Micron Technology (NASDAQ: MU) shares fell 2% on Monday. The decline followed reports that competitor Samsung Electronics nears final certification with Nvidia. Samsung seeks certification for its latest HBM4 high-bandwidth memory chips.
This development positions Samsung to potentially ship the next-generation memory first. The memory is crucial for AI accelerators. Competition intensifies in the high-performance computing market.
The news introduces a competitive threat, even as Micron enjoys strong demand for its current AI products. Analysts note Micron is in an "AI super-upcycle." The company's HBM volumes for 2026 are already sold out. Micron increases capital expenditures to expand future supply.
