South Korean Police Investigate Polymarket Users for Illegal Gambling
The Gangwon Provincial Police Agency of South Korea has officially launched a criminal investigation into domestic Polymarket users at the request of the National Police Agency. This marks the first law enforcement action against prediction market users in South Korea, primarily involving bets related to the local elections on June 3, with user gambling amounts exceeding $52 million.
The Korea Communications Standards Commission had previously initiated a review, determining that Polymarket may constitute illegal gambling; the platform launched a local election market in South Korea and provided a Korean interface, which is seen as actively attracting local users. The police are currently focusing on investigating user betting behavior nationwide.
This move highlights the regulatory authorities' strict stance on cross-border prediction markets, with users potentially facing fines of up to 10 million KRW. The incident may impact Polymarket's expansion strategy in Asia and prompt the platform to adjust its compliance measures.

Polymarket has previously launched several Korean election markets, including the 2026 local election party victories and the Seoul mayoral election, with significant trading volumes, continuing its global event-driven prediction model, having built a user base and liquidity in markets like the U.S. elections.
In terms of capital flow, Polymarket quickly attracted Asian user funds through its Korean interface and local election markets, but faces risks of user asset freezes or exits following regulatory triggers, forcing the platform to balance growth with compliance costs during expansion, while directing capital towards more favorable jurisdictions or decentralized mechanisms.
This is similar to previous regulatory actions in multiple countries regarding prediction markets or crypto gambling, such as the historical reviews by the U.S. CFTC and bans in some European regions; currently, Polymarket is transitioning in the Asian market from user growth to regulatory control.
Essentially, this reflects regulatory changes: geopolitical regulators are strengthening scrutiny of cross-border prediction platforms based on gambling laws, reconstructing industry compliance thresholds through criminal investigations targeting users rather than platforms, concentrating pricing power among platforms with strong local licenses, geographic isolation, or decentralized designs, while raising barriers to entry in emerging markets and accelerating capital flow towards regulatory arbitrage areas.

Regulators first target users, then control platforms: whoever is seen as the traffic entry point becomes the target first.
Localization amplifies risk: the more convenient for local users, the quicker local legal switches are triggered.
Prediction markets are not neutral: high liquidity attracts high attention; the faster the growth, the heavier the regulatory hammer.
