Arm Holdings (ARM) shares surged to an all-time high of $306.51, wrapping up a spectacular weekly rally of nearly 50%. The momentum was supercharged by Bernstein initiating coverage with an Outperform rating and a $300 price target. Analysts emphasized that Arm sits at the center of a CPU renaissance as AI workloads transition to power-efficient architecture for inference. Nvidia's blowout earnings further validated this AI hardware supercycle, highlighting immense demand for its next-generation Vera CPU built on Armv9. This outlook, paired with Arm's own $2 billion in committed orders for its proprietary AGI CPU, triggered a massive valuation rerating.
