Samsung currently leads HBM4 validation due to process improvements enhancing stability. SK hynix retains volume leadership despite re-sampling, while Micron trails slightly. Given robust AI demand and tight capacity, NVIDIA is expected to engage all three suppliers to secure the Rubin platform's supply chain.

Key Highlights

Samsung Leads Validation: Process upgrades have resolved heat issues and improved efficiency, resulting in superior product stability and the fastest validation progress.
SK hynix Retains Dominance: Despite re-sampling, there are no major bottlenecks. Leveraging established partnerships, it is expected to maintain the largest market share.
Micron Trails Slightly: Constrained by its technical architecture, Micron faces a slower validation pace and lower expected market share.
Three-Supplier Strategy: Due to tight memory capacity, NVIDIA will likely adopt all three manufacturers to fully satisfy the massive demand for the Rubin platform.
