Samsung Group has committed roughly 1,000 trillion won ($648 billion) to a 10-year investment plan inside South Korea, marking what industry analysts are calling the biggest corporate spending pledge the country has ever recorded.
The commitment was laid out during a national briefing led by President Lee Jae Myung on June 29, where Samsung Electronics Chairman Lee Jae yong joined SK Group Chairman Chey Tae Won to explain how the money will be spent. According to their brief, the bulk of it will be going toward semiconductor manufacturing and artificial intelligence (AI) infrastructure, two industries South Korea sees as central to its economic future.
Where The Money is Going
Samsung’s plan spans several regions and business lines. A large share is earmarked for a new semiconductor cluster in the southwestern city of Gwangju, where the company intends to build front end fabrication plants (fabs) alongside back end packaging facilities. Another portion is going toward expanding existing chip campuses in Pyeongtaek, Hwaseong, Giheung and Yongin, sites that officials say are nearing their limits for power and water.
Samsung Display, Samsung SDI and Samsung Electro Mechanics are also folded into the plan, with money set aside for next generation OLED screens, batteries and semiconductor substrates in the Chungcheong and Yeongnam regions. And a separate chunk of the money supports AI data centers, including one planned in South Jeolla province that the government describes as a step toward a domestically controlled AI system.
Why Now
The scale of the spending can be traced back to a supply problem. Global demand for high bandwidth memory, the specialized chips that power AI accelerators, especially from companies like Nvidia, has outpaced what Samsung and SK Hynix can produce. In fact, it is rumored that existing production hubs around Seoul are running out of room to expand safely, since building more fabrication plants there would strain the region’s electricity and water supply.
Government policy adviser Kim Yong beom has said the country needs to pull forward projects originally slated for the mid 2040s into the mid 2030s just to keep pace with this demand. And President Lee has also framed the investment as necessary to stay ahead of rivals in the AI Arms Race, including the United States and China.
The Regional Politics Behind the Plan
Much of the new spending is directed away from Seoul and toward South Korea’s southwest, a region that has historically lagged behind the capital economically. Gwangju and South Jeolla province stand to gain new fabs, jobs, and infrastructure funding.
However, opposition lawmakers have pushed back, arguing the location choices favor a political stronghold of the ruling Democratic Party rather than pure business logic. Communities in existing chip hubs like Icheon have also raised concerns that shifting investment south could eventually shrink output and tax revenue where SK Hynix already operates.
What Could Slow This Plan Down
Building an advanced chip cluster from scratch requires specialized workers, reliable power and water systems, none of which currently exist at scale in the southwest. This timeline matters because the government is now asking Samsung and SK Hynix to compress similar construction schedules by as much as 12 years, moving fab completions originally planned for the mid-2040s into the mid-2030s. Doing this in roughly a decade which may have previously taken closer to two increases the execution risk considerably, especially in a region that has never hosted chip manufacturing at this scale before.
The infrastructure problem the companies are trying to escape in Seoul does not disappear once they relocate, as it has to be solved from scratch in the southwest instead. A single semiconductor fab costs at least 60 trillion won to build, and the plan calls for multiple new fabs across Gwangju alone. This is on top of the packaging, display and battery facilities spread across other regions, which means a lot of capital has to be deployed on a compressed timeline, in a location that still needs new power grids and water systems built to support it.
Now whether the plan succeeds will likely come down to two things that are already measurable going forward – equipment orders placed with suppliers like ASML and Tokyo Electron, which normally arrive 12 to 18 months before a fab actually ramps up production, and how closely the government’s promised support on permitting, power and water keeps pace with the construction schedule Samsung and SK Hynix have committed to.
