Why Qualcomm (QCOM) fell 2.76%
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.
