Micron shares surge nearly 8x in a year as high-bandwidth memory demand reshapes semiconductor cycles and customer agreements.
Micron’s stock rally has lifted its market capitalization above $1 trillion, driven by surging demand for high-bandwidth memory (HBM) in AI infrastructure. The company’s shares have climbed nearly 8x over the past year, outpacing broader semiconductor peers.
Historically, memory chips like DRAM followed boom-and-bust cycles every three to four years. This cycle differs as AI customers secure multi-year supply deals, and hyperscalers dominate demand. HBM is now tightly integrated with AI accelerators, reducing its commodity-like volatility.
The shift raises questions about whether structural changes will sustain growth or if cyclical patterns will reassert. Investors weigh the durability of these trends against traditional industry dynamics.
