Micron Adds $360B in Market Cap as Memory Index Surges 500%
Memory chipmaker Micron has added over $360 billion in market cap since March 30 as investors broaden the AI trade beyond Nvidia’s GPUs. Bloomberg’s Global Memory Index has surged almost 500% year-to-date and could pressure Nvidia ahead of its May 20 earnings report.
1. Memory Stocks Outpace GPUs
Micron’s stock has climbed more than 12% in a single session, contributing to a $360 billion market-cap gain since the March 30 low as memory suppliers capture AI trade momentum beyond Nvidia’s GPU dominance.
2. ETF Volume Signals Sector Shift
Trading volumes in plain-vanilla and leveraged semiconductor ETFs have accelerated, and multiple issuers have filed for memory-focused leveraged funds, highlighting growing investor demand for high-bandwidth AI infrastructure components.
3. Implications for Nvidia
With Wall Street diversifying into memory and storage plays, Nvidia faces increased scrutiny ahead of its May 20 earnings report, which will test whether AI GPU demand can sustain its market leadership amid broader semiconductor trading dynamics.
