During the Olympic/Paralympic cycle, Brazilian sport administration entities constantly struggle to obtain and maintain their sponsorships. This study aimed to survey the number and value of each sponsorship by COB and Confederations and CPB in the period 2014-2018, analyzing the evolution before and after the Rio 2016 Games. The study has a descriptive character, a quantitative approach, carried out through documentary research with data from the balance sheets of the entities. At the end of the period analyzed: COB lost three sponsorships after 2016, but gained another three, all-private; 70% of the NGBs had no sponsorship; CPB halved its sponsorships and amounts received. In the group of entities analyzed, there was a sharp drop in the number of sponsorships and, consequently, in the amounts contributed to the COB, CPB, and Confederations, especially after Rio 2016. It highlights the attention that should be given to a closer relationship between companies and sports entities.
