Brief history

Created in June of 2001 by the then Bovespa, Câmara do Mercado, at the time called Câmara de Arbitragem do Mercado, offers a specialized and quick forum for the settlement of disputes, particularly those arising from the application of corporate and capital markets laws.

The Chamber's primary objective is to manage conflicts arising within the scope of companies committed to the adoption of differentiated corporate governance and transparency practices, listed at B3 in their special listing segments (Novo Mercado, Nível 2 of Corporate Governance, Bovespa Mais and Bovespa Mais Nível 2).

In addition, the Chamber has always been available for the management of any other disputes between individuals and companies, as long as they are related to business law.
