Noam Mizrahi has been saying the same thing for two years, and the market has only just decided to believe him. Marvell’s corporate CTO, based at the company’s Israeli site and a Technion graduate, has argued since the early innings of the AI build-out that the constraint on the next leap was never going to be the processor. It was going to be the wire between the processors — and then the optics, when copper ran out of reach. The industry called this a backwater. Marvell bet the company on it. The bet has now compounded into one of the most violent re-ratings the semiconductor tape has produced this cycle.

KeyBanc’s John Vinh raised his Marvell price target to $385 from $260 on Thursday, a 48% increase, and kept his Overweight rating. The headline number is large. The argument behind it is more interesting, because it inverts the hierarchy that has carried the stock for two years.

For most of the AI cycle, Marvell has been priced as a custom-silicon story. The thesis was the XPU pipeline: bespoke accelerators for AWS and Microsoft, a clear line of sight to roughly $10 billion in custom-chip revenue by fiscal 2029, and a seat at the table next to Broadcom in the ASIC duopoly. Networking was the supporting act. Vinh has now promoted it to lead. He came out of recent investor meetings calling networking the most durable growth opportunity Marvell has, and put a number on the scale-up market — optical links, silicon photonics, and high-speed switching — of around $30 billion by 2030.

SanDisk is the reference point that started this. After spinning out of Western Digital in early 2025, the stock bottomed near forty dollars in April of that year and now trades close to nineteen hundred — a forty-five-fold move accomplished in roughly twelve months. It is the kind of chart that sends investors hunting for the next one. But the lesson of SanDisk is easy to misread. It did not climb because of a proprietary technology nobody else had. It climbed because NAND flash entered a brutal undersupply, pricing inflected, and a newly independent company captured the entire swing. That is a commodity supercycle, not a moat. Memory re-rated because the physics of supply and demand turned, and the same mechanism will eventually turn the other way.
