SK Telecom's SK Horizon Secures $2.3B for AI Data Centers

South Korean telecom giant SK Telecom has officially launched SK Horizon, a dedicated entity focused on AI data center infrastructure, backed by a substantial $2.3 billion (3.08 trillion won) investment. This strategic move carves out SK Broadband's data center operations into a new, independent company, positioning it to aggressively pursue the rapidly expanding AI computing market. The significant capital infusion comes from a consortium of prominent investors, including global private equity firm KKR, which is contributing a significant portion, alongside IMM Investment and Stonebridge Capital.

Under the new structure, SK Telecom will retain majority control with a 51% stake in SK Horizon, ensuring strategic alignment with its broader AI ambitions. KKR will hold a 29% share, while the IMM Investment-led consortium will own 20%. This governance framework is designed to empower SK Horizon with operational agility while leveraging the strategic direction of its parent company. The spin-off is expected to be finalized in the first quarter of next year, pending regulatory approvals and shareholder consent.

SK Horizon is set to manage and expand a significant portfolio of data center assets, encompassing 318 megawatts of capacity. This includes eight operational facilities across key South Korean locations and new AI data centers currently under development. A key strategic component of its expansion plan involves the phased development of submarine cable infrastructure, crucial for supporting global AI workloads and enhancing South Korea's digital connectivity. This focus on subsea cables underscores the company's ambition to be a critical node in international data flow.

The influx of capital will fuel SK Horizon's aggressive expansion plans, enabling the construction of additional AI-optimized data centers and the enhancement of its existing infrastructure. This initiative aligns with a broader trend of increased investment in digital infrastructure, driven by the insatiable demand for AI processing power. The global data center market is projected to grow substantially, with AI workloads being a primary catalyst. SK Horizon's strategic positioning in South Korea, a hub for technological innovation and digital adoption, provides a strong foundation for capturing this growth.

This corporate restructuring is part of SK Telecom's comprehensive AI advancement strategy. The company has also established SK Hyper, a separate entity focused on new AI data center business development, targeting a massive 5 gigawatts of capacity by 2029 and 15 gigawatts by 2035. While SK Horizon concentrates on operational excellence and infrastructure expansion, SK Hyper will drive future growth through new ventures. This dual-pronged approach allows SK Telecom to manage both current operational demands and future market opportunities effectively.

Industry observers note that the formation of specialized entities like SK Horizon is a pragmatic approach to navigating the capital-intensive and rapidly evolving data center sector. The substantial investment from sophisticated financial players like KKR and IMM Investment signals strong confidence in the long-term prospects of AI-driven digital infrastructure in the region. Yanghan Kim of KKR highlighted the stable operating platform and growing demand for AI capacity in Korea as key drivers for their investment. Similarly, Byungheon Kim from IMM Investment emphasized the critical role of AI data centers and submarine cables in securing Korea's digital sovereignty and industrial competitiveness.
