Why is Sandisk outperforming Nvidia in 2026?
Before examining Sandisk’s ascent, investors may find it helpful to understand how Nvidia (NVDA 2.21%) became the leader of the AI processor realm. While Nvidia is a diversified business, its bread and butter is designing graphics processing units (GPUs) — the hardware that provides the key computing power required to develop and deploy AI models.
Over the last few years, hyperscalers like Meta Platforms, Alphabet, Microsoft, Amazon, and OpenAI have collectively spent hundreds of billions of dollars procuring GPUs from Nvidia. As companies accelerate the pace at which they invest in AI, the data workloads involved are scaling at an unprecedented rate.
This is leading to capacity constraints — and as demand for additional cloud infrastructure is on the rise, demand for GPUs and other AI processors is outpacing supply. But as the data center buildout continues, another big bottleneck is forming in the high-bandwidth memory (HBM)…
