The $16 billion transformation few outside tech are watching

South Korea’s data center market is entering a rapid expansion phase as surging demand for cloud computing and artificial intelligence drives large-scale infrastructure investment, according to a new industry analysis released on January 20.

The market was valued at $5.04 billion in 2025 and is projected to more than triple to $16.23 billion by 2031, reflecting a compound annual growth rate of about 21.5 percent over the forecast period.

South Korea currently has around 58 operational colocation data centers, with more than half concentrated in Seoul, and most facilities designed to meet Tier III reliability standards. The country is now seeing a shift toward AI-ready data centers, featuring high-density racks, advanced liquid cooling systems, and significantly higher power capacity to support graphics processing unit clusters.

Major technology players are already positioning for this demand. Amazon Web Services partnered with SK Group in late 2025 to develop a facility capable of hosting roughly 60,000 GPUs, while OpenAI moved to secure electrical infrastructure equipment for its own AI-focused data center project in South Korea.

Development costs remain a competitive advantage, with average construction expenses estimated at $10 million to $11 million per megawatt, lower than those in regional peers such as Singapore, Japan, and Australia.

Industry oversight is coordinated through the Korea Data Center Council in partnership with the Ministry of Science and ICT, including the issuance of green data center certifications aimed at improving environmental performance.

Colocation operators continue to anchor investment activity, led by firms such as Equinix, Digital Realty, KT Corp., LG CNS, SK Broadband, and Macquarie Group. Hyperscale cloud providers including Alibaba, Google, Microsoft, Oracle, and Tencent are also expanding their regional footprints, with Alibaba planning a second data center in the country.

The report identifies at least 26 upcoming facilities across more than 16 locations, signaling sustained momentum as South Korea strengthens its role as a regional hub for digital and AI infrastructure.
