Marvell Technology has experienced a remarkable 241% surge in its share price over the past 12 months, significantly outpacing rival Broadcom's 6.6% gain during the same period. CEO Matt Murphy attributes this growth to the company's decade-long effort to build trust with major hyperscale customers, emphasizing the importance of reliability and credibility in delivering complex chips on time and at scale. Marvell's deepened relationships across the artificial intelligence ecosystem, including major partnerships with Nvidia in March and Google in August, have been pivotal. The company now provides custom silicon to all four major U.S. hyperscalers and sells optical connectivity products broadly across the industry. Data center revenue is projected to rise 60% in fiscal 2027 and 61% in fiscal 2028, according to FactSet. Investors are looking forward to more details on Marvell's long-term financial targets at its investor day in early October [1].
On the broader AI infrastructure front, stocks rallied following significant deal announcements from Qualcomm and Corning. Corning's shares jumped 8% on Tuesday, bringing its year-to-date gain to 90%, after announcing a multibillion-dollar partnership with Verizon to build fiber-optic cables for AI connectivity. This follows a similar multibillion-dollar deal with Amazon in June and a $3.2 billion investment commitment from Nvidia to build new fiber-optic manufacturing facilities. Qualcomm disclosed that it issued warrants to Amazon, allowing the latter to acquire up to $4 billion worth of Qualcomm stock. This is part of a larger agreement in which Amazon Web Services will purchase up to $60 billion worth of Qualcomm's server chips and technology. Qualcomm CFO Akash Palkhiwala stated that revenue from manufacturing chips for Amazon will begin in the December quarter and will be crucial in achieving the company's $15 billion data center revenue target for fiscal 2029 [2].
The positive sentiment extended to other AI-related stocks, with Intel and Advanced Micro Devices gaining 9% and 6% respectively, Hewlett Packard Enterprise up 8%, and photonics company Coherent rising 7%. HPE and AMD have more than doubled in value this year, while Intel has nearly tripled, reflecting the expanding AI infrastructure buildout beyond Nvidia. AMD CFO Jean Hu projected that the total addressable market for semiconductors will reach $3 trillion by 2030, up from CEO Lisa Su's July estimate of $2 trillion by 2028 [2].
Despite the market enthusiasm, there are emerging risks. A May 2026 Gallup poll found that 71% of Americans oppose data centers being built in their communities, a sentiment that Anthropic plans to cite as a risk factor in its forthcoming IPO prospectus [2].
Marvell's CEO remains confident in the company's competitive position, even as Amazon announced a new partnership with Qualcomm. Murphy emphasized Marvell's broad engagement across all U.S. hyperscalers and the entire AI ecosystem, describing the company as 'the Switzerland of this entire market' [1].
CONCLUSION
Marvell's exceptional share performance and strong relationships with hyperscalers underscore its pivotal role in the AI infrastructure boom. Meanwhile, major deals by Qualcomm and Corning have fueled a broader rally in AI-related stocks, reflecting robust investor confidence in continued data center spending. However, rising public opposition to data center construction presents a potential headwind for the sector.
