Brazil Bans Kalshi and Polymarket in Major Prediction Market Crackdown
Brazil has imposed a sweeping ban on prediction markets and online betting platforms, including leading names Kalshi and Polymarket.
Why Brazil Blocked Prediction Markets
The Brazilian Central Bank (Banco Central do Brasil) issued a resolution prohibiting derivative contracts tied to sports events, political outcomes, entertainment, or any non-financial benchmarks.
Finance Minister Dario Durigan announced that 28 betting platforms have been blocked. The move aims to protect Brazilian investors and curb the rise of online gambling.
Platforms Now Inaccessible
Researchers confirmed that both Kalshi and Polymarket are no longer accessible from within Brazil. The platforms failed to meet local rules on derivatives trading, investor protection, and market integrity.
Key Details from the Ban
The resolution clearly states that contracts based on real or virtual events — such as elections, sports, or cultural happenings — are now illegal unless they represent genuine economic or financial benchmarks.
This decision forms part of a larger government effort to safeguard public savings amid growing concerns over unregulated online betting.
Global Challenges for Prediction Markets
Polymarket is already restricted in over 30 countries, including France, Belgium, Australia, the UK, Italy, Portugal, and Singapore. Many nations have banned political betting or specific event contracts.
In contrast, the United States has taken a more supportive stance. Kalshi won a legal battle against the CFTC in 2024, allowing prediction markets to operate more freely. However, some U.S. states like Wisconsin continue to challenge these platforms.
What This Means for Users
Brazilians can no longer access Kalshi or Polymarket due to the nationwide ban. The government’s focus remains on protecting citizens from potential financial risks associated with event-based betting.
This latest development highlights the growing divide between countries embracing prediction markets and those choosing strict regulation.
