Brazil's main stock exchange, B3, will launch six new derivatives contracts on April 27 that allow investors to bet on future events, such as the price of bitcoin or movements in the dollar and Ibovespa index. The instruments, called Event Contracts, operate on a framework similar to prediction markets like Kalshi and Polymarket. The contracts are regulated by Brazil’s securities authority (CVM) and designed for professional investors. Only those with more than 10 million reals ($1.9 million) in assets or CVM certification can trade the new products. The launch is part of B3's broader push to modernize derivatives trading in Brazil.
