South Korea's next AI infrastructure push is being measured in hundreds of billions of dollars, with Samsung Electronics and SK Hynix at the center.

CoinDesk reported that the two chipmakers plan to invest roughly 800 trillion won, or about $518 billion, in new factories and packaging capacity tied to artificial-intelligence chips. The report said the money would go toward four fabrication plants in the southwest and a packaging cluster in central South Korea, extending the country's role in high-bandwidth memory and advanced semiconductor supply chains.

Reuters, citing local media before the official rollout, described an even broader Samsung Group plan of about 1,000 trillion won over a decade. That framing includes AI data centers, batteries and displays alongside semiconductor capacity, which helps explain why headline totals differ across reports. The common thread is clear: South Korea wants AI-driven chip demand to support industrial investment beyond the Seoul region.

The move matters because AI models are increasingly constrained by memory bandwidth, packaging and power infrastructure rather than software alone. Samsung and SK Hynix already sit near the center of the HBM market, and further domestic capacity could reinforce that position if execution keeps pace with demand.

For crypto markets, the comparison is less flattering. The same pools of risk capital that chased digital-asset infrastructure in earlier cycles are now watching governments and chipmakers commit far larger sums to AI hardware. That does not end crypto infrastructure spending, but it shows where strategic capital is moving in 2026.
