The SK Hyper AI Data center development arm of South Korean conglomerate SK Group is seeking $350 billion in external capital to launch a massive infrastructure expansion across South Korea.

Executive leaders have opened formal discussions with global technology companies and private equity investors to construct high-density computing facilities.

This ambitious digital initiative follows regional Asia-Pacific development trends highlighted in Largest Data Centers Around the World with Over 1GW Capacity Under Construction, which tracked the rapid emergence of gigawatt-scale AI infrastructure projects across South Korea and neighboring markets.

Financing Strategy for SK Hyper AI Data Infrastructure

Company executives structured the $350 billion capital campaign to fund the initial 5-gigawatt development phase of a larger 15-gigawatt master plan.

The organization aims to finalize its first external financing arrangements by late 2026 or early 2027. Consequently, management will sequence future investments across multiple funding rounds over the next three to four years.

Chief executive officer Chung Suk-geun confirmed that market demand will directly dictate the pace of physical construction. “We will adjust our capital deployment and facility construction in direct alignment with real customer demand rather than committing the total capital upfront,” stated Chung Suk-geun, chief executive officer of SK Hyper.

Furthermore, parent company SK Telecom committed 750 billion won ($567 million) in direct equity capital to support preliminary engineering works through 2030. The developer plans to enter tenant cost-sharing agreements with major hyperscalers to reduce debt exposure.

Regional Locations and SK Hyper AI Data Facility Designs

Engineering plans designate the southern industrial city of Ulsan as the flagship site for a 900-megawatt mega data complex. In addition, the developer is advancing a 100-megawatt facility in partnership with Amazon Web Services. Construction teams will also establish secondary cluster facilities across the regional Chungcheong and Honam provinces to distribute power loads across the national grid.

Specialized contractors will install advanced direct liquid cooling systems and high-capacity electrical transformers to support heavy artificial intelligence workloads. In addition, developers are negotiating power purchase agreements with utility providers to secure clean energy supplies. Official statements from management emphasize that flexible facility modularity remains crucial for maintaining long-term financial viability.

“Our primary goal is establishing scalable infrastructure that accommodates next-generation computing hardware while sharing development risk with major tenant partners,” added Chung Suk-geun, chief executive officer of SK Hyper.

Project planners expect the initial 5-gigawatt phase to create thousands of specialized construction and civil engineering jobs across South Korea. Construction teams will break ground on primary foundation works as individual site permits and financing agreements close.
