Elon Musk’s X post on humanoid robot memory lifts Micron stock

Elon Musk posted on X that DRAM needed for humanoid robots will "exceed everything else on Earth," prompting a jump in Micron Technology shares. The comment came after Musk replied to a Citrini Research analyst and highlighted Tesla’s memory cuts for its Optimus robot chips. Micron’s CEO Sanjay Mehrotra said physical AI, including autonomous vehicles and humanoids, could become a major memory driver by decade’s end.

The stock reaction shows investors view the robot memory story as a new growth catalyst for Micron, potentially expanding its addressable market beyond data centers. Analysts have raised price targets, citing tight supply and rising demand for DRAM in physical‑AI applications.
