Stimulated by positive remarks from NVIDIA CEO Jensen Huang at the Taiwan Computex, Marvell Technology (MRVL.US) surged 33% on Tuesday, closing at $290.79 in after-hours trading, marking the largest single-day percentage gain in the company’s history. The stock also recorded its best four-day performance since 2001. Based on the current market capitalization of approximately $254.38 billion, achieving the trillion-dollar valuation Huang mentioned would imply nearly a fivefold upside.

Huang highlighted that as AI data center scales continue to expand, demand for network infrastructure has surged. Marvell’s technological strengths in optical networking and interconnect products position it as an indispensable partner. NVIDIA has invested $2 billion in Marvell to support customers in developing semi-custom AI infrastructure, a move viewed by the market as a strategic effort to secure demand for future generations of AI processors.
Over the past year, Marvell’s stock has more than doubled, with the growth driver gradually shifting from custom AI chips to network products. In its recent earnings report, the company projected interconnect revenue for fiscal year 2027 to grow over 70%, exceeding its prior guidance of 50%. The expansion of AI data centers has spurred a surge in demand for optical transceivers, with Marvell providing critical digital signal processors. Barclays analyst Tom O'Malley expects the company’s optical networking revenue could grow by as much as 90% over the next two years.
Recently, Marvell announced the $3.25 billion acquisition of optical networking company Celestial AI, and the $540 million acquisition of interconnect technology firm XConn. These acquisitions further consolidate Marvell’s market position in AI data center interconnect solutions. Following Tuesday’s surge, Marvell’s stock has risen 242% year-to-date, reflecting strong market confidence in its future growth potential.
