Brazil's B3 Stock Exchange will launch six regulated event contracts on April 27, allowing professional investors to speculate on events such as Bitcoin prices, US dollar trends, and the Ibovespa index. These cash-settled derivative contracts will be priced up to 100 reais (approximately $19), similar to prediction markets like Kalshi and Polymarket, but participation is limited to assets exceeding 10 million reais (about $1.9 million) or investors holding certification from the Brazilian Securities and Exchange Commission (CVM). This marks the launch of Brazil's first federally regulated prediction market, entering a global prediction space with a nominal trading volume of nearly $160 billion.
