Samsung Group formally announced a 1,000 trillion won investment in South Korea today — roughly $648 billion over the next decade — at a government briefing session chaired by President Lee Jae Myung. The package includes AI data centers, chip factories, batteries, and displays, and is being described as the largest corporate investment commitment ever announced by a South Korean company.

The announcement came days after Samsung Chairman Lee Jae-yong met with President Lee at the presidential office on June 25 to align on the scope of the plan. SK Hynix executives also attended today’s briefing, laying out their own investment targets to complement Samsung’s commitment.

What the $648 Billion Actually Covers

The investment is spread across Samsung’s affiliates and divisions. Samsung Electronics alone is committing to a nationwide semiconductor ecosystem — not just at its established Yongin site, where about 60 trillion won will go toward chip plants, but also extending to Chungcheong, Yeongnam, and Incheon regions. That geographic spread is deliberate: the government has been pushing to distribute industrial activity beyond Seoul and its surrounding hubs.

More than 350 trillion won of the total is earmarked for AI infrastructure, primarily data centers. Samsung Display is committing 100 trillion won over the decade. Samsung SDI plans to expand its Cheonan plant for next-generation battery production. Samsung Electro-Mechanics is boosting output of high-value substrates for AI semiconductors at its Sejong plant. It is a full-stack investment across the AI hardware supply chain.

Why Samsung Is Doing This Now

AI demand has changed the math for chipmakers. DRAM and NAND prices are recovering sharply after the inventory correction of 2023-2024, and the wave of AI data center buildout — from hyperscalers in the US to sovereign AI programs in Asia — has created a decade-long order book for advanced memory and logic chips. Samsung and SK Hynix are the primary suppliers for high-bandwidth memory used in AI training and inference systems.

The government’s “National Mega Projects” initiative gave Samsung a political and logistical framework to commit to scale. Tax incentives for chip factories in designated regions, accelerated permitting, and infrastructure investment from the state all make the economics of the commitment more viable than a purely private-sector decision would be.

What This Means for South Korea and Global Chip Supply

A $648 billion commitment from a single conglomerate reshapes industrial geography. New chip factories in the southwest, Chungcheong, and Yeongnam regions would create hundreds of thousands of jobs outside Seoul, which has been a policy objective for the current administration. For global supply chains, more Samsung manufacturing capacity reduces the concentration risk that exposed the semiconductor industry during the 2021-2022 shortage.

The commitment is a decade-long pledge, which means execution risk is real. Samsung’s balance sheet has recovered significantly from its 2023 downturn, but a global recession or sustained AI demand slowdown could slow spending. For now, the company and the government are aligned — and the announcement today formalizes that alignment.

$648 billion over ten years is the largest bet any single company has made on the AI chip era. Whether it pays off depends on whether that era lasts as long as everyone assumes it will.

FYI (keeping you in the loop)

What is Samsung’s 1,000 trillion won investment plan in South Korea?

Samsung Group pledged 1,000 trillion won (about $648 billion) over 10 years to build AI data centers, chip factories, batteries, and displays across multiple South Korean regions. The formal announcement was made on June 28, 2026 at a government briefing with President Lee Jae Myung.
