Memory chip stocks are surging, and analysts are pointing to an AI-driven supply crunch that could keep DRAM, NAND, and high-bandwidth memory (HBM) chips in short supply through at least 2028. Several memory stocks have posted year-to-date gains exceeding 100% in 2026, making the sector one of the strongest performers in the broader chip universe.
AI data centers are projected to consume roughly 70% of global memory chip production in 2026. Meanwhile, new fabrication capacity won’t meaningfully come online until late 2027 or 2028. Micron CEO Sanjay Mehrotra said in May 2026 that new industry supply would not significantly ramp up before 2028.
Micron has reportedly sold out its entire HBM supply through 2026. The company and its competitors have locked in buyers with multi-year contracts, essentially pre-selling their output to guarantee revenue streams that stretch well into the future. Goldman Sachs has upgraded key memory stocks, citing the supply-demand imbalance as the primary driver.
The reluctance of top suppliers to invest in expensive new fabrication facilities is creating what analysts describe as a longer and more sustainable market cycle. AI workloads require massive amounts of high-bandwidth memory, and large language models, inference engines, and training clusters represent structurally different demand compared to previous cycles driven by PCs, smartphones, and servers.
