South Korea's 2027 budget: 21.3 trillion won for AI chips, data centers and physical AI, nearly double this year

South Korea plans to spend 21.3 trillion won (about $16 billion) in 2027 on semiconductors, AI data centers and "physical AI" such as robots and smart factories, nearly double this year's level. President Lee Jae Myung set out the plan on Monday 2 November in his budget speech to the National Assembly, as part of a record 820.9 trillion won ($610 billion) spending proposal. The money matters beyond Korea: it is a state-funded bet on the same three things that decide who can train and run AI at scale, which are chips, power and compute.

Key points

• Lee's 2027 budget totals 820.9 trillion won ($610 billion), up 12.8%, the largest in South Korea's history (Korea Herald).
• Spending on the three "megaprojects" (semiconductors, physical AI and AI data centers) is set at 21.3 trillion won, up 97.2% from this year, according to the Ministry of Planning and Budget.
• The plan includes 4.7 trillion won for frontier AI development and 2.1 trillion won for power, water and industrial-site infrastructure.
• The government says it will supply 10,000 GPUs to a national AI foundation model project, and creates a special account for the semiconductor industry.
• The Assembly has until 2 December, the statutory deadline, to pass the budget, and the opposition has already objected to the fiscal assumptions.

What happened

On Monday 2 November, Lee told the National Assembly that the government would "invest boldly in artificial intelligence and future growth engines". The Seoul Economic Daily quotes him saying the government will put 21.3 trillion won into the three megaprojects and AI investment, "nearly double this year's level". AFP, in a report carried by the Japan Times, describes the figure as covering chipmaking and AI "from data centers to robotics".

The numbers were not a surprise. The Ministry of Planning and Budget laid out the same 21.3 trillion won on 1 September, when the Cabinet approved the draft budget, and the Korea Times reported at the time that the figure was 97.2% above this year's. Monday's speech is the formal presentation to lawmakers, who now have to approve it.

The line items reported from the speech are:

• 2 trillion won to expand chip production capacity, including bringing forward the operation of fabrication plants in the greater Seoul area and building a cluster in the south-west. A new special account for semiconductor competitiveness is meant to give this spending a stable base.
• 2.1 trillion won to build power, water and industrial-complex infrastructure ahead of demand. Lee said the aim is that companies "do not miss their investment windows because of inadequate infrastructure".
• 4.7 trillion won for frontier AI development projects, with the goal of bringing homegrown models to the top tier of global performance.
• 500 billion won for field demonstrations of physical AI in eight sectors, including manufacturing, smart factories and defense, per the Seoul Economic Daily and the Korea Herald.
• 13.8 trillion won for what the government calls the "NEXT 10" strategic technology fields, and a research and development budget that rises by 4 trillion won to a record 39.5 trillion won.
• Training for 2,000 specialists in chip design and regional semiconductor industries.

Background

South Korea is home to Samsung Electronics and SK hynix, two of the largest memory chipmakers. We covered both companies' latest results: SK hynix reported third-quarter operating profit of 83.3 trillion won and Samsung reported an operating profit of 107.4 trillion won. The Korea Herald reports that the government expects total revenue to jump 30.4% to 880.8 trillion won next year, with the outlook resting partly on a semiconductor-driven surge in tax receipts, and projects the managed fiscal deficit to narrow to 0.1% of GDP from 3.9% this year.

The government's own framing, in its September briefing, was that AI and chips are needed to stop "structurally low growth" from setting in as the working-age population shrinks and productivity stagnates.

The numbers

type: bar
title: Selected items in South Korea's 2027 AI and chips plan
unit: trillion won
source: Seoul Economic Daily, Korea Herald (speech of 2 November 2026)
highlight: Frontier AI development
Frontier AI development | 4.7
Power, water and industrial-site infrastructure | 2.1
Chip production capacity | 2.0
Physical AI field demonstrations | 0.5

These items are components of the 21.3 trillion won, not a breakdown that adds up to it; the reports do not itemise the whole figure. Two other numbers frame it: the total budget, 820.9 trillion won, and the megaproject money's growth of 97.2%. Working back from that growth rate, this year's comparable figure is roughly 10.8 trillion won, our own arithmetic rather than a published number.

What it means

For chipmakers. The infrastructure line is the notable one. Fabs and data centers are limited as much by grid connections and water as by money, and Seoul is promising to build those ahead of the companies' investment decisions. Early operation of fabs near Seoul and the south-west cluster would add capacity in Korea.

For AI developers. The 10,000-GPU commitment for a national foundation model is a public commitment to a Korean model "globally competitive" in performance, as Budget Minister Park Hong-geun put it. Whether homegrown models can reach the top tier on 4.7 trillion won of project money is the open question.

For regions outside Seoul. The AI push sits inside a wider regional push. The Korea Herald reports 33 trillion won for regional development, more than double this year's allocation, including subsidies covering up to half of qualifying corporate facility investments outside the capital region and the relocation of 44 central government agencies to Sejong. Lee framed this as a response to "K-shaped growth", where gains concentrate in certain industries, companies and regions. The south-western chip cluster and new data center sites are therefore part of a political argument about where AI-era jobs and infrastructure should be built, not only an industrial one.

For the budget itself. The plan leans on chip-driven tax revenue. If the memory cycle turns, the 30.4% revenue forecast is the assumption most exposed. Opposition People Power Party lawmakers heckled the speech's claim that new bonds would leave "almost no net increase" in outstanding debt, according to the Korea Herald.

What we don't know yet

• How physical AI is funded. The two descriptions differ: Budget Minister Park said in September that 2.6 trillion won would go to physical AI demonstration projects, while coverage of Monday's speech gives 500 billion won for field demonstrations in eight sectors. They may count different things (the larger figure may include other programmes), and we have not seen a document that reconciles them.
• The breakdown of the full 21.3 trillion won. Reports list the main items but not how all of it is divided.
• What the Assembly will change. The budget is a proposal until lawmakers approve it, and the opposition has already contested the fiscal assumptions.
• Which companies get the GPUs and the foundation-model money. The reports do not say.

What to watch next

• The Assembly's budget committee hearings and the 2 December deadline.
• Whether the special account for semiconductors passes as drafted.
• Announcements on the 10,000-GPU programme and which developers take part.
• Samsung and SK hynix capacity announcements in the greater Seoul and south-west clusters.
