South Korea pledges $576B AI chip investment push

South Korea has unveiled sweeping plans to invest more than $576 billion over several years to expand AI and semiconductor production, with President Lee Jae Myung calling the new fabs a “triple axis” for the country’s AI future. Samsung Electronics and SK Hyn

For the second time in a week, a promise was made on live television. This one came with a number so large it sounded like a headline of its own: more than $576 billion.

South Korea rolled out sweeping chip and AI mega-projects on Monday as President Lee Jae Myung pledged to cement overwhelming industry leadership through investments worth more than $576 billion over several years. The announcement was Lee’s boldest push yet to align South Korea’s AI and chip ambitions with a stated goal of narrowing regional disparities and reviving economies beyond the Seoul metropolitan area.

Lee stood alongside the leaders of Samsung Electronics and SK Hynix, the world’s two largest memory chipmakers, for the televised event.

“We must secure the core elements of AI faster than any other country,” Lee said. “Semiconductors, physical AI, and AI data centres are the triple axis for our great leap forward.”

The plan puts major weight on manufacturing scale. Samsung and SK Hynix will invest 800 trillion won ($517.87 billion) with suppliers to build two new chip fabrication sites each in South Korea’s southwest region, Lee said.

The push is not limited to factories. Lee said South Korea’s southwestern city of Gwangju and South Jeolla province will also invest 5-20 trillion won in the projects. He added that a further 81 trillion won is expected for a chip packaging cluster in the Chungcheong area near Seoul.

Lee framed the southwest as both a growth engine and a practical solution to rising demand. He said the region will host major chip production clusters, drawing on abundant, underused power.

“To meet the rapidly increasing demand for semiconductors, we need to quickly complete the production hubs that are currently under construction,” Lee said.

He also pointed to pressure from capacity limits closer to Seoul. “At the same time. we must secure overwhelming production capacity in advance through large-scale new investments. including in the southwestern region. Existing sites centred around Yongin and Pyeongtaek have already reached their limits.”.

The underlying stakes are clear in what the chips are for. High-bandwidth memory chips produced by Samsung Electronics and SK Hynix have become pivotal in the global race to build advanced AI systems. Both companies already operate major semiconductor facilities in and around the Seoul metropolitan area.

The sequence of decisions is part of the pitch: build more capacity farther from the capital, complete what is under construction, and add packaging infrastructure near Seoul. It is a way to keep the expansion linked to AI demand while addressing the political goal of spreading development.

But the plan also runs into the hard realities of building new cutting-edge manufacturing. Industry experts say diversifying chip investment beyond Seoul could ease infrastructure bottlenecks. At the same time. they warned that building cutting-edge fabs requires vast electricity and water. advanced logistics. deep supplier networks and highly skilled labour. They cautioned that these elements may not scale quickly enough in a new region to meet surging AI demand.

In other words, the promise is expansive—while the timeline for making everything work in a new geography will be the true test.
