Kim Young-shub

Kim Young-shub leads KT Corp, South Korea's largest telecommunications company and one of the country's most important technology infrastructure providers. Formerly known as Korea Telecom, KT operates the nation's largest fixed-line broadband network (serving 9+ million subscribers with fiber-to-the-home), the second-largest mobile network (22+ million subscribers), and the country's largest IPTV platform. South Korea has some of the world's highest broadband penetration and speeds, making KT a provider in one of the most demanding telecom markets globally. KT has been aggressively positioning itself as an AI and digital platform company, moving beyond traditional telecom. The company has developed Korean-language large language models (branded as "Mi:deum"), built a cloud computing business targeting enterprise customers, and invested in AI-powered services across customer service, network optimization, and smart city infrastructure. KT's AI strategy leverages its unique position: it has massive amounts of Korean-language data from its telecom and IPTV operations, giving it a potential advantage in training Korean-specific AI models. Despite the AI pivot, telecom remains the revenue backbone. Key stock drivers include mobile subscriber trends, 5G monetization, ARPU trends, AI and cloud revenue growth, IPTV and content strategy, fiber broadband investment returns, competition with SK Telecom and LG Uplus, and the South Korean government's digital infrastructure policies.
