The report adds another front to global pressure on prediction markets, especially those tied to politics.

Analysis
What happened
South Korean police have reportedly launched the country’s first illegal gambling probe focused on local Polymarket users. According to the report, Gangwon Provincial Police is handling the investigation after a request from the National Police Agency.
The legal concern is straightforward: users could face fines of up to 10 million won, or about $6,500, under Article 246 of South Korea’s Criminal Act, which covers gambling and habitual gambling. The article also notes that Sports Toto is the state-authorized sports betting platform, while unauthorized online betting can be prosecuted under South Korean gambling laws.
Why Polymarket is under pressure
The probe fits into a broader crackdown on prediction markets. The story says several jurisdictions have blocked or restricted access to Polymarket, including Singapore, Poland, Portugal, Hungary, Ukraine, Brazil and Indonesia. Polymarket remains accessible in South Korea, but the reported investigation shows access alone does not eliminate legal risk.
The article also places the case in the context of political betting scrutiny. It mentions a Polymarket contract tied to whether Lee Jae-myung would be out as president of South Korea in 2026, which drew nearly $54,000 in total trading volume. More broadly, the piece says political betting has drawn criticism from lawmakers and regulators in the US as well.
Polymarket has responded to this pressure by considering a mandatory identity verification system more aligned with global KYC standards, according to the article. It also said it was geoblocked in 35 regions at the time of writing.
The key takeaway is that prediction markets are moving deeper into the regulatory crosshairs. Even where the platform is still accessible, users may face enforcement risk if local law treats the activity as gambling.
Key points
- South Korean police reportedly opened the country’s first illegal gambling probe into local Polymarket users.
- Gangwon Provincial Police is leading the case after a request from the National Police Agency.
- Users could face fines of up to 10 million won under South Korea’s gambling law.
- The report says Polymarket remains accessible in South Korea but is blocked or restricted in many other jurisdictions.
- The case adds to wider scrutiny of political betting and prediction markets.
If the scrutiny pushes Polymarket toward stronger identity checks and clearer compliance controls, it could reduce legal confusion around who can use the platform. That could make prediction markets easier for regulators to understand and potentially safer for users in some regions.
The probe could discourage users from participating and encourage more countries to block or restrict access to Polymarket. If authorities treat prediction-market activity as gambling, users may face fines or other enforcement even when the platform remains technically available.
