Brazil just shut down access to prediction market platforms like Polymarket and Kalshi, saying they violate the country's betting regulations. Finance Minister Dario Durigan framed it as a consumer protection move, arguing these unregulated platforms pose real financial risks to everyday Brazilians. Brazil's central bank backed this up by banning derivatives tied to sports, politics, and similar outcomes.

Brazil isn't alone here—this is part of a broader global crackdown. Portugal blocked Polymarket earlier this year, for example, while multiple U.S. states have taken aim as well, with Wisconsin filing lawsuits against Kalshi, Robinhood, and others over sports betting contracts just this week.
