Broadcom Shares Fall as Google Partners With Marvell

Broadcom shares fell 5% on Wednesday, putting the stock on pace for its lowest close since early July, following news that Google has expanded its custom chip partnership with rival Marvell Technology [1]. The move highlights growing investor anxiety regarding the sustainability of the AI hardware trade as major tech firms increasingly diversify their supplier base for custom silicon [1].

Shifting AI Compute Alliances

The decline in Broadcom’s share price coincides with a broader pullback in the chip sector, as the iShares Semiconductor ETF also retreated 2% [1]. Google’s new agreement with Marvell covers a comprehensive range of custom silicon programs that attach to the company's Tensor Processing Unit (TPU) ecosystem, including memory and storage components [1]. While Broadcom has served as a co-designer for Google’s TPUs for approximately a decade, the market has grown concerned that the search giant will drift toward other partners or in-house designs to meet evolving compute needs [1].

Broadcom management has previously acknowledged that Google would likely seek a diversity of sources for its AI compute systems, even while maintaining a substantial supply agreement that runs through 2031 [1]. Despite this, the inclusion of $12.2 billion in stock warrants issued by Marvell to Google has introduced a new competitive dynamic [1]. Analysts note that while some chip firms are using such financing structures to capture market share, Broadcom has historically avoided this approach to prevent shareholder dilution [1].

Market Rotation and Volatility

The pressure on Broadcom is part of a wider trend of volatility within the AI-linked stock group [1]. Recent reports of sluggish revenue growth and widening losses at OpenAI have contributed to negative sentiment, though OpenAI claims its growth rate accelerated in July following the launch of new models [1]. As capital rotates out of the AI buildout, investors have shifted toward healthcare, consumer, and materials stocks [1]. This rotation was recently underscored by the sale of a portion of an Eli Lilly position at record highs [1].

What to watch

• Upcoming Earnings: Market participants are monitoring results from Walmart, Alibaba, Advance Auto Parts, and Deere, all scheduled for release before the opening bell on Thursday [1].
• Economic Data: Weekly jobless claims and the Philadelphia Fed Business Outlook are set for release on Thursday, providing further insight into the macro environment [1].
• Policy Signals: Minutes from the Federal Reserve’s July meeting indicate that several participants view further policy tightening as necessary if inflation does not decline, a factor that could influence future market sentiment [1].

While Broadcom’s long-term revenue targets—projected at $56 billion in AI chip revenue this year and over $100 billion in fiscal 2027—remain formidable, the Google-Marvell deal validates existing concerns regarding potential share loss [1]. Whether Broadcom can maintain its dominant position in the TPU ecosystem without resorting to the aggressive warrant-based financing seen among its competitors remains the central question for long-term investors [1].
