South Korea Bets $1 Trillion on Memory Chips and Humanoid Robots in Three Mega Projects Plan — What It Means for the Global AI Race

South Korea’s Boldest Industrial Bet Yet

South Korean President Lee Jae Myung on Monday unveiled the country’s most ambitious industrial investment plan in history — a 1,350 trillion won (approximately $880 billion to $1 trillion) package spanning semiconductors, AI data centres and humanoid robots. Dubbed the “Three Mega Projects” initiative, the plan is designed to cement South Korea’s technological leadership in the artificial intelligence era while addressing domestic economic imbalances.

The announcement, made at a high-profile event at the presidential Blue House in Seoul, brought together the leaders of Samsung Electronics and SK Group — two companies that together produce roughly two-thirds of the world’s memory chips. President Lee framed the investment as a national imperative, declaring that “speed is the only way to survive” in the intensifying global AI race.

Four New Chip Fabs and a Second Semiconductor Hub

The centrepiece of the plan is an 800 trillion won ($518 billion) commitment from Samsung Electronics and SK Hynix to build four new semiconductor fabrication plants in South Korea’s southwestern Gwangju and Jeolla region. This marks the first major break from the country’s decades-long concentration of chip manufacturing in the Seoul metropolitan area.

Samsung will construct two fabs in the city of Gwangju, where potential sites include the grounds of a military air base slated for relocation. SK Hynix will build two additional fabs in the same general region, though the company is still finalising exact locations. SK Group Chairman Chey Tae-won noted that assembling the company’s current flagship cluster took nine years, underscoring the scale and complexity of the endeavour.

The new facilities are being fast-tracked to come online by 2034-2035 — a dramatic acceleration from earlier projections that had pencilled in a 2044 timeline. The goal is to double South Korea’s dynamic random-access memory (DRAM) production within five years. Both companies have been reporting record profits as AI infrastructure investment drives explosive demand for high-bandwidth memory (HBM) chips.

AI Data Centres: An 18.4 GW Build-Out

Beyond chip manufacturing, the second pillar of the plan involves a massive expansion of AI data centre capacity. SK Group, GS Group and Naver have pledged 550 trillion won toward building 8.4 GW of data centre capacity by 2029, expanding to 18.4 GW by 2035. The ambition extends beyond infrastructure — the government aims to develop a general-purpose “world model” for physical AI that can power autonomous systems across industries.

SK Group Chairman Chey Tae-won went further, pledging a combined 2,100 trillion won (over $1.4 trillion) across both chips and data centres by 2035 — a figure that dwarfs even the official government package. The plan positions South Korea to compete directly with the massive AI infrastructure build-outs underway in the United States, China and Taiwan.

The global tech sell-off triggered by concerns over hyperscaler AI spending earlier this month sent mixed signals to markets, but South Korea’s bet suggests that the country’s corporate leaders see the long-term demand trajectory as unambiguously positive.

Humanoid Robots: From 1% to 20% Global Market Share

The third pillar — physical AI, particularly humanoid robots — represents South Korea’s most ambitious leap. The government wants to grow the country’s share of the global humanoid robot market from just 1% currently to 20% over the long term. To seed early demand, the government will itself procure humanoids for education, defence and disaster response applications.

Industry Minister Kim Jung-kwan warned that China has already begun mass-producing humanoid robots through regional manufacturing hubs, underscoring the urgency of the effort. “We must accelerate the foundation for mass production,” Kim said. Samsung will site its robot development work, including humanoids, in the city of Gumi. Science Minister Bae Kyung-hoon described the “next three years as the golden time to lead physical AI.”

Why South Korea Is Moving Now

The timing of the announcement is driven by several converging factors. AI-driven demand for memory chips is accelerating at a pace that has caught even industry veterans by surprise — orders are rising so fast that capacity once planned for the 2040s is now expected to be needed a decade earlier. A global memory shortage has driven up component costs, with Apple and Microsoft both raising prices on certain product lines last week.

Geopolitically, the plan competes directly with the US CHIPS Act, China’s $295 billion national AI infrastructure plan, and rising Japanese chip subsidies. South Korea finds itself squeezed between its strategic allies and its largest trading partner, China, making self-reliance in advanced chip production a matter of economic security.

Domestically, President Lee is using the plan to address decades of regional economic imbalance by channelling investment away from the over-concentrated Seoul area to poorer southwestern provinces — a move that also helps shore up his domestic political standing amid slipping approval ratings.

The Risks: Oversupply, Power and Talent

Despite the scale of ambition, analysts have flagged several significant risks. Markets reacted cautiously — Samsung shares fell nearly 5% on the announcement, and SK Hynix shares also slipped, reflecting concerns that the massive capacity additions could lead to oversupply in the memory market. A KAIST professor cautioned that “money alone does not build leading fabs,” pointing to the infrastructure, talent and water constraints that even well-funded projects face.

South Korea already faces power grid pressures, and adding 18.4 GW of data centre capacity will require massive renewable energy investment. The government has emphasised the southwest region’s strength in renewable energy as a competitive advantage, but execution on this scale carries inherent risk. The plan as a whole amounts to roughly 5% of South Korea’s 2024 GDP — a national commitment that leaves little margin for error.

India Angle: What South Korea’s Mega-Bet Means for India’s Chip Ambitions

South Korea’s announcement carries direct implications for India’s semiconductor ambitions. The two countries launched the India-Korea Digital Bridge initiative in April 2026, a framework for cooperation in AI, semiconductors and digital infrastructure. India’s own semiconductor mission, with its ₹76,000 crore incentive outlay, has 13 approved projects either operational or under development — but the scale of South Korea’s $518 billion chip commitment highlights just how far India has to go.

However, there are offsetting opportunities. India’s electronics manufacturing ecosystem, driven by the Production-Linked Incentive (PLI) scheme, is a major consumer of memory chips. The expansion of South Korean chip capacity could help stabilise global memory supply, potentially reducing costs for Indian electronics manufacturers and data centre operators. Additionally, India’s strength in chip design talent — a resource South Korea needs — positions it as a natural partner for the expanded South Korean semiconductor ecosystem.

The projection that AI could add $1 trillion to India’s GDP by 2035 critically depends on reliable access to advanced chips and memory. As South Korea and other nations race to build capacity, India must ensure its policy environment attracts a proportionate share of global semiconductor investment, or risk falling further behind in the AI infrastructure race.
