As AI workloads scale, high-bandwidth memory (HBM4) has become a critical bottleneck. Nvidia CEO Jensen Huang confirmed Nvidia will be the primary customer for HBM4 solutions to power its next-generation Vera Rubin architecture. SK Hynix has emerged as Nvidia's preferred partner, reportedly securing 50-70% of anticipated HBM4 orders through a multiyear co-development partnership announced in June, positioning it as a major beneficiary of the memory supercycle.
Axe note: As Nvidia locks in HBM4 memory orders with SK Hynix, South African investors should watch the rand and tech exposure closely.
