This commentary explores Brazil's role in Latin American platform capitalism, integrating Ruy Mauro Marini's theoretical framework with contemporary studies of platform capitalism. It examines the connections between Latin American platforms, overexploitation, and data accumulation, leading to the concept of platform sub-imperialism. Platform sub-imperialism refers to the emergence of certain Southern countries, such as Brazil, as platform sub-imperialist powers, acting as regional centers of data and capital accumulation through the expansion of their platforms into neighboring countries. This phenomenon constitutes an intermediate state between hegemonic nations and "digital colonies" in the international division of platform labor, data accumulation, and technological dependency. The article challenges the traditional view of all Global South countries as mere consumers and providers of raw data for platforms from the Global North. Instead, it argues that while some Latin American countries remain economically and technologically dependent on the North, they have developed their own platforms, and the expansion of these platforms into neighboring countries reproduces similar power dynamics among Southern countries. The focus is on Brazil and its leading labor platform, iFood, which has become the largest delivery platform in Latin America, organizing 250,000 workers and contributing to the development of artificial intelligence solutions. The article also discusses the historical conditions shaping platform capitalism in Latin America, particularly Brazil's role as a sub-imperialist power. It highlights how Brazil has leveraged its digital infrastructure, regulatory framework, and skilled workforce to lead investments in big data and drive the development of platforms in the region. The success of sub-imperialist platforms like iFood in organizing overexploitation allows them to compete effectively in these sectors with platforms from the North, reinforcing Brazil's position as a hub for data and capital accumulation. In conclusion, the article emphasizes the complexity of the Latin American political debate on the platform economy, where without a classist and plurinational approach, nationalist policies can justify the financing of national platforms based on overexploitation and strengthen platform sub-imperialism.This commentary explores Brazil's role in Latin American platform capitalism, integrating Ruy Mauro Marini's theoretical framework with contemporary studies of platform capitalism.
