# SK Hynix

A major South Korean memory chip manufacturer, critical for producing High Bandwidth Memory (HBM) used in AI accelerators. SK Hynix holds ~50%+ market share in HBM for AI GPUs and is a primary supplier to [[entity-nvidia-d50]] and [[entity-amd]].

Highly exposed in the speaker's analysis due to South Korea's reliance on Qatari helium — see [[claim-sk-hynix-vulnerability]] and the [[entity-korea-international-trade-association]] data citation.

**Enrichment context**: South Korean helium imports are ~40–60% Middle East-sourced (with diversification to US/Russia post-2022). SK Hynix reportedly holds 3–6 months of inventory; no HBM production halts have been publicly reported.
