Samsung has yet to receive HBM4 volume-production order from Nvidia, Dealsite reports

Nvidia’s withholding of HBM4 volume orders from Samsung reveals acute concentration risk in the AI memory supply chain. Technically, Samsung’s TSV and advanced packaging roadmaps lack real-world validation without integration into leading AI accelerators, weakening its CoWoS compatibility. On compliance, tightening U.S. export controls on advanced memory could delay Samsung’s shipments despite technical readiness, inflating customer qualification costs. Competitively, SK Hynix leverages its HBM3E lead to deepen Nvidia ties, while Micron accelerates yield ramp with U.S. CHIPS Act subsidies—leaving Samsung vulnerable to marginalization. Over the next 12–24 months, failure to penetrate secondary AI chip ecosystems—particularly those built around Taiwan, China foundries via customized, low-power HBM4 variants—could structurally erode Samsung’s premium memory positioning and trigger a strategic reassessment of its capex allocation.
