Shares of SK Hynix tumbled 7.0% to $1,070 on July 24, erasing a sharp rally that had pushed the stock above $1,150 just days earlier, as investors digested the chipmaker's massive new spending commitment alongside a broader technology selloff. SK Hynix Bets ₩7.1 Trillion on AI Memory Supremacy, but a 7% Stock Drop Asks: Is the Spending Too Much, Too Fast?
Shares slid 7.0% to $1,070 as investors weighed SK Hynix's biggest-ever packaging plant commitment against a broader tech selloff driven by fears that AI infrastructure spending is running ahead of returns. The drop followed days of volatile swings — the stock bounced from $996 to $1,150 in a single week — exposing how fragile sentiment has become around even the most profitable AI suppliers.
• The Price Tag Is Staggering, Even for a Cash Machine
SK Hynix's board approved ₩7.09 trillion ($5.8 billion) for its next-generation packaging facility in Cheongju , expanding a multi-year project running through 2032 to meet rising AI memory demand and an accelerated cleanroom schedule.
This single allocation covers 37.3% of the total ₩19 trillion budget for the plant — a sum approaching the ₩20 trillion earmarked for a neighboring chip fabrication facility. The company can afford it: cash and equivalents surged to ₩54.3 trillion in Q1, with net cash of ₩35 trillion. But the sheer scale, on top of 2026 total capex set to exceed the ₩30.2 trillion spent in 2025 with no ceiling disclosed , rattles investors worried about returns on every new won spent.
• Record Profits Make the Bear Case Harder — but Not Impossible
Q1 2026 revenue hit ₩52.58 trillion (up 198% year-over-year) with operating profit of ₩37.61 trillion and margins around 72%.
SK Hynix holds the No. 1 global market share in high-bandwidth memory (HBM) — the specialized chips that power AI data centers — at 56.4%. Those economics justify heavy investment. The risk is cyclicality: if AI infrastructure spending slows before 2030, SK Hynix faces overcapacity from aggressive commitments made without disclosed spending limits.
• Supply Constraints Give the Company Cover — for Now
SK Hynix cannot make enough chips to satisfy demand; CEO Kwak Noh-jung has warned that supply constraints for AI memory could persist through 2027.
Chairman Chey Tae-won has said the global chip wafer shortage may last until 2030. That backdrop makes front-loading capacity logical, but it also means the company is making seven-year bets on a demand curve that no one can confidently forecast.
• The Stock's Wild Week Reflects a Market Rethinking the AI Premium The swing from $996 to $1,150 and back to $1,070 in under ten days mirrors the tug-of-war across the sector. Total committed outlays for Cheongju and a new Indiana packaging facility now approach $8.7 billion. Shareholders are no longer asking whether AI memory will grow — they're asking whether the capital required to chase that growth will leave enough profit behind.
