# Why Arm Holdings (ARM) fell 7.16% on July 29, 2026

Arm Holdings (ARM) fell 7.16% on July 29, 2026 — China roadblocks hit chip supply chain.

## What happened

SanDisk and other chip stocks have hit China export roadblocks, triggering a broad semiconductor sector selloff that pulls ARM down with the supply chain.

## Why it moved

ARM licenses its designs to chipmakers who depend on China for assembly and sales; export restrictions and demand uncertainty in China ripple upstream to design firms, cutting visibility on royalty streams.

## Why it matters

The Chip Supply Chain thesis is fracturing—geopolitical friction on China is now the dominant risk overshadowing AI tailwinds, and ARM is caught in the sector-wide repricing.

## What would break the thesis

If China export restrictions ease or chipmakers announce alternative supply routes and demand stabilizes, ARM can recover as the long-term AI licensing upside reasserts.
