After reviewing the weakness of the Sports Betting Industry in Korea, this study suggested ways to enhance the competitiveness of the Sports Betting Industry. After reviewing the Sports Betting Industry, This was not competitive due to low commerciality and risk of business interruption. And this was poorly managed due to the weak purchase upper limit system and the prevalence of illegal intermediation. The needless trust structure, which is not found in other gambling industries, has made it difficult to guarantee public interest in the process of entrustment as it has been controversial during the trustee selecting process. As a way to strengthen competitiveness of the Sports Betting Industry, there was a need to adjust the total amount of sales to provide room for absorbing the demand for Illegal Sports Gambling. And there was a need to introduce electronic authentication system and to give the Korea Sports Promotion Foundation the right to the issuance and the determination for enhance competitiveness of business. Since the study, if the trust structure and competitiveness of the Sports Betting Industry have been improved, so that the substantiality, public interest, and business competitiveness of the Sports Betting Industry in Korea have been strengthened, thereby it is expected the Sports Betting Industry in Korea will be absorbing the demand for Illegal Sports Gambling.
