Nvidia, Micron, and Sandisk have each seen their stocks rise over 1,000% since the AI boom began, a surge tied directly to exploding demand for data-center infrastructure. The gains, reported by Motley Fool, reflect a semiconductor industry rally that has pushed the sector's market cap from $2.2 trillion in May 2023 to $9.4 trillion in April 2026.
Nvidia was among the first stocks to take off as demand for AI infrastructure exploded after ChatGPT's release, while memory and storage firms Micron and Sandisk rode the second wave. The latter pair has at times outperformed Nvidia thanks to escalating needs for AI data-center memory and storage components, making the rally broader than any single chip designer.
Market pricing currently suggests an 85.5% chance Nvidia becomes the world's largest company by market cap by August 31, 2026. That milestone would cap a run that began with AI infrastructure spending and has since spread across the semiconductor supply chain.
Micron's expansion reflects the underlying demand, with a reported deal adding roughly 300,000 square feet of cleanroom space to support DRAM and high-bandwidth memory production. Those components are essential ingredients powering the AI boom, and the capacity buildout signals sustained demand ahead.
Investors are watching Micron's upcoming earnings report closely, along with any new orders or guidance from Nvidia that could shift its market cap position. Regulatory changes or supply chain disruptions affecting semiconductor production could also influence where Nvidia, Micron, and Sandisk land in the coming weeks.
