The Chips Are Falling
Sometimes in tech, momentum shifts quickly. This week, Marvell Technology Inc (MRVL) learned that lesson the hard way. Broadcom Inc (AVGO) has grabbed the spotlight after reports surfaced that Microsoft Corp (MSFT) is discussing future custom AI chip designs with Broadcom—a potential blow to Marvell's hyperscaler ambitions. Meanwhile, Marvell is dealing with growing concerns about losing contracts with some of the biggest names in cloud computing.
Marvell's stock dropped roughly 10% by 11 a.m. ET on Monday following a report from The Information that Microsoft might be shifting its custom-chip work away from Marvell and toward Broadcom. That's not great when your entire growth story depends on winning and keeping these massive cloud customers.
Amazon Deal Goes Sideways
The bad news kept coming. Benchmark analyst Cody Acree downgraded Marvell to Hold, citing confidence that the company has lost Amazon.com Inc (AMZN)'s Tranium 3 and 4 chip programs to Taiwanese competitor Alchip. According to Acree, this setback likely explains why Marvell is projecting only 20% XPU growth in 2026—a figure that looks more like slowing momentum than temporary turbulence.
Marvell insists it won't see a revenue drop next year, but analysts aren't entirely convinced. The theory? Any revenue stability might come from lingering Tranium 2 production rather than successfully transitioning to the newer chip generations.
Broadcom's Quiet Expansion
While Marvell scrambles, Broadcom is doing what it does best: quietly tightening its grip on the custom-chip market. The Microsoft discussions reinforce Broadcom's longstanding strength in custom ASICs and networking silicon, where deep enterprise relationships tend to matter more than flashy marketing campaigns.
If Broadcom does land Microsoft's business, it would signal a meaningful shift in how cloud giants think about their vendor relationships—especially at a time when they're reconsidering concentration risks. Microsoft's stock, for what it's worth, was up over 2% by 11 a.m. ET Monday.
Adding to Marvell's challenges, reports suggest the company has been offering fee concessions to secure future chip projects with Meta Platforms Inc (META). That's typically a sign of competitive pressure, not market dominance.
What Comes Next
Marvell's recent acquisition of Celestial AI could still pay off if optical interconnects become the industry standard. The company has innovation on its side. But right now, the market cares less about innovation stories and more about whether you can hold onto your contracts.
In the near-term scoreboard, Broadcom clearly has the advantage. The big question investors are asking: Is this just a rough patch for Marvell, or the beginning of something worse?
