Samsung Electronics and SK hynix Will Invest a Combined 800 Trillion Won ($518 Billion) in Building a New Computer Chipmaking Hub in South Korean

South Korean President Lee Jae Myung joined the two chairmen for the announcement, underscoring his broader push to spread investment beyond the Seoul metropolitan area, historically the country’s economic and semiconductor hub.With this landmark announcement, Samsung Electronics and SK hynix are placing one of the biggest bets yet on the AI boom, committing hundreds of billions of dollars, a buildout that is also stoking fears of a painful reckoning should AI spending eventually cool. Under the plan, Seoul aims to double the country’s memory chip production capacity within five years, while Samsung and SK hynix accelerate fab construction at the existing Yongin cluster, compressing what were once 7-to-12-year build timelines. Combined, the two companies have now pledged 3,200 trillion won (about $2.07 trillion), including previously announced projects alongside the new 800 trillion won southwest cluster.

Both companies are responding to two converging forces that together create an enormous business opportunity, and equally enormous pressure: a global memory shortage driven by surging AI hyperscaler demand.

Samsung’s and SK hynix’s memory businesses have turned highly profitable recently, largely on the back of an acute chip shortage that nearly doubled prices in the first quarter alone. The two companies have posted record profits as soaring data-center investment fuels memory demand, and officials expect that demand to keep climbing as AI extends into robotics and autonomous vehicles. Their existing Gyeonggi province complexes may reach capacity sooner than expected, the companies say. Both firms’ dominance in HBM, the specialized chips essential to advanced AI processors, has helped drive SK hynix and Samsung shares up 307% and 179%, respectively, this year.

The project is also a massive logistical undertaking, requiring vast sites along with adequate power, water, and skilled labor; by comparison, it took nine years to build SK hynix’s existing Gyeonggi cluster.

The opportunity is undeniably huge, but it comes with real risks, chiefly oversupply, which could trigger a fresh round of price declines followed eventually by another upturn, in a classic industry cycle. Still, few other players in the world could attempt something on this scale, given that South Korea holds two of the industry’s champions. Ultimately, alongside the opportunity and the challenges, strong government backing remains a key ingredient for this effort’s success.
