Brazil's B3 stock exchange to launch bitcoin-linked 'event contracts'

Brazil's B3 stock exchange is set to introduce six new derivatives contracts, called Event Contracts, on April 27th. These contracts allow professional investors—those with at least 10 million reais ($1.9 million) in assets—to speculate on the probability of future events, including bitcoin price movements, dollar fluctuations, and changes in the Ibovespa index. The contracts are regulated by Brazil’s securities regulator (CVM) and function similarly to prediction markets like Kalshi and Polymarket, with prices reflecting market-estimated probabilities. Settlement is cash-based, and traders won’t take delivery of the underlying assets. This launch is part of B3’s broader effort to modernize derivatives trading and follows the exchange’s work on a tokenization platform and stablecoin. While B3’s launch is the first federally regulated prediction market in Brazil, it joins a growing field with existing platforms and international players like Kalshi and Polymarket.
