Brazil’s B3 to launch bitcoin-linked “Event Contracts” for ultra-rich investors
Brazil’s main stock exchange, B3, will roll out six new derivatives called Event Contracts on April 27, giving wealthy investors a regulated way to bet on future outcomes — from bitcoin prices to moves in the dollar and the Ibovespa index.
What they are
- Event Contracts work like prediction-market bets: each contract’s price (up to 100 reals, roughly $19) reflects the market’s estimated probability that a specified outcome will occur. Contracts have fixed payouts and known maximum losses from the outset, and are settled in cash — traders will not take delivery of underlying assets.
- The initial suite covers mini futures and spot-style contracts tied to the Ibovespa index, the U.S. dollar and bitcoin.
Who can trade
- B3 says the products are regulated by Brazil’s securities regulator (CVM) and are aimed at professional investors. Trading will be limited for now to investors with more than 10 million reals (about $1.9 million) in assets or those holding CVM certification.
Why it matters
- B3’s VP of Products and Clients, Luiz Masagão, framed the launch as part of a broader push to modernize Brazil’s derivatives market. The exchange has already introduced contracts linked to central bank decisions in several countries and has been watching the rise of predictive platforms overseas.
- The move signals institutional recognition of prediction-style instruments in Brazil: B3’s offering will be the country’s first federally regulated prediction market product, contrasting with domestic services such as Prévias and Palpitada that have operated in a regulatory gray area.
Crypto and broader strategy
- The bitcoin-linked contracts add a crypto-flavored option to B3’s derivatives lineup at a time when the exchange is also building new digital infrastructure: late last year B3 confirmed it is developing a tokenization platform and a stablecoin, both expected this year.
Global context
- Prediction markets are booming worldwide. A Dune dashboard shows notional volume approaching $160 billion and more than 3 million unique users. U.S. platforms Kalshi and Polymarket dominate volumes; Intercontinental Exchange (owner of the NYSE) has recently increased its investment in Polymarket to nearly $2 billion.
- Kalshi has also moved into the Brazilian market via a partnership with XP International, the country’s largest brokerage, to offer event contracts tied to Brazilian economic outcomes.
Regulatory uncertainty
- Despite federal regulation of B3’s new product, the broader legal framework for prediction markets in Brazil remains unsettled. Legal experts say it’s not yet clear whether oversight should rest with the CVM, the Central Bank or the Ministry of Finance — an ambiguity that could shape how quickly similar products multiply and who they will be available to.
What to watch
- Short term: participation rules and how liquid the contracts are once trading opens April 27.
- Medium term: whether B3 broadens access beyond high-net-worth and certified investors, and how its tokenization/stablecoin plans interact with these new markets.
- Regulatory developments will be critical: clarity from Brazilian authorities will determine whether prediction-style contracts become a mainstream institutional tool or stay a niche, high-net-worth product.
