The South Korean government announced a 4,700 trillion won semiconductor and AI mega-project on June 29 at a Blue House national briefing, with Samsung Group committing 2,655 trillion won and SK Group pledging 2,100 trillion won in combined investments. The announcement aims to diversify the country's semiconductor industry beyond memory chip production into robotics, AI data centers, and advanced packaging, addressing current market concentration in Samsung Electronics and SK Hynix stocks. Analysts expect the project to broaden Korean stock market investment themes into construction, power infrastructure, robotics, and semiconductor components sectors.
Government Announces 4,700 Trillion Won Semiconductor Mega-Project on June 29
At the 'Korea Grand Leap Forward 3 Mega Projects National Briefing' held at the Blue House on June 29, the government unveiled investment plans totaling 4,700 trillion won centered on new semiconductor fab construction, physical AI, and AI data centers. Samsung Group will invest 2,655 trillion won to build the Honam semiconductor cluster, a large-scale high-bandwidth memory (HBM) packaging fab in South Chungcheong, and a humanoid robot and smart manufacturing base in Yeongnam. SK Group will invest 2,100 trillion won by 2035 to establish an AI memory production belt connecting Yongin, Cheongju, and Honam, along with AI data centers and semiconductor operations.
The combined investment of 4,755 trillion won from both companies equals 6.5 times the government's budget (approximately 728 trillion won), marking the largest corporate investment plan in history. Securities industry analysts view this not merely as industrial policy but as a catalyst that could reshape Korean stock market investment flows.
Samsung and SK Group Commit Combined 4,755 Trillion Won Investment
Samsung Electronics Chairman Lee Jae-yong stated at the national briefing, "Robot demand will expand beyond factories to industrial sites, homes, hospitals, restaurants, and society as a whole. Samsung Group will concentrate robot investment in Gumi, North Gyeongsang Province, along with internal data centers." Samsung Electronics has been cultivating humanoid and industrial robot development as future growth engines since acquiring Rainbow Robotics in 2024.
SK Group's 2,100 trillion won investment will focus on constructing the AI memory production belt and AI data center infrastructure through 2035. The phased development will connect Yongin, Cheongju, and Honam regions into an integrated semiconductor manufacturing network.
Minister of Trade, Industry and Energy Kim Jung-kwan stated, "We will foster an advanced packaging hub in the Chungcheong region. The Southeast and Daegu regions will be developed as semiconductor components supply chain hubs and next-generation innovation bases for power semiconductors."
Korean Stocks Expected to Diversify Beyond Samsung Electronics and SK Hynix
This year's Korean stock market has been led by Samsung Electronics and SK Hynix, with capital concentrated in large-cap semiconductor stocks due to expectations of memory industry improvement driven by HBM and AI server investment expansion. This resulted in a 'K-shaped market' where the entire market moved according to semiconductor industry conditions. Critics pointed out that market polarization intensified as many sectors remained relatively neglected while semiconductor large-caps rose.
Securities industry analysts expect the government's mega-project to partially alleviate this investment concentration. As semiconductor production facilities increase, investment benefits will spread across the industrial ecosystem including materials and equipment, back-end processes, power infrastructure, and construction — not just memory companies.
Robotics Sector Gains Attention as Physical AI Becomes Core Project Pillar
With physical AI presented as one of the core pillars of this project, expectations for the robotics industry are growing again. Physical AI refers to technology that integrates generative AI into actual industrial sites, manufacturing plants, logistics, healthcare, and services. Since AI goes beyond simply analyzing data to directly control robots and automation equipment operating in the real world, it is considered a core field of next-generation industry. The Ministry of Trade, Industry and Energy also expressed its commitment to fostering related industries by presenting the direction that Korea must transition from a 'country that uses robots well' to a 'country that makes robots well.'
Attention is focused on Hyundai Motor as the government has designated physical AI as a future growth driver. Hyundai Motor plans to invest 9 trillion won in phases starting next year to build an AI data center and robot manufacturing and parts cluster on a 1.12 million square meter (approximately 340,000 pyeong) site in Saemangeum.
Construction and Power Infrastructure Stocks Surge on Announcement Day
Following the government announcement, the market has begun actively searching for various beneficiary stocks beyond semiconductor companies and robotics-related sectors. Construction stocks moved first. When the Southwest region semiconductor cluster development plan was announced, Gwangju and South Jeolla-based construction companies Kumho Construction and Namhwa Engineering & Construction hit daily price limits. Major construction stocks including Hyundai Engineering & Construction and GS Engineering & Construction also recorded double-digit gains on the announcement day.
This reflects expectations that semiconductor factory construction will generate demand for not only factories but also roads, water supply, transmission networks, housing, and various infrastructure facilities.
Expectations are also growing for power infrastructure benefits from AI data center expansion. Since AI data centers consume massive amounts of electricity — earning the nickname 'electricity-eating hippos' — investment in transformers, ultra-high voltage cables, and transmission and distribution facilities is essential. Accordingly, power equipment companies including the three major power equipment firms LS Electric, Hyosung Heavy Industries, and HD Hyundai Electric have attracted investor attention following the government announcement.
With Minister Kim Jung-kwan stating that the Chungcheong region will be developed as an advanced packaging hub and the Southeast and Daegu regions as semiconductor components supply chain hubs and next-generation innovation bases for power semiconductors, expectations are growing that investment benefits will expand to companies in advanced packaging equipment, materials, and power semiconductors.
Park Sun-young, researcher at Mirae Asset Securities, said, "Investment areas need to prioritize AI robot finished products and core components directly connected to government strategy, and physical AI development companies. In the mid- to long-term, differentiation is likely to center on demand and supply companies in manufacturing demonstration projects, and companies that secure mass production capability, customer references, and repeat orders based on government support."
