South Korea Launches a $3.5 Billion Fund to Fortify Its AI Chip Supply Chain

SEOUL — South Korea moved on Monday to plug the most vulnerable gaps in its semiconductor empire, unveiling a 5 trillion won ($3.52 billion) fund to bankroll the materials, equipment and chip-design firms that sit underneath its two memory giants — a bet that the country's dominance in the silicon powering artificial intelligence now depends less on the fabs themselves than on the fragile supply chain feeding them.

The fund, announced after a meeting chaired by President Lee Jae Myung, will target "promising materials, parts and equipment firms and fabless companies," Presidential Chief of Staff Kang Hoon-sik told a briefing. The government paired it with a further 5 trillion won in trade financing for export-oriented suppliers and a 10-year, 1 trillion won program to knit together large chipmakers and the smaller vendors that support development, testing and production.

Taken together, the package is an attempt to build a domestic ecosystem beneath Samsung Electronics and SK Hynix — the two firms that together dominate global memory, including the high-bandwidth memory (HBM) stacked alongside Nvidia's AI accelerators. Korea makes the chips the AI boom cannot function without. What it has long lacked is control over the specialty chemicals, photoresists, deposition tools and design IP that go into them, much of it imported from Japan, the United States and the Netherlands.

The vulnerability behind the dominance

Seoul learned the cost of that dependence the hard way in 2019, when Japan restricted exports of three chemicals critical to Korean chipmaking. The new fund is, in part, a delayed answer to that shock — a push to localize the least glamorous but most strategically exposed links in the chain.

The measures are the latest layer of Lee's semiconductor "megaproject" initiative, unveiled in June, under which Samsung, SK Hynix, suppliers and local governments are expected to invest more than $576 billion in new chip-manufacturing projects, concentrated in the country's southwest. The government also said megaprojects worth over 350 trillion won in other regions are due to break ground or expand this year, alongside 57 trillion won in research-and-development projects.

Kang framed the spending as a race against demand the country's existing bases cannot satisfy. The Lee administration has argued that its production hubs around Yongin and Pyeongtaek "will not be sufficient to meet demand driven by artificial intelligence" — an unusually blunt admission that the AI cycle has outrun the plans drawn up only a few years ago.

Permits, power and water as industrial policy

Just as striking as the money was the machinery Lee ordered around it. The government will seek passage of a Mega Special Zone Act within the year to compress permits, environmental reviews and infrastructure construction. Lee, who has made speed a signature demand, instructed the Defense Ministry to relocate functions of a military air base in Gwangju by mid-2028 to clear an 8.3 million-square-meter site for a new chip complex in the Honam region — a cluster Samsung and SK Hynix have pledged to fill with a combined 800 trillion won in investment.

The president has repeatedly cast the effort in the language of national survival. "The world is in the midst of a fierce competition, and an entirely new future is being built around AI," Lee said at a July review meeting on the projects. "We are in an all-out race that will shape the nation's future. In the end, victory will go to those who move first and move fastest."

That impatience extends to the physical inputs. Kang said the government would guarantee power and water on schedule — securing 650,000 metric tons of water a day by 2030 for the southwestern cluster using recycled wastewater and dam supplies, and supplying 14.7 gigawatts of electricity to the flagship Yongin cluster by 2041 through cogeneration, LNG and imported power. Lee, who has complained that Yongin took six years to move from site selection to groundbreaking, told ministries that "investment must never be held up by administrative procedures."

A sovereignty race dressed as industrial strategy

Korea is not acting in isolation. The United States, through the CHIPS Act, Japan through its subsidies to TSMC's Kumamoto plant, the European Union through its own chips act, and China through state-directed funds are all pouring public money into domestic semiconductor capacity. What was once left to markets is now treated as a matter of national security, because the chips that train and run AI models have become the strategic commodity of the decade.

Seoul's twist is to spend on the parts of the chain it does not yet control rather than the fabs it already leads. A dominant position in HBM is worth little if a single foreign supplier of photoresist can throttle output. By financing fabless startups and equipment makers, Korea is trying to convert manufacturing scale into full-stack sovereignty — and to ensure that as AI demand compounds, the value stays onshore.

There is also a fiscal logic. Korea Herald reporting noted that the government intends to draw on stronger-than-expected tax revenue from the chip sector to fund additional support, effectively recycling the AI boom's windfall back into the supply chain that produced it.

What to watch

The decisive tests are procedural, not rhetorical. Watch whether the Mega Special Zone Act clears the National Assembly this year, and how fast the Gwangju air base actually relocates — Lee has benchmarked TSMC's roughly 22-month build in Kumamoto, a pace Korean projects have never matched. Watch, too, whether the 5 trillion won fund produces genuine import substitution in materials and equipment, or simply subsidizes incumbents. And watch the power math: 14.7 gigawatts for a single cluster is a staggering figure that collides with Korea's own energy and emissions constraints. If Seoul can pour concrete as fast as it writes checks, it will have turned its memory lead into something harder to dislodge. If not, the money will have bought announcements, not sovereignty.
