# Why Arm Holdings (ARM) fell 2.12% on September 1, 2026

Arm Holdings (ARM) fell 2.12% on September 1, 2026 — MediaTek's $3.5B Nvidia deal intensifies chip competition.

## What happened

Arm sold off 2.1% alongside the Chip Supply Chain selloff, as MediaTek's $3.5 billion Nvidia AI chip deal signaled accelerating competitive pressures and slowing foundry capex across the semiconductor ecosystem.

## Why it moved

Arm licenses its CPU and GPU architectures to chipmakers; slower fab buildout and wafer-process orders mean fewer new silicon designs entering production, reducing Arm's royalty visibility as foundries moderate…

## Why it matters

Chip Supply Chain theme: fab capex and wafer-process equipment orders have stalled after the AI buildout peak, with foundries and legacy chipmakers cutting spending—reducing the flow of new designs and the licensing…

## What would break the thesis

If AI inference demand accelerates or new edge computing verticals drive design wins, the royalty headwinds ease; sustained capex moderations across foundries would extend the pressure on Arm's growth.
