South Korea Accelerates Chip Investment Plans with Samsung and SK Hynix

TLDR

• South Korea’s government is in talks with Samsung and SK Hynix on large-scale semiconductor investments
• A new chip cluster announcement is expected soon
• AI demand could push construction timelines forward by over 10 years, to 2034–2035
• SK Hynix became South Korea’s most valuable company on June 22, hitting a $1.35 trillion market cap
• The Honam region, including Gwangju, is being considered for new packaging facilities

South Korea’s government is in active talks with Samsung Electronics and SK Hynix over a major new phase of chip investment. A presidential policy adviser confirmed the discussions, with a formal announcement on a new semiconductor cluster expected soon.

Presidential adviser Kim Yong-beom described chip demand from the AI industry as “exponential and explosive.” He said this growth could require the two companies to speed up construction of new chip facilities by more than 10 years, targeting completion in 2034–2035.

A National Push for Semiconductor Capacity

The talks go beyond simple factory expansion. The government is focused on balanced regional growth, with the Honam region flagged as a potential location for new facilities. Gwangju is specifically being looked at for chip packaging operations.

This signals that officials want the economic benefits of a chip boom to spread across the country, not just concentrate in existing tech hubs.

SK Hynix is already well ahead. In February 2026, the company announced a $15 billion investment in new semiconductor facilities. That commitment now appears to be part of a much larger national framework, one that could involve hundreds of billions of dollars in total spending.

SK Hynix Hits a Milestone

On June 22, 2026, SK Hynix became South Korea’s most valuable publicly traded company. Its market cap reached approximately $1.35 trillion after shares surged 5.6% in a single session.

The driver behind that rise is high-bandwidth memory, or HBM. These are specialized chips used in AI training and inference. SK Hynix has built a dominant position as a supplier in this category.

Samsung is also part of the conversation, though the company did not respond to requests for comment at the time of reporting.

South Korea’s move comes as the United States, Japan, and the European Union have all launched their own semiconductor subsidy programs in recent years. Each country is trying to reduce reliance on concentrated chip supply chains.

The acceleration of South Korea’s cluster timeline, pushed forward by more than a decade, reflects how seriously the government is treating the current AI-driven demand surge.

Both Samsung and SK Hynix are central to that strategy. An official announcement is expected in the coming days.
