Global Market: Samsung, SK Hynix double down on AI chip boom with massive investment push despite oversupply risks

Samsung Electronics and SK Hynix are embarking on one of the world's largest semiconductor investment drives, committing trillions of won to expand memory chip production as they seek to capitalise on surging artificial intelligence (AI) demand. However, industry experts caution that the aggressive capacity expansion could expose the sector to oversupply risks if AI-related spending slows in the coming years, as per a report by Reuters.

The investment plans received strong backing from South Korean President Lee Jae Myung, who praised the country's leading chipmakers for supporting the government's ambition to strengthen South Korea's position in the global semiconductor industry. According to Reuters, the government aims to double the nation's memory chip production capacity over the next five years by accelerating approvals and construction timelines for new fabrication plants.

Samsung and SK Hynix have pledged a combined investment of around 3,200 trillion won ($2.07 trillion), covering a new semiconductor cluster in the country's southwest along with previously announced projects. The companies also plan to fast-track construction at the existing Yongin semiconductor cluster, reducing development timelines that typically span seven to twelve years.


South Korea has emerged as one of the biggest beneficiaries of the AI investment wave, largely due to Samsung and SK Hynix's dominance in high-bandwidth memory (HBM) chips, a critical component used in advanced AI processors. Investor optimism surrounding the AI boom has also driven sharp gains in the companies' shares this year.

The expansion comes amid robust demand from AI hyperscalers and technology companies seeking additional memory chips, resulting in a global supply shortage. However, analysts note that semiconductor fabrication plants require years to become operational, meaning much of the additional capacity is unlikely to come online until the next decade.

Market observers have warned that memory chip prices remain highly sensitive to the balance between demand and supply. While current shortages continue to support prices, a slowdown in AI infrastructure spending could leave manufacturers with excess production capacity.

Some industry experts also believe the scale and speed of the investments raise concerns. According to Reuters, analysts and academics argue that long-term demand remains uncertain, making capital allocation decisions particularly challenging despite today's favourable market conditions.

The aggressive investment strategy marks a notable shift from the cautious approach both companies adopted after previous industry downturns. The memory chip business has historically experienced sharp boom-and-bust cycles, with falling prices contributing to significant financial losses for both Samsung and SK Hynix during earlier market slumps, as per a Reuters report.

Recent profitability has been driven by the AI boom and a sharp rise in memory chip prices following supply shortages. Encouraged by the government's semiconductor strategy and growing global demand, both companies have now opted to accelerate capacity expansion.

Nevertheless, analysts believe the manufacturers are unlikely to repeat mistakes from previous cycles. Samsung has indicated its long-term investment plans remain flexible and could be adjusted depending on market conditions, while SK Hynix has also suggested future spending will be guided by demand trends.

South Korea's government has pledged to expedite regulatory approvals and infrastructure development to complete the country's new semiconductor cluster before President Lee's term ends in 2030, viewing the project as central to its ambition of becoming one of the world's leading AI and semiconductor powers.
