Why Argentina is blocking Polymarket despite global growth, focusing on gambling laws, user protection concerns and regulatory pressure on prediction markets. Argentina’s nationwide ban on Polymarket shows that rapid global growth does not shield platforms from local regulation, especially when their core activity resembles unlicensed gambling. Authorities applied an “economic reality” approach, focusing on user behavior rather than the technology, and concluded that staking money on uncertain outcomes aligns with traditional definitions of gambling.

Lawmakers are pushing new regulation for prediction markets after suspiciously timed Polymarket bets on US and Israeli strikes on Iran raised insider-trading concerns. Prediction market platforms Kalshi and Polymarket are reportedly exploring new fundraising rounds that could value the companies at around $20 billion each, roughly double their most recent valuations.

The judge found that the CEA’s savings clause does not completely displace state authority and that the companies had not shown a basis to block Nevada’s action at this stage. Read more
