Arm Holdings (ARM) rose 2.36% on September 9, 2026 — AI infrastructure deal wave lifts chip supply.
What happened
Arm Holdings rose 2.7% alongside the Chip Supply Chain rally, boosted by AI infrastructure deal announcements from peers signaling sustained demand for custom silicon design and architecture licensing.
