South Korea targets individual Polymarket users after $52M Seoul election market
South Korean police are investigating individual domestic users of Polymarket on suspicion of illegal gambling, not the platform itself. The enforcement action follows a Seoul election market that reached $52 million in volume. The decision to target bettors rather than the operator marks an unusual approach to offshore prediction market activity, according to the available reporting. Authorities have not disclosed how many users are under investigation or what specific charges they may face. The probe adds to Polymarket's growing legal exposure in Asia. The platform is CFTC-regulated through its acquisition of licensed exchange QCEX and operates in the US under an agency order of designation.
Polymarket traders in South Korea now face potential criminal gambling charges rather than civil regulatory penalties. Any convictions would give other Asian regulators a ready template for classifying prediction market trading as criminal gambling.
Polymarket faces parallel enforcement pressure on three fronts this year: South Korean criminal gambling charges against its users, DOJ insider-trading prosecution of a Google engineer exploiting search data on its markets, and four simultaneous state-level gambling lawsuits against rival Kalshi threatening to erode the federal preemption shield protecting all CFTC-designated platforms.
