In response to a complaint related to Polymarket, the Korea Communications Standards Commission has opened a review of the platform. The regulator will evaluate if the prediction market can be considered illegal gambling under South Korean law.
Korean Access Brings the Issue Onshore
One more issue the review addresses is whether Polymarket promotes gambling behavior. This aspect is crucial for enforcement since the platform does not operate as a regular online bookmaker.
Polymarket allows users to trade on the outcomes of different real-life events. Its markets can cover elections, interest rates, cryptocurrencies, and sports. Transactions are often made through stablecoins, and payouts are based on the results of events.
This means that although Polymarket appears to be similar to event trading, users place their funds at risk based on future outcomes. So, South Korea has to determine what category would apply here legally.
Local Language May Carry Legal Weight
Polymarket remains accessible in South Korea and offers a Korean-language interface. This aspect can be important for the review.
Servers may be hosted outside of South Korea. However, due to Korean-language support, the site might come under the regulator’s review. Moreover, the commission is now researching regulatory approaches of other countries dealing with the same issue.
The case shows how offshore platforms can still face local scrutiny when they offer local-language access. However, it looks like in South Korea, visible access and local targeting may be enough to trigger scrutiny.
Prediction Markets Face a Harder Line
The Korean review comes in the wake of rapid growth in prediction market activity. Bernstein data, quoted by Bloomingbit, put the figure for global trading at $51 billion in 2025. These figures were expected to be $240 billion in 2026 and reach $1 trillion in 2030.
Regulators in several jurisdictions have already moved to crack down on Polymarket. Countries including France, Germany, Italy, India, Brazil, Australia, and Argentina have classified Polymarket as an illegal gambling site and blocked access, according to Bloomingbit. In the US, state-level pressure has also increased, with Minnesota, Wisconsin, and Nevada pursuing bans, lawsuits, or enforcement actions tied to sports-event contracts on prediction-market platforms.
Blocking Remains on the Table
When speaking to Bloomingbit, Jin Hyun-soo, managing partner at Decent Law Firm, said that the commission could block access if Polymarket offers its service in the Korean language or targets Korean users. The platform also runs a high chance of being forced out of the market if it continues operating without engaging with local regulatory rules.
Final Notes
For South Korea, the decision will test the flexibility of gambling law in situations where crypto rails and market prices are involved. Prediction markets can no longer treat language, payment design, and server location as separate issues. A Korean-facing product may be judged by Korean rules, even if the company sits elsewhere.
