Brazil Bans 27 Prediction Markets as Wisconsin Sues Polymarket and Kalshi Over Sports Contracts

by Editorial Team

Brazil blocks 27 prediction platforms over gambling laws, while Wisconsin sues Kalshi and Polymarket, and a U.S. soldier faces $400K insider trading charges.


Global Regulatory Crackdown Hits Prediction Markets

Brazil's Finance Ministry has implemented a sweeping ban against 27 prediction market platforms, citing rising gambling addiction and investor protection concerns. As reported by Decrypt, the new rules classify many of these contracts as gambling, effectively blocking major platforms like Kalshi and Polymarket from operating in the country.

The regulatory pushback extends to the United States, where Wisconsin has launched a lawsuit against Kalshi, Polymarket, Robinhood, Coinbase, and Crypto.com. According to Cointelegraph, the state alleges that sports betting products offered on these platforms violate Wisconsin's gambling laws. This deepens the ongoing battle between state gambling enforcers and federal regulators, highlighted by the U.S. Commodity Futures Trading Commission (CFTC) suing New York and other states to prevent them from curtailing prediction market activity as state-regulated gaming.

$400K Insider Trading Scandal Draws Presidential Ire

As traders analyze shifting regulatory landscapes on predictionmarketstools.com, the industry is also grappling with a high-profile insider trading scandal. A U.S. soldier has been arrested and charged with using classified military intelligence to place a $400,000 insider bet on a "Maduro Raid" via Polymarket.

Interestingly, the soldier was forced to use Polymarket only after failing to pass Kalshi's Know Your Customer (KYC) procedures. The incident prompted U.S. President Donald Trump to remark that the world is becoming a "casino," stating he "was never much in favor" of prediction markets due to the exact risks highlighted by this intelligence breach.
