Samsung and SK Hynix Prep $646 Billion Decade Investment Plan

Samsung Group and SK Hynix will on Monday unveil a decade-long investment plan worth 1,000 trillion won ($646 billion), the largest corporate spending package ever announced by a Korean company, anchored to a semiconductor and AI build-out designed to extend South Korea’s grip on the global memory chip market. The two companies are South Korea’s two most valuable firms and the world’s leading memory chipmakers. Top executives from both are expected at a presidential briefing at Cheong Wa Dae on June 29.

The package was drawn up after a dinner between President Lee Jae Myung and Samsung Electronics Chairman Lee Jae-yong. More than 350 trillion won of the total is expected to flow into chips and AI infrastructure, with the rest covering advanced displays, next-generation batteries and regional industrial expansion, according to a Friday report in Maeil Business Newspaper carried by the trillion-won plan to expand beyond Seoul. South Korea’s special semiconductor competitiveness law is scheduled to take effect in August. The full investment breakdown is expected to be released during Monday’s briefing at Cheong Wa Dae.

What’s Actually in the 1,000 Trillion Won Plan

The headline figure, 1,000 trillion won ($646 billion) over ten years, would exceed South Korea’s government budget of 728 trillion won. It would also approach half the country’s annual gross domestic product, according to the Korea Herald’s reading of the Maeil Business report. Samsung has not separately confirmed the numbers or the package’s detailed breakdown.

Semiconductors are the load-bearing pillar. The Korea Herald report says more than 350 trillion won, roughly a third of the announced total, is earmarked for chips and AI infrastructure, with the remainder spread across displays, batteries and the build-out of regional industrial clusters beyond the capital.

The legal scaffolding behind the build-out is set out in the August semiconductor law. It includes provisions on cluster support, faster permitting and regional balance in strategic projects. A separate presidential push for a southern semiconductor belt is also underway as part of broader industrial strategy. More details on regional allocation and possible government support measures are expected at Monday’s public-private meeting.

A Two-Track Map Beyond Seoul

The plan reads as both an industrial policy and a regional development strategy. The Korea Herald report says Samsung intends to expand into three regions historically outside the capital’s semiconductor corridor, with each region tethered to a core business.

The regional targets spelled out in the report:

• Honam: memory and display manufacturing
• Chungcheong: AI infrastructure and advanced packaging
• Yeongnam: next-generation batteries and foundry capacity

The two-track approach, continuing the existing semiconductor cluster in Gyeonggi Province while seeding new capacity across the south and west, fits the Lee Jae Myung administration’s balanced regional development agenda. That agenda names five regional hubs and three special self-governing provinces as priority growth zones. More details are expected Monday at the public-private meeting on balanced national development at Cheong Wa Dae.

Each region’s lead industry is meant to anchor a broader industrial cluster, with semiconductors and displays in Honam, AI infrastructure and advanced packaging in Chungcheong, and next-generation batteries and foundry capacity in Yeongnam. The wider package also includes battery capacity expansions and next-generation display investments, signalling that Samsung is hedging across multiple product lines beyond core memory. The combined region-by-region rollout will shape where the trillion-won outlay physically lands over the next decade.

The AI Memory Crunch Driving It

The investment lands against a backdrop of supply-constrained memory markets that both companies have publicly warned will outlast the current AI build cycle. Samsung memory chief Kim Jaejune warned in the company’s April 30, 2026 earnings report that “significant shortages” across memory products are expected to continue through at least 2027, and that customer demand fulfillment rates have fallen to record lows. SK Group chairman Chey Tae-won said earlier this year that AI-related memory demand pressure may persist even toward 2030.

The two warnings, issued separately by the world’s two largest memory suppliers, point to a multi-year shortage thesis that underpins Monday’s announced commitment to expand capacity. The figures behind that thesis are stark.

• Samsung Q1 2026 semiconductor-division operating profit: 53.7 trillion won ($36.1 billion), about 94% of the company’s total quarterly profit
• SK Hynix Q1 2026 revenue: 52.6 trillion won ($35.5 billion)
• SK Hynix Q1 2026 operating profit: 37.6 trillion won ($27.8 billion)
• Combined DRAM market share: Samsung, SK Hynix and US-based Micron control well over 90% of the global DRAM market
• Memory shortage outlook: Samsung expects significant shortages to continue through at least 2027

Both companies enter the trillion-won commitment from positions of cash-flow strength that would have been unimaginable three years ago. That financial cushion matters because the investment package stretches across ten years, through multiple expected cycles of memory pricing. It also gives both companies room to keep capex elevated through any softening in memory demand. The earnings are concentrated in memory specifically, with both companies warning that demand will run ahead of supply through at least 2027.

How Samsung and SK Hynix Stack Up

The two anchor companies are not entering this commitment from equal positions. Samsung is the larger conglomerate, with the broadest product portfolio across DRAM, NAND, foundry and displays; SK Hynix is the more concentrated memory specialist.

The split shows up in their product mix. SK Hynix’s record Q1 2026 results were driven largely by HBM sales to AI infrastructure customers including Nvidia. Samsung’s semiconductor division draws a much larger share of total operating profit but spans more product lines, leaving less concentration in any single memory segment.

