South Korea charges 26 Polymarket users, blocks platform over illegal gambling
South Korean police charged 26 Polymarket users for illegal gambling and referred 18 of them to prosecutors. The cases involve 17.6 billion won ($12.7 million) in alleged bets. Authorities blocked local access to the CFTC-regulated platform last month after its media regulator ruled it offered illegal gambling. The enforcement action marks one of the largest moves against individual users of a federally registered prediction market by an overseas jurisdiction.
The charges land on users, not the platform, but the practical effect is identical: Polymarket's liquidity pool shrinks when traders fear arrest. Korean retail participants who supplied volume to global markets now face prosecution at home, even though the exchange itself holds CFTC registration in the United States. That gap between American federal blessing and local gambling law is not abstract for the accused; it is a potential criminal record.
Other Asia-Pacific regulators watching Seoul's handling of the $12.7 million case may follow with their own user-side actions rather than platform blocks alone. Traders everywhere must now weigh whether their domestic laws carve out an exception the CFTC does not. Polymarket gains no legal shelter from its U.S. designation when foreign police knock on individual doors. The case tests whether prediction markets can build global liquidity pools when national gambling codes treat each bettor as a criminal.
South Korea joins Brazil as the second overseas jurisdiction to move against Polymarket users in under two days, showing that CFTC registration does not shield the platform or its traders from local gambling laws abroad.
