Brazil’s Superior Electoral Court (TSE) and the Attorney General’s Office (AGU) have formalized a cooperation agreement to issue binding guidelines for the use of Artificial Intelligence in the 2026 general elections, immediately raising the regulatory compliance risk for all major digital platforms operating in the country. The central tenet of the forthcoming guide is the mandatory requirement for all AI-generated content used in political campaigns to be explicitly identified, a directive that shifts the burden of technical enforcement and legal liability onto tech companies. This mandate, coupled with the TSE’s August 16 deadline for platforms with over five million active users to submit detailed electoral compliance plans, signals a clear market alert regarding increased operational costs and exposure for global and local internet-facing firms.
