Marvell Technology has been one of the year’s quieter success stories in the semiconductor space, doubling in value since early February without generating quite the same volume of conversation as its more famous peers. Today changed that.
Shares of the chip designer hit an all-time high of $192.15 on May 14 after reports emerged that Marvell may be developing custom AI chips for Alphabet, the parent company of Google. The stock closed at $188.32, up 5.83% on the day, with a market capitalization of $163.38 billion. Three factors help explain what pushed Marvell to a record high: 1) the Google partnership reports, 2) a wave of analyst upgrades and a notable stake purchase by a major peer, and 3) the broader AI infrastructure tailwinds lifting the entire sector.
The Google rumor that changed everything
Reports surfaced that Marvell may be working on multiple AI chip projects for Alphabet, including an inference-optimized Tensor chip and a memory processing unit. The company has not officially confirmed the relationship, but the reports alone were enough to send the stock sharply higher.
If the partnership is real and expands over time, it would represent a significant new revenue stream for a company that has built its business around being the custom chip supplier that hyperscale technology companies turn to when off-the-shelf products will not meet their needs.
Custom AI silicon is one of the fastest-growing parts of the semiconductor market. As the largest technology companies increasingly design chips tailored to specific artificial intelligence workloads rather than purchasing standardized products, the foundry and design partners who help them do that become essential to the entire ecosystem. A confirmed Google relationship would plant Marvell firmly in that category at exactly the right moment.
Why Wall Street is raising its targets
The optimism extends well beyond the Google reports. Bank of America raised its 12-month price target for Marvell to $200, a significant jump from the prior target of $125, while maintaining its buy rating. Goldman Sachs also raised its target, moving from $100 to $125. B. Riley Financial added to the positive analyst sentiment with its own upgrade.
The disclosure that Advanced Micro Devices had acquired a stake in Marvell also contributed meaningfully to the day’s momentum. An investment by a major semiconductor peer carries particular weight in an industry where companies have deep visibility into each other’s technology roadmaps and competitive positioning. AMD buying into Marvell at current levels reads as a strong endorsement of where the company is headed.
Marvell is further benefiting from a strong quarterly report by networking peer Cisco, whose results underscored the health of AI data center infrastructure spending. Taiwan Semiconductor Manufacturing also revised its global semiconductor market forecast to above $1.5 trillion by 2030, a projection driven largely by AI demand, and Marvell sits squarely in the path of that growth as a key supplier of AI networking silicon and optical interconnect solutions.
What comes next and the risks to watch
Marvell’s earnings report on May 27 will be the next significant test for the stock. Investors will be looking for confirmation of the Alphabet relationship and an update on capital expenditure plans. The company spent $354 million on capital expenditures in fiscal 2026, a conservative figure compared to peers and a point of confidence for investors who have grown wary of chipmakers burning through cash ahead of revenue.
The risks are genuine. Marvell’s valuation is elevated, with a price-to-earnings ratio of 61.34 trading well above typical industry averages. The company is also meaningfully reliant on a limited number of hyperscale customers for its custom AI silicon projects, meaning any lost design win could have an outsized impact on results. Geopolitical tensions surrounding U.S.-China trade relations and chip export controls remain an ongoing concern given Marvell’s exposure to the Chinese market.
For investors watching from the sidelines, the May 27 earnings call may well be the moment that determines whether today’s all-time high represents a ceiling or a starting point.
