# Why Broadcom (AVGO) fell 3.24% on August 20, 2026

Broadcom (AVGO) fell 3.24% on August 20, 2026 — Marvell gains on Google AI networking share loss.

## What happened

Broadcom fell 4.2% after market analysis showed Marvell securing increased share of Google's AI networking and custom silicon orders—a direct loss of business from Broadcom's key hyperscaler customer.

## Why it moved

Google diversifying its silicon suppliers away from Broadcom pressures AVGO's AI-networking revenue and custom-chip margins; loss of a top-3 customer can compress the company's growth rate and profitability mix,…

## Why it matters

AI Compute is Broadcom's largest growth driver, and hyperscaler concentration risk is the key vulnerability; Marvell's penetration proves that Broadcom's dominance is not locked in, and competitive pressure can erode…

## What would break the thesis

If Google keeps Broadcom as the primary supplier or share loss proves immaterial to total revenue, the thesis breaks; any sign of volume recovery or new large-customer wins could restore confidence.
