# Why Arm Holdings (ARM) fell 8.55% on July 28, 2026

Arm Holdings (ARM) fell 8.55% on July 28, 2026 — China roadblocks hit chip stocks across board.

## What happened

SanDisk and other chip firms hit by China export restrictions, triggering broad chip supply chain weakness.

## Why it moved

ARM's licensing revenue and royalties are directly exposed to SanDisk-like customers' export slowdown and policy uncertainty.

## Why it matters

Across the chip supply chain, infrastructure-layer players like ARM face repricing as China export barriers tighten.

## What would break the thesis

If China restrictions prove narrower than feared for ARM's actual customer base, the sell-off may reverse.
