The milestone came after a sharp stock surge driven by strong investor enthusiasm for artificial intelligence-related demand. Micron’s shares have risen significantly since late 2025, reflecting growing global demand for memory and storage chips.

Micron is one of the world’s largest producers of DRAM and NAND flash memory, alongside competitors such as Samsung and SK Hynix.

It also plays a key role in supplying high-bandwidth memory (HBM) used in AI computing systems. Analysts say the company is benefiting from a global semiconductor supply crunch and increased demand for AI infrastructure.
