Samsung, SK Hynix to Boost 8-Layer HBM4 Supply to Nvidia in H2

This signals that leading memory makers see sustained AI-driven demand for advanced HBM stacks, with 8-layer HBM4 becoming a key near-term battlefield. The ramp matters because it narrows the gap between design wins and actual volume deliveries to Nvidia, potentially easing any supply tightness for next-gen accelerators. Who benefits most is still open, as Samsung and SK Hynix jockey for share in a market where yield and qualification speed decide allocation. The watch point is whether this H2 boost translates into stable pricing or sparks competitive pressure on margins across the memory sector.
