Key Takeaways
- The investment targets 18.4 GW AI data center capacity by 2035
- A 550 trillion won phase will build 8.4 GW by 2029
- The semiconductor firms commit 800 trillion won to chip infrastructure expansion
South Korea AI data center expansion plans include a $650 billion investment by 2035 to strengthen the country’s position in advanced computing and semiconductor industries. The initiative focuses on scaling computing capacity and securing data resources to support the next phase of AI-driven industrial growth.
Infrastructure expansion and capacity targets
The plan includes an initial investment of 550 trillion won to build AI data centers with a combined capacity of 8.4 gigawatts by 2029. This will be followed by an additional 10 gigawatts of capacity expansion by 2035, taking the total planned infrastructure to 18.4 gigawatts.
The South Korea AI data center expansion reflects the growing demand for computing power needed to train and deploy advanced artificial intelligence systems. AI data centers support high-performance chips and require significant energy for both processing and cooling operations. The planned capacity places South Korea among the largest global markets for AI infrastructure deployment.
The strategy emphasizes the role of physical AI, which includes systems designed to operate in real-world environments such as robotics, autonomous platforms, and connected devices. Increasing compute capacity and data availability are identified as key requirements for advancing these applications.
Semiconductor investment and industry alignment
The AI infrastructure plan is supported by parallel investments in semiconductor manufacturing. Samsung Electronics and SK Hynix have announced a combined investment of 800 trillion won in chip production facilities.
These investments include the construction of two advanced semiconductor fabrication plants in the southwest region. In addition, up to 81 trillion won will be allocated toward developing a semiconductor packaging cluster near Seoul, aimed at enhancing supply chain efficiency and production capabilities.
The alignment between AI infrastructure and semiconductor capacity is intended to support end-to-end development of computing systems. Data centers require advanced chips for processing workloads, while semiconductor production depends on consistent demand from AI applications.
The scale of investment reflects increasing competition in global AI and semiconductor markets. Expanding domestic production and infrastructure capacity is seen as essential for maintaining growth in technological industries.
