An inside look at SK Hynix $720 billion AI-fueled buildout that's taking over South Korea

Why it matters

The compute buildout is accelerating beyond GPUs. HBM (high-bandwidth memory) is becoming the constraint, and SK Hynix's massive capex bet signals where the next bottleneck in AI infrastructure will pinch hardest.

Key signals

  • $720 billion capex commitment from SK Hynix
  • Focus on high-bandwidth memory (HBM) production
  • Demand driven by AI model training and inference
  • Exclusive first look at facility expansion
  • South Korea's industrial strategy shift toward AI infrastructure
  • HBM emerging as critical chokepoint in AI hardware supply chain

The hook

$720 billion. SK Hynix is betting its entire future on memory for AI — and reshaping South Korea's industrial landscape to do it.

SK Hynix, the leading maker of high-bandwidth memory, is pouring $720 billion into memory factories to meet AI demand. We got an exclusive first look.
