South Korea chip shift moves AI capex focus to tool makers

South Korea chip shift moves AI capex focus to tool makers

SEOUL, July 1, 2026, 05:04 (KST)

  • Samsung Electronics and SK Hynix plan to put 800 trillion won, around $518 billion, into new chip fabs in southwest Korea. The effort is part of a bigger chip push now above $576 billion.
  • ASML Holding jumped 6.79% in Amsterdam on June 30, tacking on around 43 billion euros to its market cap, according to Google Finance data.
  • Order books are clearer for tool makers, but memory makers are seen as more exposed to price swings and oversupply risk.

ASML Holding was the biggest mover after South Korea’s new chip spending news. Shares in the Dutch equipment maker ended up 6.79% at 1,721.40 euros in Amsterdam on June 30. ASML’s market cap hit 675.86 billion euros, Google Finance shows. The gain adds around 43 billion euros to equity value in a day.

That’s a big jump. SK Hynix said in March it made an 11.95 trillion won ($7.97 billion) order for ASML EUV lithography gear, the biggest single order ASML has reported from a customer. The new southwest Korea fab plan comes in at $518.3 billion, about 65 times more than the tool order, though not all fab spending is for lithography.

Samsung Electronics and SK Hynix plan to build two new factories each in the southwest of South Korea, according to statements from both companies. AP reports the pair are responsible for around two-thirds of global memory chip output. The companies didn’t offer a timeline for finishing the new fabs in the southwest.

Tool stocks got an early bump because fabs take time to build and need land, utilities, and a long setup. Orders for tools hit earlier—like ASML’s order in March, which gave investors a number to work with. Bloomberg’s note on Google Finance pointed to ASML and other chip-tool names as the focus of the market’s move on the Samsung and SK announcement.

Memory makers now face being priced on both supply strain and plans for new output. Reuters said South Korea is aiming to double memory-chip capacity in five years and push quicker buildout at the Yongin cluster. Samsung shares surged 179% this year, SK Hynix jumped 307%, both lifted by strong high-bandwidth memory orders.

“Memory pricing is still tied to supply and demand, and if capex speeds up over the next decade, the risk of long-term oversupply grows,” Morningstar’s Jing Jie Yu said. Reuters

Lee Jong-ho, professor at Seoul National University’s Department of Electrical and Computer Engineering, said the investment “could determine a company’s future.” Demand is solid at the moment, but Lee said the outlook over three years is uncertain. Reuters

SK Hynix Chairman Chey Tae-won spelled out the challenge. The project needs “vast sites, along with sufficient power, water and skilled workers,” he told AP, which also noted it took SK Hynix nine years to finish its big Gyeonggi Province cluster. AP News

Nomura’s CW Chung said investing in other regions may help hedge against uncertainty tied to the Yongin cluster. CLSA’s Sanjeev Rana flagged the risk of a memory market downturn, but said producers could scale back spending if there’s too much capacity.

The plan links memory chips to future demand outside data centers. Korean officials told AP they see demand climbing as AI adoption moves into industrial robots and driverless cars. Ars Technica called the policy a $1 trillion effort on memory chips and humanoid robots.

Investors care about the gap between ASML’s 6.79% rise and SK Hynix’s 0.84% move. The tool makers are getting paid on expected orders. Memory makers are pricing in a supply crunch, but it needs to hold for new fabs to pay off.
