Brazil, Bots, and the Price of Free
Brazil’s WhatsApp case began as a fight over access to an application programming interface, or API—the technical doorway that lets outside services connect to WhatsApp. It has quickly become a test of how antitrust law should treat AI distribution.
The Federal Court of São Paulo has now suspended the R$250,000, or about $50,000, daily fine that Brazil’s Administrative Council for Economic Defense (CADE) imposed on Meta in its WhatsApp AI-chatbots case, sending the parties into conciliation instead. The judicial decision remains under seal, but it marks the latest turn in a remarkable four-month saga.
CADE opened an administrative inquiry and imposed an interim measure. A federal court initially suspended that measure, then reinstated it after a closer look. CADE then imposed a daily fine after concluding that Meta had not adequately complied. Now, that fine has been paused, too.
The merits remain unresolved, making this a useful moment to ask what the dispute is really about—and where the harder questions lie.
The short version is that CADE’s dominance theory rests on relatively firm ground. Its theory of harm, by contrast, depends on assumptions about AI markets that the available evidence is unlikely to support. In that sense, the court’s decision to pause the fine and require conciliation may create a useful off-ramp in an important antitrust dispute.
