The South Korea Hyperscale Data Center Market encompasses large-scale computing infrastructure purpose-built to support cloud services, artificial intelligence workloads, big data analytics, and enterprise IT operations at scale. These facilities - characterised by IT load capacities exceeding 10 MW and standardised modular architectures - are operated by global cloud providers, domestic telecom conglomerates, and specialist colocation operators. As of 2025, South Korea hosts approximately 147 data centers with over 591 MW of operational capacity, making it the sixth-largest data center market in the Asia-Pacific region. The market is valued at USD 4.47 Billion in 2025, propelled by the convergence of AI-driven compute demand, 5G network densification, and the government's landmark Digital New Deal, which targets investment exceeding USD 40 billion in digital technologies.

The South Korea hyperscale data center market growth is reinforced by a wave of unprecedented investment commitments from global and domestic players. In June 2025, SK Group and Amazon Web Services announced a USD 5.1 billion co-investment to develop South Korea's largest single-site hyperscale AI data center in Ulsan, with planned IT capacity reaching 1 GW - cementing the country's emergence as a Northeast Asian AI infrastructure hub. The government has further committed to allocating approximately USD 2.9 billion in partnership with the private sector to construct a national AI computing centre by 2030. Meanwhile, Seoul's vacancy rate fell below 6% in 2024 as demand outpaced supply, redirecting new capacity investments to secondary cities including Busan, Incheon, and Chungcheong Province, broadening the geographic distribution of South Korea's hyperscale footprint.
