SK Hynix recently surpassed its larger rival as South Korea’s most valuable listed company with a market capitalization of approximately $1.35 trillion. SK Hynix dominates the HBM market that Nvidia and other AI chip designers desperately need.\n\nSK Hynix had already tipped its hand in February 2026, announcing a dedicated $15 billion investment in new semiconductor facilities.\n\nThe new facilities target completion by 2034-2035, which represents a dramatic acceleration from earlier projections that had penciled in a 2044 timeline.\n\n## South Korea’s semiconductor strategy takes shape\n\nPrevious iterations of the plan had estimated total long-term investments at around $471 billion, with approximately $261 billion in private funding, stretching through 2047. The new $646 billion figure suggests the scope has expanded considerably as AI demand projections have grown.\n\nSamsung and SK Hynix together hold a dominant share of the global HBM market, the segment of memory chips specifically designed for the massive parallel processing that AI models require.\n\n## What this means for investors\n\nSK Hynix’s ascent to South Korea’s most valuable company reflects a market repricing that values HBM expertise above Samsung’s far more diversified business, which spans smartphones, displays, and consumer electronics.\n\nThe risk, of course, is cyclicality. The 2034-2035 target completion date means these facilities will need AI demand to remain robust for the better part of a decade. Investors should watch whether these commitments come with government backstops or whether Samsung and SK Hynix are shouldering the capital risk alone.\n\n**Disclosure:** This article was edited by Editorial Team.
