Micron, the only U.S.-based high bandwidth memory manufacturer, reached a $1.27 trillion market cap after reporting Q3 gross margins of 84.6% and Q4 revenue guidance of $49-51 billion, as AI server demand creates unprecedented pricing power in the historically cyclical memory market.

Claims
- Micron's Q3 revenue reached $41.46 billion with 84.6% gross margins, and Q4 guidance of $49-51 billion reflects sustained AI-driven memory demand.
- AI servers require large amounts of HBM, DRAM, and NAND alongside every GPU, making memory a critical and constrained AI infrastructure component.
- SK Hynix leads the HBM submarket with 58% share in Q1 2026, while Samsung and Micron each hold 21%.
- The top three DRAM manufacturers—Samsung at 38.5%, SK Hynix at 28.8%, and Micron at 22.4%—control approximately 90% of global DRAM revenue.
- Micron has signed 16 strategic customer agreements worth $22 billion using deposits, pricing floors, and take-or-pay terms to stabilize the historically boom-bust memory cycle.
Key quotes
Memory has usually been a boom-bust business because factories take years and billions to build, then prices collapse when too much supply arrives.
HBM stacks multiple DRAM dies vertically and places them very close to the GPU through advanced packaging, which creates a much wider data path.
Micron's case got stronger after Q3 revenue hit $41.46B, gross margin reached 84.6%, and Q4 guidance moved to $49B-$51B. Current market cap ~$1.27 trillion.
