The global race for AI dominance is no longer just about building better models. It is increasingly becoming a race to secure the infrastructure that powers artificial intelligence. And South Korea is preparing to make one of its biggest bets yet.
According to reports, Samsung Group and SK Group are set to invest as much as 2,000 trillion won ($1.3 trillion) over the next decade across semiconductors, data centers, robotics and related technologies.
If confirmed, this would rank among the largest long-term technology investment plans ever announced.
Why Is South Korea Spending So Much?
Artificial intelligence runs on an enormous amount of computing power.
Behind every AI chatbot, image generator and autonomous system lies a vast network of:
- Advanced memory chips
- High-performance processors
- Massive data centers
- Robotics and automation infrastructure
South Korea already occupies a crucial position in this ecosystem.
The country is home to Samsung Electronics and SK Hynix, the world’s two largest memory chip manufacturers. Their high-bandwidth memory (HBM) chips have become indispensable for AI applications, particularly in data centers used by companies such as Microsoft, OpenAI and other hyperscalers.
As AI adoption accelerates globally, Seoul wants to ensure the country remains at the center of this supply chain.
A National Strategy, Not Just Corporate Spending
The investment push appears to be closely aligned with President Lee Jae Myung’s broader economic vision.
The initiative, reportedly called “Three Mega Projects for the Big Stride Forward,” aims to achieve multiple goals simultaneously:
- Preserve South Korea’s leadership in memory semiconductors.
- Strengthen national security through domestic technology capabilities.
- Reduce economic concentration around Seoul.
- Create high-paying jobs in regional cities.
- Build new growth engines for the economy.
For decades, South Korea’s economic growth has been heavily centered around the Seoul metropolitan region. The new plan seeks to spread industrial investment across other provinces.
New Semiconductor Hubs Beyond Seoul
Reports suggest Samsung and SK Hynix plan significant regional expansion.
Potential projects include:
Samsung
- Construction of multiple semiconductor facilities in the Gwangju region.
- Expansion of advanced chip packaging operations in South Chungcheong Province.
SK Hynix
- Additional semiconductor plants in the Gwangju area.
- Expansion of NAND flash manufacturing in North Chungcheong Province.
These projects could transform regional economies by attracting suppliers, engineering talent and supporting industries.
The AI Infrastructure Race Is Intensifying
South Korea’s move comes as governments worldwide aggressively support domestic semiconductor production.
Several countries are treating chips as a matter of economic and national security.
Examples include:
- The United States, through the CHIPS and Science Act, has committed tens of billions of dollars to semiconductor manufacturing.
- China continues to invest heavily to build a self-sufficient semiconductor ecosystem amid ongoing technology restrictions.
- Japan has dramatically increased subsidies to revive its chip sector and support investments from both domestic companies and foreign manufacturers.
The competition is fierce because semiconductors have become the backbone of the digital economy and AI revolution.
How Big Is This Investment?
To put the numbers into perspective:
- The reported $1.3 trillion investment spans ten years.
- Global hyperscalers are expected to spend hundreds of billions annually on AI infrastructure.
- Samsung alone has already indicated plans to spend more than $70 billion in 2026.
- Taiwan Semiconductor Manufacturing Co. is expected to spend around $56 billion this year.
The sheer scale highlights how capital-intensive the AI era has become.
Building leadership in AI increasingly requires enormous investments in factories, power infrastructure, cooling systems and advanced manufacturing technologies.
Not Everyone Is Convinced
Despite the long-term optimism around AI, investors are becoming more cautious.
Shares of both Samsung Electronics and SK Hynix recently fell sharply, reflecting concerns that:
- AI-driven demand may eventually moderate.
- Competition in memory chips is intensifying.
- Massive capital expenditures could pressure profitability.
- The current pace of AI spending may not be sustainable indefinitely.
The market is effectively asking a difficult question: Can AI demand continue growing fast enough to justify these enormous investments?
For now, both companies appear willing to bet that the answer is yes.
What This Means for Investors
South Korea’s proposed investment plan reinforces a broader trend visible across the world:
The AI boom is evolving into an infrastructure boom.
While consumer-facing AI applications often grab headlines, much of the economic value may ultimately accrue to companies building the underlying infrastructure:
- Semiconductor manufacturers
- Chip equipment suppliers
- Data center operators
- Power and cooling providers
- Robotics and automation firms
For investors, the next decade of AI may be defined not just by software breakthroughs, but by who builds and controls the physical infrastructure powering the technology.
And South Korea is making it clear that it intends to remain one of those builders.
