Key Takeaways:
Samsung Group's planned 1,000 trillion won investment — the largest corporate spending pledge in South Korea's history — would reshape the country's semiconductor map and deepen the global chip manufacturing arms race.
Samsung Group will announce on Monday plans to invest 1,000 trillion won ($647.53 billion) in South Korea over 10 years, including as much as 300 trillion won to build chip factories in the southwest of the country, according to a Maeil Business Newspaper report. The announcement will be made at a meeting with President Lee Jae Myung at the presidential office, with executives from Samsung Electronics and rival SK Hynix in attendance.
"The investment is aimed at regions outside Seoul and nearby cities, where chipmakers have concentrated their production facilities," the newspaper reported, without citing sources. The companies have faced mounting pressure from policymakers to distribute manufacturing capacity more evenly across the country.
The 300 trillion won semiconductor fab allocation alone would fund multiple fabrication plants on a scale comparable to Samsung's existing Pyeongtaek campus — currently the world's largest semiconductor production facility. The southwest region, which includes cities such as Gwangju and Naju, has historically been an underinvested area for the chip industry compared with the Seoul metropolitan area and the central city of Cheonan.
The Regional Competition Heats Up
The announcement comes as cities across South Korea compete aggressively for semiconductor investment. Gumi, a city in North Gyeongsang Province, this week offered industrial land at roughly 1,000 won per pyeong (about $200 per square meter) — a 1.2 trillion won subsidy package — to lure fab construction to its Fifth National Industrial Complex. Gumi Mayor Kim Jang-ho said the city already hosts 309 semiconductor materials, parts and equipment companies including SK Siltron and LG Innotek.
The presidential office said on Thursday it planned to hold a public briefing on "three mega-projects for South Korea's great leap forward," signaling that the Samsung investment may be part of a broader national industrial strategy. Details on the meeting will be announced soon, the office said.
What It Means for the Global Chip Race
The investment positions Samsung to challenge Taiwan Semiconductor Manufacturing Co.'s dominance in advanced logic manufacturing. Samsung Foundry currently trails TSMC in market share for sub-7nm nodes but has been investing heavily in its 2nm and 3nm process technologies. A 300 trillion won fab buildout — equivalent to roughly $194 billion at current exchange rates — would give Samsung the capacity to absorb orders from AI chip designers seeking an alternative to TSMC's tightly booked production lines.
For SK Hynix, the meeting signals that South Korea's two largest chipmakers are coordinating with the government on a national semiconductor strategy. SK Hynix dominates the high-bandwidth memory (HBM) market — a critical component for Nvidia's AI accelerators — and any new fab investment would likely target HBM and advanced DRAM production.
The broader KOSPI index has surged close to 200% over the last 12 months, driven by retail investor demand for AI-related chip stocks, according to Bloomberg data. Samsung Electronics and SK Hynix account for a disproportionate share of the index's $4.7 trillion market capitalization, making South Korea's equity market uniquely sensitive to semiconductor cycle risk.
Samsung was not immediately available for comment outside business hours. The company's shares trade on the Korea Exchange under ticker 005930.KS.
