Overview
- Micron reported that its high‑bandwidth memory (HBM) is sold out through 2027 and that it can meet only about half to two‑thirds of the largest AI customers' HBM demand.
- The company has signed 16 multi‑year take‑or‑pay agreements that carry roughly $100 billion in minimum revenue floors and has collected about $22 billion in deposits and letters of credit.
- Investors have re‑rated memory and storage stocks sharply in 2026, with SanDisk up roughly 650–700% year‑to‑date and Micron rising hundreds of percent, while both trade at compressed forward earnings multiples.
- HBM sits next to GPUs on accelerator boards and directly limits how many finished AI systems can be built, which is why customers and Nvidia have locked long‑term supply commitments totaling hundreds of billions of dollars.
- Analysts warn the rally could reverse if competitors such as Samsung, SK Hynix and CXMT speed capacity builds or if demand or pricing softens, so markets are watching Micron's Sept. 30 report for guidance on margins and contract pricing.
