to this issue. We have been working with them on the best way to make the adjustment, which cannot be limited to notification thresholds alone. It must also include procedural fees, because CADE’s budget depends heavily on them.
Quorum
We need a quorum of four commissioners to open a hearing and three to issue rulings. My recusals—stemming from cases I worked on while serving in CADE’s technical staff before joining the tribunal—are becoming increasingly rare. I still have recusals involving some very old cartel cases that have been in the Superintendent-General’s Office for a long time. There are also some older cases related to the anti-corruption task force Car Wash, though not all of them. A reduced tribunal creates other challenges, particularly because commissioners don’t work with large teams. One of our short-term priorities is strengthening those teams. We also want to better organize hearing agendas so we can decide multiple cases at once. We recently did that with cases involving acquisitions of artificial intelligence companies by big tech firms.
Big tech companies
Our idea is to deal with big tech using the tools we already have to address problematic conduct. We are not enemies of innovation. On the contrary, we recognize that many of these companies bring innovative products. But there is concern about the power these companies hold, especially when they prevent new entrants or reduce user choice. That is one reason there is a legislative initiative to give CADE more authority. In the meantime, we will act within the scope of what we can assess under existing conduct investigations, just as we would in any other market.
Labor market
There is more than one case under review by the Superintendent-General’s Office that involves possible coordination in labor markets. Antitrust law has always dealt with these issues in some way. Labor is a cost and an input. If it is affected by anticompetitive conduct, it must be investigated. These cases involve different situations, from wage-fixing arrangements—which are equivalent to cartels because they fix an economic variable—to harder-to-prove cases, such as information exchanges that may affect labor markets. If companies coordinate or share information, they can exert pressure on workers, and the result may be lower wages. Another serious practice is agreeing not to hire competitors’ employees. That also reduces competition in labor markets. Our analysis does not focus on employment relationships. It focuses on the impact anticompetitive conduct can have on labor as an economic input.
Fuel market
The issue involving gas stations is closely related to the structure of Brazil’s fuel market. The retail segment is where competition is almost entirely free of regulation, which is why so many cases arise there. Fuel is also a homogeneous product, meaning prices tend to be very similar, which naturally creates suspicions of cartel behavior.
Aviation
CADE recently approved the deal between Azul and United Airlines, while the transaction between Azul and American Airlines remains under review by the Superintendent-General’s Office. In the case of United, there was a smaller ownership stake in Azul, making it less problematic from a competition perspective. In the case of American, a more careful analysis may be necessary regarding this type of cross-shareholding.
Master and BRB
The transaction involving Banco Master and Banco de Brasília (BRB) was reviewed by the Superintendent-General’s Office long before the issue became widely publicized. It followed the normal merger-review process. The banking market, particularly among smaller banks, generally does not present major competition concerns. From a competition standpoint, there were no significant issues. The Central Bank examined the broader systemic-risk concerns and reached its own conclusions. At CADE, the case never even reached the tribunal.