The two rows track each company through the same lens. Samsung makes more operating profit from a broader portfolio. SK Hynix makes nearly as much from a tighter product set anchored in HBM. Both face the same supply-side constraint, with HBM-grade fab capacity sold out through 2026 and into 2027, according to warnings from both companies about multi-year memory shortages.

The trillion-won commitment will add HBM-grade fab capacity across the two anchor companies over the next decade. The Korea Herald report and the Maeil Business original leave the capacity split between the two companies for Monday’s presentation. Both companies have signalled, in their own public comments, that AI-driven memory demand will run ahead of supply well into the back half of the decade.

How the Bill Gets Paid

Even a decade-long plan must clear near-term financing. Both companies enter the commitment from positions of cash-flow strength that would have been unimaginable three years ago, sums large enough to fund a multi-year capex programme without external stress.

On the Korean side, the August semiconductor law and a presidential chief of staff publicly vouching for the legitimacy of the announced figures have softened the political risk of a private-sector mega-commitment. Presidential chief of staff for policy Kim Yong-beom said on a YouTube program Friday that the investment plans to be discussed Monday would involve unusually large figures. He dismissed suggestions that the government had pressured the companies into pledging them.

The numbers are so big that there will be a heated debate over whether they are real. Samsung Electronics and SK Hynix are the world’s No. 1 and No. 2 players. These are not companies that can be squeezed into doing something.

That framing positions the package as company-led, with the state providing enabling legislation and regional support, rather than as a directed industrial credit. Investors and competitors will parse the framing on Monday, when Samsung and SK Hynix detail the package at Cheong Wa Dae.

The Risk Built Into the Bet

Memory is cyclical. That fact hangs over any decade-long pledge, even one grounded in current capacity scarcity. The memory industry has historically swung between oversupply and shortages, with profitability collapsing in past downcycles. Industry reporting already flags next-generation alternatives such as 3D X-DRAM and ZAM (Z-Angle Memory), which aim to reduce power consumption and ease scaling limitations in future accelerators.

Analysts increasingly believe the current cycle is different. AI infrastructure growth is consuming hardware at unprecedented rates, and customers are reserving supply years ahead. Tom’s Hardware, citing the companies’ own earnings calls, noted that demand fulfillment rates have fallen to record lows and that some customers have already secured allocations through 2027. But “different this time” is the most expensive sentence in cyclical investing. The trillion-won bet is being made now, in front of a presidential audience, in a country whose semiconductor law is about to take effect.

What Monday Will, and Won’t, Settle

The June 29 briefing will confirm the headline number and the regional map. It will not settle how the trillion-won package is split year by year, how much capacity will be added in DRAM versus HBM versus foundry, or how Samsung plans to close its HBM share gap with SK Hynix. Those details the Korea Herald report and the Maeil Business original leave for Monday’s presentation.

What is already locked in is the strategic posture. Both companies are committing publicly to a multi-year capacity expansion while their own executives warn that demand will run ahead of supply well into the back half of the decade. Samsung and SK Hynix together control well over 90% of the global DRAM market with US-based Micron, and that concentration gives them pricing power to ride out any short-term pricing softness. The capacity addition is also designed to lock in that pricing power for another decade.

The next 72 hours will turn a leaked headline figure into a public pledge. Detailed allocation percentages and a regional map will be confirmed during Monday’s briefing at Cheong Wa Dae. The briefing agenda covers investment plans, regional allocation and possible government support measures, with industry press expected to publish day-of details.

Frequently Asked Questions

What is the Samsung and SK Hynix trillion-won investment plan?

Samsung Group is preparing to unveil a decade-long investment package worth 1,000 trillion won ($646 billion) at a presidential briefing at Cheong Wa Dae on June 29, 2026. More than 350 trillion won of the package is earmarked for chips and AI infrastructure, with the remainder spread across advanced displays, next-generation batteries and the build-out of regional industrial clusters.

Why are Samsung and SK Hynix committing to such a large investment now?

Both companies are publicly warning that AI-driven memory demand will outstrip supply through at least 2027. Samsung memory chief Kim Jaejune warned of “significant shortages” in the company’s April 30, 2026 earnings report, and SK Group chairman Chey Tae-won has said AI-related memory demand pressure may persist even toward 2030. The trillion-won commitment is the capacity-side response to that demand outlook.

How does this plan relate to South Korean government policy?

A special law on strengthening the competitiveness of the semiconductor industry is scheduled to take effect in August 2026, with provisions on cluster support, faster permitting and regional balance in strategic projects. The investment package will be detailed at a public-private meeting on balanced national development that the Korea Herald expects to include discussion of possible government support measures.

How do Samsung and SK Hynix compare to other memory chipmakers?

Samsung and SK Hynix sit at the top of a three-company bloc with US-based Micron that controls well over 90% of the global DRAM market. SK Hynix’s record Q1 2026 revenue of 52.6 trillion won ($35.5 billion) was driven largely by HBM sales to AI infrastructure customers including Nvidia, while Samsung reported a 53.7 trillion won ($36.1 billion) operating profit from its semiconductor division alone.

Will this investment lower memory chip prices?

The investment is targeted at adding capacity to a market that both companies say will remain undersupplied through at least 2027. Even with new fabs coming online, semiconductor fabrication plants and advanced memory packaging facilities take years to expand and ramp up, meaning supply growth cannot immediately catch up to AI-driven demand.
