South Korean police have opened an investigation into users of the cryptocurrency prediction platform Polymarket on suspicion of illegal gambling. The probe, confirmed by local authorities, targets individuals who placed bets on the platform, which allows users to wager on the outcomes of real-world events using digital tokens.
The Legal Questions Around Polymarket
Polymarket operates as a decentralized prediction market, where users buy and sell shares in event outcomes — from election results to weather patterns. While the platform describes itself as a forecasting tool, South Korean law draws a hard line. The country's Criminal Code and Special Act on Regulation of Gambling ban most forms of private betting, with exceptions only for state-sanctioned lotteries, horse racing, cycling, and a few other activities.
The investigation centers on whether Polymarket's structure amounts to illegal gambling. Police have not disclosed how many users are under scrutiny or the volume of funds involved. The platform is not registered with South Korean regulators, and its use of cryptocurrency makes transactions harder to track — something investigators are now trying to untangle.
Previous Scrutiny of Prediction Markets
Polymarket has faced regulatory questions elsewhere. In the United States, the Commodity Futures Trading Commission has targeted prediction markets in the past, arguing that some contracts function as unregistered gambling. The platform limits access from certain jurisdictions but has not publicly commented on the South Korean investigation.
South Korea's move is notable because the country has some of the world's strictest anti-gambling laws. Even friendly bets among acquaintances can be legally risky if they involve money. The rise of crypto-based betting platforms has complicated enforcement, as transactions can occur across borders without traditional banking oversight.
Police have not said whether charges have been filed or if arrests are imminent. The investigation is in its early stages, and legal experts expect authorities to focus on heavy users or those who may have profited significantly. South Korean law allows for fines and prison time for illegal gambling, with penalties increasing for organized or large-scale operations.
For now, the probe sends a warning to anyone using unregulated betting platforms in South Korea. The question that remains unanswered is how far police will go — and whether this marks the start of a wider crackdown on crypto prediction markets in the country.
