backOn March 4, 2026, Brazil’s Administrative Council for Economic Defense (Cade) unanimously rejected an appeal filed by Meta and upheld an interim measure suspending the application of new WhatsApp terms of service in Brazil. The decision temporarily preserves the platform’s previous operating framework, allowing third-party artificial intelligence providers to continue offering chatbot services through WhatsApp Business Solution while the authority conducts an investigation into potential antitrust violations.
The administrative inquiry seeks to determine whether Meta may have leveraged its dominant position in the instant messaging market to favor its own artificial intelligence solution and restrict competing providers. According to Cade, the revised terms could potentially result in market foreclosure for rival AI service providers. The ruling requires WhatsApp to implement mechanisms enabling previously excluded chatbots to resume their operations, while the investigation continues to assess the merits of the alleged conduct.
