Not Nvidia. Not Micron. This Under-the-Radar Artificial Intelligence (AI) Chip Stock Could Be the Biggest Winner in 2027.

Nvidia (NASDAQ: NVDA) and Micron Technology (NASDAQ: MU) are two of the stock market's biggest artificial intelligence (AI) success stories. Nvidia dominates AI accelerators, while Micron is benefiting from extraordinary demand for memory chips. Both companies have delivered remarkable growth, rewarding investors who recognized their opportunities early.

But as Wall Street looks toward 2027, another semiconductor stock could be preparing for its breakout moment. Marvell Technology (NASDAQ: MRVL) has already rallied on enthusiasm surrounding custom AI chips and advanced networking.

Missed Nvidia in 2009? This Rare Signal Is Flashing Again. In 2009, a "Double Down" signal flashed for a little-known chipmaker called Nvidia. For the first time in years, that same "Total Conviction" signal is flashing for a company 1/100th the size of Nvidia. Continue »

However, the company's latest investor day projections, a lucrative partnership with Nvidia, and an expanding relationship with Alphabet suggest something more substantial than hype. As investors look beyond the obvious AI winners, Marvell could attract considerably more attention.

Marvell covers two enormous AI markets

Marvell isn't trying to replace Nvidia's GPUs or compete with Micron's memory solutions. Instead, the company focuses on two increasingly important components of AI infrastructure: custom silicon and high-speed connectivity.

Custom accelerators allow hyperscalers to design processors specifically optimized for certain workloads. Meanwhile, optical networking and interconnect technologies help move enormous quantities of data between chips, servers, and data centers.

During its recent investor day conference, Marvell estimated its total addressable market (TAM) could approach $400 billion by calendar 2030. Management outlined approximately $37 billion in interconnect revenue and roughly $30 billion from custom silicon by fiscal year 2031. This forecast reflects expectations for annualized growth of approximately 65% and 80%, respectively, across the two businesses.

Nvidia and Google endorsed Marvell

Back in March, Nvidia invested $2 billion in Marvell. The deal helped establish a strategic partnership focused on connecting custom AI processors with Nvidia's computing and networking ecosystem. The relationship focuses on NVLink Fusion, which allows AI developers to integrate specialized processors into Nvidia-based racks.

This is important because it positions Marvell as a beneficiary of the broader data center build-out rather than simply a competitor to Nvidia. Nvidia CEO Jensen Huang's willingness to invest in Marvell provides a meaningful endorsement of its technology.
