The probe is being handled by the Gangwon Provincial Police Agency after a request from the National Police Agency. According to the local media, the investigation covers users throughout the nation, including those who live in Gangwon Province.
Election Markets Draw Police Attention
The trigger appears to be election-related activity on Polymarket. During the June 3 local races, Korean political markets attracted large crypto-stablecoin volume, with reported wagers running into hundreds of billions of won.
The scale of this event has changed the tone of the issue. Prediction markets existed before the election process. Now, the authorities are examining whether ordinary users, rather than only the platform, can be pursued under gambling law.
Korean Gambling Rules Leave Little Room
Strict controls have been enforced by South Korea regarding legal wagering. The only authorised legal sport wagering is via Sports Toto, which operates under tight purchase limits, including a KRW100,000 online limit per program.
Police are looking at Article 246 of the Criminal Act. A standard gambling offence can carry a fine of up to KRW10 million. Habitual gambling is treated more seriously, with penalties that can include imprisonment or a higher fine.
However, the legal question is still new for prediction markets. Polymarket has event contracts and not the usual sportsbook interface. Members take a stake in an outcome and often use dollar-denominated stablecoins.
Access Gap Adds Pressure
One challenge faced involves accessibility. Users based locally have apparently been able to use Polymarket without the help of IP blockers. Polymarket also appeared not to impose separate restrictions on Korean users transacting with dollar-denominated stablecoins.
This presents a regulatory dilemma since regulation may be achieved through blocking the website or by following the flow of transactions through user wallets. The probe suggests that user-level enforcement may become part of the regulatory response.
The case also matters for affiliates, crypto media and prediction-market promoters. While election markets tend to attract traffic rather quickly, they remain a risky venture for certain nations.
User Case May Set the Market Signal
The outcome may boil down to the legal interpretation of user intentions, transaction history, and how much of a player’s activity there was. According to a lawyer defending some users, the elements of a gambling offence may be present, but the likely punishment is hard to predict because Korea has no clear precedent for Polymarket use.
Such a scenario is the biggest lesson from the market perspective. Besides debating the need to block prediction markets in South Korea, the country is raising the question whether its participants could be considered gamblers retrospectively.
Takeaways for the Market
The case should be read as an early enforcement test, not a finished policy model. If police move ahead with user cases, prediction platforms may face stronger pressure to geofence Korean traffic before major elections. If the cases stall, regulators may still push blocking and reporting tools. Either way, election-linked crypto betting has moved from a niche compliance issue into a visible public-enforcement problem.
