Samsung Group sets 1,000 trillion won investment plan to expand South Korea’s AI semiconductor footprint

Key Takeaways

• Samsung Group plans to invest 1,000 trillion won to expand AI chip and data center capacity across South Korea.
• The initiative aligns with accelerating AI memory demand and national efforts to ease regional infrastructure bottlenecks.
• Multiple analysts see the investment fitting into global semiconductor and AI infrastructure growth trends.

Samsung Group is preparing one of the largest national industrial commitments in South Korean history, outlining a decade-long plan valued at 1,000 trillion won, or about $648 billion, to reshape the country's AI semiconductor and advanced manufacturing landscape. The announcement is expected Monday at a meeting with the South Korean president, where Samsung Electronics, SK Hynix, and other senior executives will detail how the funding will be deployed well beyond the dense Seoul metropolitan cluster.

The idea of dispersing semiconductor assets across new regions is not entirely new, but the scale being discussed, including a potential 300 trillion won allocation for chip factories in the southwest, signals a far more aggressive posture. The capital region is simply running out of room. Power and water constraints are becoming too tight for the next generation of fabs, a point a presidential policy adviser touched on when noting that Samsung Electronics and SK Hynix may need to accelerate projects planned for the 2040s into the mid-2030s due to surging AI memory requirements.

This spike in demand is not occurring in isolation. AI workloads have been expanding faster than many infrastructure planners anticipated. According to IDC, global AI infrastructure spending is projected to surpass $200 billion annually by 2028, driven largely by hyperscale build-outs and national AI data center programs. If South Korea wants to remain central to the supply chain, scaling manufacturing capacity in new geographies becomes more than a political debate, it becomes a competitive necessity.

Yet the political dimension adds an interesting wrinkle. The regional distribution of semiconductor investments came under scrutiny ahead of South Korea's June 3 local elections, and the topic has lingered. Balanced development has been one of the government's policy priorities, and the semiconductor sector has frequently been criticized for being overly concentrated near Seoul. This massive plan, touching AI data centers, batteries, displays, and other advanced technologies, lands in the middle of a larger national conversation about which regions should benefit from the next wave of jobs and infrastructure.

A question that often arises in moments like this is whether the global market can support such rapid scale expansion. Industry watchers tend to think so. AI chip revenue has been climbing at a pace that continues to surprise analysts. Gartner projected in its 2024 semiconductor revenue outlook that the sector would reach $624 billion in 2024, with AI-specific components like GPUs and accelerators driving double-digit growth. The pace of transition toward AI-specialized silicon has reorganized capex strategies across fabs worldwide, a trend that strengthens the rationale for Samsung Group's move.

At the same time, the competitive race in high-bandwidth memory is becoming increasingly intense. Omdia's assessment of more than 40% CAGR for HBM demand frames the accelerating rivalry between Samsung Electronics and SK Hynix. Those two firms dominate AI memory production, and both have the technical depth to influence where global customers place their long-term bets. This dynamic helps explain why the government sees semiconductor investment as a national security and economic stability issue.

The broader macroeconomic context further supports this expansion. Analysts at McKinsey have suggested that generative AI could add between $2.6 trillion and $4.4 trillion in annual global economic value. Samsung Group's plan aligns with this trajectory, because none of that prospective economic output materializes without robust semiconductor and cloud infrastructure bases. Countries that move early to create fabrication and data center density often see compounding returns in jobs, supplier ecosystems, and innovation clusters.

There is also a practical dimension under discussion inside the presidential office. The administration is preparing to introduce mega projects intended to drive a national leap forward. While the office has not confirmed specific contents, the involvement of top Samsung Electronics and SK Hynix leadership signals that semiconductors will sit near the center of the upcoming announcements.

Samsung Group's structure also matters. The conglomerate is more than Samsung Electronics; battery maker Samsung SDI and IT services provider Samsung SDS are likely to play roles in the broader plan, especially as AI data center growth intersects with energy storage and systems integration requirements.

Samsung Group and SK Hynix have declined to comment on the report ahead of the official announcement. Investors, suppliers, and regional governments will be watching closely to see which regions receive long-awaited facilities and what timelines become official.

The upcoming initiative aims to address both short-term capacity constraints and longer-term structural challenges. South Korea already invests more than 4.5% of GDP in R&D, one of the highest ratios among OECD countries, providing a strong base for this expansion. What remains to be seen is how quickly the major chipmakers can operationalize their accelerated timelines and whether the country's infrastructure can keep pace with the massive shift in global AI demand.
