New York, May 13, 2026, 11:03 EDT
Marvell Technology surged close to 10% by late morning in New York after a regulatory filing revealed Advanced Micro Devices owned 65,516 shares in the chipmaker at the end of March. It’s a relatively modest stake, but the disclosure grabbed attention given Marvell’s AI data-center hardware profile. According to the filing, the holding was worth $6.49 million at the time. At Marvell’s late-morning level of $180.76, the shares would fetch roughly $11.8 million—if AMD hadn’t changed its position.
The disclosure comes as semiconductor stocks drive much of the U.S. market’s gains. The Philadelphia SE Semiconductor index has surged 64% since late March—far outpacing the S&P 500’s roughly 17% climb. Morgan Stanley Wealth Management’s Steve Edwards called it a “perfect mix” of technical momentum and fundamentals. Meanwhile, BakerAvenue’s King Lip views AI infrastructure as kicking off a “multi-year capex cycle.” Reuters
Even before news of AMD’s stake broke, Marvell was getting plenty of attention. Early Wednesday, Seeking Alpha flagged that the 13F filing had brought new attention to Marvell shares, while TradingKey noted the stock kicked off the session up 3.11%. Investors were sizing up analyst upgrades, a surge in AI networking demand, and Marvell’s role in optical connectivity.
On Tuesday, AMD submitted its 13F-HR for the quarter ending March 31, with CFO Jean Hu’s name on the signature line. The report showed stakes in Sanmina, Absci, and Xanadu Quantum Technologies. But it was the Marvell entry that got traders talking—a rare glimpse at two headline AI chip players, side by side, in a single filing.
Marvell makes custom chips and high-speed interconnects for data centers. These ASICs, or application-specific integrated circuits, target one client or workload, not the general chip market. Back in March, the company forecast fiscal 2028 revenue close to $15 billion—topping Wall Street expectations—and President and COO Chris Koopmans pointed out that their hyperscaler customers are “still growing massively.” Reuters
Analysts joined the action. BofA’s Vivek Arya bumped Marvell’s target up to $200 from $125, sticking with a Buy, after the firm boosted its 2030 AI data-center systems forecast to roughly $1.7 trillion. Over at B. Riley, Craig Ellis went to $205 from $156, also reiterating Buy, pointing to quicker AI spend from hyperscalers and cloud outfits.
The filing doesn’t tell the whole story when it comes to competition. Marvell and Broadcom are both working with cloud providers, helping them create custom processors aimed at cutting reliance on Nvidia’s versatile AI chips. Back in April, Reuters reported Alphabet’s Google was discussing two AI chip projects with Marvell, a move that could see Google diversify beyond Broadcom.
AMD’s been riding the same wave, with its stock touching an all-time high last week thanks to a bullish forecast. Analysts increasingly see the company as a serious contender to Nvidia in the AI chip space. “Success invites competition,” JonesTrading’s Michael O’Rourke said at the time. Matt Britzman from Hargreaves Lansdown called AMD’s story a “broader compute opportunity.” Reuters
The AMD filing only goes so far. A 13F, required from managers overseeing $100 million or more in certain securities, lands 45 days after a quarter ends—so it doesn’t confirm AMD’s current holdings or spell out its buying rationale. Marvell, for its part, isn’t immune to the regular hazards circling AI names: high multiples, pressure from rivals in custom silicon and optics, and the real possibility that top cloud clients start bringing more chip design in-house.
Marvell has been pushing further into optical data centers. In April, the company acquired Polariton Technologies—a firm focused on high-speed, low-power silicon photonics devices—saying the move would help push optical interconnects up to 3.2 terabits and more. Sandeep Bharathi, who leads Marvell’s data-center group, said the deal added “differentiated modulation technology” to Marvell’s optical roadmap. Marvell Technology, Inc.
The real challenge lands later this month. Marvell is slated to release its first-quarter fiscal 2027 numbers after the May 27 close, with its conference call kicking off at 1:45 p.m. Pacific. All eyes are on whether Marvell can translate hype around custom silicon and optical links into actual revenue this quarter—less attention on AMD’s minor stake, more on orders and margins for a stock now driven by AI infrastructure hopes.
