South Korea's Financial Supervisory Service (FSS) has reported a notable increase in illegal gambling and unauthorized lottery activities during 2025. The supervisory agency highlighted concerns that the growing presence of unlicensed gambling platforms poses significant risks, including potential gambling addiction and financial harm to consumers. The FSS stressed that these illegal operations evade government regulation, undermining efforts to maintain a stable and lawful gambling environment. In response, the FSS urged stronger enforcement measures, including enhanced surveillance and stricter penalties, to curtail the spread of illicit gambling practices. The authority emphasized its commitment to protecting consumers and ensuring that gambling operations comply fully with existing laws and regulations. These developments underscore ongoing challenges in regulating the gambling sector in South Korea amid increasing digital and unauthorized betting services.
