Marvell Technology shares have retraced to the $240 neighborhood after a 2026 swing that took the stock from an $87 open to a June peak above $300 and a summer selloff that wiped out more than half the gain. The round trip matters because it frames the market's assessment of whether a fabless networking veteran can convert hyperscaler custom-silicon deals into the kind of durable revenue that justifies a tenfold move from here.
The custom silicon pitch
Marvell does not design GPUs and does not run fabs. It sells optical DSPs, Ethernet switches, silicon photonics and, increasingly, application-specific integrated circuits built to order for Amazon, Microsoft, Alphabet and Meta. Those four customers are directing meaningful capital expenditure toward their own accelerators rather than renting every watt from Nvidia and AMD. Marvell's data center segment, which now carries 79 percent of revenue, grew 46 percent year over year in the quarter ended August 1 to $2.1 billion, lifting total revenue 37 percent to $2.7 billion. For the fiscal year ended January 31 the company booked $8.2 billion, up 41 percent, with data center contributing $6.1 billion.
Nvidia's $2 billion vote
In March Nvidia invested $2 billion in Marvell and folded the smaller company's custom XPUs and interconnects into its NVLink Fusion rack architecture. The arrangement lets Nvidia offer a more complete server while Marvell supplies the bespoke silicon and compatible networking. Three months later Jensen Huang described Marvell as "the next trillion-dollar company" at a public event in Taipei. The endorsement is notable because Broadcom currently holds an estimated 80 to 85 percent of the custom ASIC market; Nvidia's check signals that Marvell still has a role inside the GPU giant's ecosystem.
Google's warrant structure
Roughly a month ago Alphabet disclosed a development agreement covering inference accelerators, storage and network controllers, memory interfaces and near-memory compute for its Tensor Processing Units. Attached is a warrant for nearly 59 million shares at $206.58, valued at about $12.2 billion if fully exercised. The warrant vests in 240 equal tranches tied to every $500 million of custom product revenue Marvell generates from Google, implying up to $120 billion of qualified purchases through fiscal 2033. The mechanism effectively pays Marvell to dual-source the silicon surrounding Google's TPUs rather than leaving the entire scope with Broadcom.
What the math requires
A tenfold increase from the current price would value Marvell above $2 trillion. The Google warrant alone contemplates $120 billion of revenue over the next seven fiscal years, a run rate that would need to materialize on top of the existing $8.2 billion base. Nvidia's partnership provides architectural credibility, but the revenue conversion still depends on hyperscalers executing multi-year ASIC programs at scale. The stock's round trip this year shows the market pricing that optionality aggressively, then repricing it, then pricing it again. The next test is whether the warrant tranches start vesting on schedule.
