HBM Shortage Benefits Micron, Pressures Nvidia in AI Market
A shortage of high-bandwidth memory (HBM) is strengthening the position of Micron Technology while putting pressure on NVIDIA's GPU economics. Chinese AI-chip makers like Huawei and Cambricon are raising accelerator prices due to HBM scarcity, with some models seeing price increases between 20% and 50%. The shortage has made Micron a key beneficiary as its HBM4 is in high-volume production for NVIDIA’s Vera Rubin platform. Micron's strong pricing power stems from the increasing memory content per AI accelerator and constrained supply. Long-term agreements have also helped reduce cyclicality risks, but concerns remain about competitors expanding capacity due to rising prices. For NVIDIA, higher HBM costs could pressure margins or lead to increased system prices despite high demand for its GPUs. Both companies saw improved hedge-fund positioning in Q2 2026, with Micron and Nvidia gaining ownership from multiple funds. The key valuation questions are whether Micron's current earnings represent a cyclical peak or the start of a better memory market regime, while for NVIDIA it is about sustaining exceptional margins as suppliers capture more value.
