"Samsung Electronics and SK Hynix shares fell on Monday as reports emerged of a $1.3 trillion investment plan, with the companies set to unveil details during a government briefing. The announcement follows earlier reports of Samsung’s 1,000 trillion won ($646 billion) investment, according to CNBC and Fortune.
Government Announces Revised $1.3 Trillion Investment Plan for Semiconductors and AI
Samsung Electronics and SK Hynix are poised to announce a $1.3 trillion investment over the next decade, focusing on semiconductor fabs, AI data centers, and physical AI, according to reports from Korea Economic Daily and Fortune. The plan, set to be unveiled at a presidential briefing on June 29, includes four to five new semiconductor fabrication plants in Gwangju, with Samsung also expanding chip packaging in South Chungcheong and SK Hynix targeting NAND plant upgrades in North Chungcheong. Presidential policy chief Kim Yong-beom described the figures as "very unusual," signaling a shift from earlier estimates of Samsung’s standalone $646 billion commitment.

The scale of the investment reflects South Korea’s push to diversify industrial hubs beyond the Seoul metropolitan area, a priority for President Lee Jae Myung. "Breaking free from overconcentration in the Seoul area is a key challenge," Deputy Prime Minister Gu Yoon-cheol stated, emphasizing the need for regional development. The plan also includes 800 trillion won ($517.9 billion) in corporate investments for a "second semiconductor cluster" in the southwest, as outlined by Industry Minister Kim Jung-kwan.
Opposition Criticizes Government’s Regional Development Strategy as Politically Motivated
The investment plans have ignited political clashes, with opposition leader Lee Joon-seok of the New Reform Party accusing the government of "prescribing before diagnosing" regional development. "If the name of the disease doesn’t match the patient, the government has dealt with the patient instead of fixing the diagnosis," he said, criticizing the "Honam Semiconductor Cluster" initiative as a political maneuver. His remarks, shared on social media, drew comparisons to medical malpractice, highlighting fears of corporate coercion.

Conversely, the ruling party frames the project as a solution to Seoul’s infrastructure bottlenecks. "We must not only paddle when the tide rises but also build larger ships in various locations," Gu Yoon-cheol argued, citing power and water shortages in the capital. However, critics like Lee Joon-seok accuse the administration of "pulling out the patient’s respiratory tract" by cutting electricity to Yongin to force regional investment.
Stock Market Rally Highlights Speculative Bets on Semiconductor Cluster Announcements
Local stock markets reacted sharply to the rumors, with construction firms in Gwangju and South Jeolla seeing surges of up to 30%. Kumho E&C hit its daily trading limit after a 29.9% jump, while Namhwa Construction and Bohae Brewery also saw gains. However, analysts warned of speculative buying, noting that some companies, like Ilshin Spinning, saw rallies despite no direct ties to the chip industry.
The frenzy extended to companies with historical ties to the region. Kumho Electric, now based in Seoul, saw a 30% surge after being mistakenly linked to the cluster, while Kumho Tire’s Gwangju plant sparked speculation about land sales. "Outdated information or unfounded claims linking companies to the region drove part of the rally," industry officials said, cautioning that only firms with local expertise would benefit long-term.
Water and Power Constraints Threaten Feasibility of Southwest Semiconductor Expansion
President Lee’s vision hinges on solving logistical challenges, particularly water and power shortages in the southwest. Presidential policy chief Kim Yong-beom dismissed claims of a "water shortage" as "unreasonable," citing plans to secure 1 million tons of industrial water daily through dam heightening and agricultural water reallocation. "The water resources that have nourished Korean civilization are just as abundant in the southwest as in Yeongnam," he stated, defending the region’s viability.

Yet, the push faces hurdles. The existing Yongin semiconductor cluster, a key project, has faced delays due to power constraints, with officials cutting electricity to "protect the diagnosis" of regional development. Critics argue the approach risks repeating past mistakes, where infrastructure gaps derailed industrial growth.
The June 29 briefing will determine the final shape of the "Three Mega Projects," including AI data centers and physical AI. Samsung’s plan spans four regions—Honam, Chungcheong, Yeongnam, and Incheon—while SK Hynix focuses on NAND expansion. The government aims to balance economic growth with regional equity, but political divisions and logistical challenges loom large.
For investors, the stakes are high. GlobalFoundries and Applied Materials, key suppliers to Samsung and SK Hynix, may benefit from the expanded capacity. Yet, the immediate market reaction—Samsung down 4.7%, SK Hynix 3.1%—suggests skepticism about the financial feasibility of such a massive rollout.
As South Korea races to solidify its semiconductor dominance, the coming weeks will test whether this $1.3 trillion gamble translates into tangible progress—or becomes another chapter in the country’s fraught history of industrial overreach.
