SK Telecom launches dedicated AI infra company
SK Telecom said it created SK Hyper to oversee end-to-end development of its AIDC business, including land acquisition, substation construction and operations, customer attraction, and commercialization. The board approved up to KRW 750 billion (about $540 million) through 2030 to build up to 15GW of AI data center capacity, with 5GW targeted from 2029.

The 30-second read
Why it matters
By establishing SK Hyper with board-approved funding and end-to-end responsibility (land, substations, customer attraction, commercialization), the company is formalizing execution for a 15GW AI data center capacity roadmap with a first 5GW phase targeted for 2029.
Market read
Traders may reassess SK Telecom’s AI infrastructure strategy and potential capex trajectory after a concrete subsidiary creation and multi-year investment commitment.
What to watch
Key sensitivities are power availability and substation permitting timelines, customer take-rates for the 2029-2035 phases, and whether the $540M figure is sufficient relative to total 15GW capex needs.
Background
SK Telecom previously created an AI data center integrated development division reporting to the CEO, and in June it partnered with Nvidia on a gigawatt-scale AI Cloud using Nvidia DSX AI factory architecture.
Market effects
Could increase demand expectations for South Korea power infrastructure, data center construction, and AI cloud capacity providers tied to hyperscale buildouts.
Supports a Korea-focused AI data center cluster build in Ulsan, then Chungcheong and Honam, potentially affecting regional grid and land-use planning.
If executed, the 15GW roadmap may strengthen South Korea’s role in sovereign and enterprise AI compute supply chains, with potential read-through to global AI infrastructure partners.
Counterpoint
The plan may be more about capacity ambition than contracted revenue, so market may discount it until customer commitments and utilization targets are disclosed.
