Marvell Technology Inc. stock rose about 12% today, recently trading near $325 per share as investors reacted to its upcoming S&P 500 inclusion, stronger AI data center demand, and a major analyst price target hike tied to optical networking.
The stock moved higher because traders were pricing in index-related buying ahead of Marvell’s planned addition to the S&P 500 before the market opens on June 22, while KeyBanc’s new $385 price target gave investors another reason to chase the AI networking story. That combination helped push trading volume above normal levels and sent shares to a new 52-week high of about $330.
Analyst sentiment strengthened after KeyBanc raised its price target on Marvell to $385 from $260 while keeping an Overweight rating. The firm cited growth in optical networking and digital signal processors, which help AI data centers move information between chips and servers at very high speeds.
The business story also supported the rally. Marvell and Tower Semiconductor announced that they shipped over 5 million coherent photonic integrated circuits, which are optical chips that help data centers move huge amounts of information with better speed and power efficiency.
That matters because Marvell is increasingly seen as a connectivity-focused AI winner, not just another chipmaker chasing Nvidia. Nvidia remains the scale leader, with Q1 fiscal 2027 revenue of $81.6 billion, up 85% year over year, while Broadcom reported Q2 fiscal 2026 revenue of $22.2 billion, up 48%, showing how investor attention is spreading across AI compute, custom silicon, and networking.

Under valuation assumptions, the stock is modeled using:
Marvell’s revenue outlook has improved sharply as AI data center spending drives demand for optical interconnects, Ethernet switching, custom silicon, and photonic connectivity.
Those products matter because AI clusters need chips that can move data quickly between processors, servers, and racks without using too much power, making connectivity a key bottleneck as cloud companies build larger AI systems.
CEO Matt Murphy said at the BofA Global Technology Conference that “AI is the market for semiconductors,” and added that Marvell’s data center revenue grew 46% last year, should grow about 50% this year, and currently points to about 55% next year.
Marvell Technology Revenue & Analyst Growth Estimates Over Five Years

Marvell can deliver stronger results if faster 800G and 1.6T optical links scale quickly, custom AI chips expand across more hyperscaler customers, and scale-up optics becomes a meaningful revenue contributor as AI clusters grow larger.
The around 32% revenue growth assumption is aggressive but defensible if AI-related networking demand keeps expanding, while the around 35% margin assumption depends on Marvell scaling higher-value data center products without losing too much profitability to R&D and supply chain costs.
Based on these inputs, the model estimates a target price of around $280, implying about 14% downside from the recent price near $325, which suggests the stock looks overvalued after its sharp rally despite strong business momentum.
At current levels, Marvell’s business story remains compelling, but the stock already reflects a lot of AI optimism, so future performance will depend on whether data center growth, optical connectivity demand, and custom silicon wins can keep pace with the premium valuation.
Investors can estimate Marvell Technology’s potential share price, or what any stock could be worth, in under a minute using TIKR’s New Valuation Model tool.
