Qual Watch: All three vendors volume shipping HBM4 for Vera Rubin

Silicon Analysts Weekly for the week of 2026-06-09 to 2026-06-16: Qual Watch: All three vendors volume shipping HBM4 for Vera Rubin. A sourced, provenance-marked briefing on AI-chip supply-chain and pricing movements — HBM spot prices, wafer pricing, foundry and CoWoS capacity, per-chip bill-of-materials cost, and HBM qualification status — derived from public data and human-reviewed. Part of the Silicon Analysts semiconductor data layer.

The take

Vera Rubin is the first NVIDIA GPU generation to enter volume production with all three HBM suppliers simultaneously — SK Hynix, Micron, and Samsung qualified and shipping HBM4 12-Hi. With supply spread across three vendors from day one, pricing leverage shifts decisively toward NVIDIA.

Status changes

SK Hynix × NVIDIA Vera Rubin (HBM4 12-Hi): In qualification → Volume shipping — Jensen Huang confirmed all three vendors qualified and in production as of June 2026. (source · timeline)
Micron × NVIDIA Vera Rubin (HBM4 12-Hi): Qualified → Volume shipping — Micron entered high-volume production of 36 GB HBM4 for Vera Rubin, announced at GTC March 2026. (source · timeline)
Samsung × NVIDIA Vera Rubin (HBM4 12-Hi): Sampling → Qualified — Samsung selected alongside SK Hynix as HBM4 supplier for Vera Rubin as of March 2026. (source · timeline)
