Broadcom's Google Scare: History Says Don't Panic
💡 Key Takeaway
Broadcom's drop on Google's Marvell expansion is likely an overreaction, as history shows design-away scares take years and don't necessarily hurt revenue, but concentration risk in AI warrants caution.
What Happened: Google's Chip Shuffle
On August 19, Marvell Technology announced an expanded custom chip agreement with Google, including a warrant tied to up to $120 billion in future purchases. This news sent Broadcom's stock down about 5% in morning trading, as investors worried that Google, Broadcom's most important custom AI chip customer, was diversifying away.
The market reaction was selective: AMD fell about 4%, Nvidia was flat, and Marvell jumped 8%. This suggests investors were repricing who wins Google's future orders, not fleeing the chip sector entirely.
Importantly, Google hasn't dropped Broadcom. In April, Broadcom announced a new long-term agreement to develop Google's future TPU generations and supply components for AI racks through 2031. The Marvell deal appears to be an addition, not a replacement.
This isn't the first time Broadcom faced a design-away scare. In January 2023, Bloomberg reported Apple planned to drop Broadcom's Wi-Fi/Bluetooth chip by 2025. Apple eventually did, but Broadcom's revenue nearly doubled from fiscal 2023 to 2025, and the stock surged over 500%.
The key difference: the Apple risk was in a mature side business, while Google sits in Broadcom's AI growth engine. Broadcom's AI semiconductor revenue hit $10.8 billion in fiscal Q2 2026, up 143% year over year, and management guided for $16 billion in Q3.
Why It Matters: AI Concentration Risk
This news matters because it highlights Broadcom's concentration risk. Google is a key driver of Broadcom's AI revenue, which is the main growth story. If Google shifts orders to Marvell, it could impact Broadcom's growth trajectory.
However, history suggests these transitions are slow and partial. The Apple precedent shows that losing one chip doesn't mean losing the customer. Broadcom grew straight through the last design-away scare.
The Marvell deal's vesting schedule stretches to 2033, indicating a long-term partnership that complements, not replaces, Broadcom's work. Broadcom's April agreement with Google through 2031 provides some stability.
At 60 times earnings, the market is pricing in high growth. Any sign of slowdown could hit the stock hard, but the current drop may be an overreaction.
Investors should watch Broadcom's AI revenue in upcoming earnings reports for clarity. The evidence will come on earnings days, not in a one-day sell-off.

Bobby Insight
Hold Broadcom if you own it; don't panic sell, but don't buy the dip aggressively given valuation and concentration risk.
History suggests the drop is an overreaction, but the AI concentration risk is real. Broadcom's valuation at 60x earnings leaves little room for error. Wait for earnings to confirm growth before adding.
