# Why Qualcomm (QCOM) fell 2.76% on October 29, 2026

Qualcomm (QCOM) fell 2.76% on October 29, 2026 — Chip Supply Chain selloff drags Qualcomm lower.

## What happened

Qualcomm fell about 2.8% as the Chip Supply Chain group sold off after Alphabet's results revived fears about AI spending.

## Why it moved

Lighter capex from a major hyperscaler signals softer demand for AI-related chips, and Qualcomm is exposed to that same chip cycle. The shared demand outlook pushes the whole group lower, including Qualcomm.

## Why it matters

Qualcomm is in the Chip Supply Chain theme, which has ridden the AI build-out and hyperscaler capex for months. The theme is now being tested by investor doubts about whether that spending will keep rising.

## What would break the thesis

If hyperscaler capex plans are reaffirmed or raised, the spending worry fades and Qualcomm should recover with the group. A sustained cut in capex from major customers would confirm a broader slowdown in the chip cycle.
