Marvell’s stock responded the way you would expect when the most influential person in AI hardware gives a chipmaker that kind of public endorsement. Shares surged as much as 30%, touching a record high and lifting the company’s market value to around $254 billion at peak gains.

Huang’s endorsement was not just about Marvell. It was a thesis statement on the next stage of AI infrastructure, where custom chips, high speed networking, and optical components become critical to scaling AI data centers.

The market heard the message loud and clear. Lumentum shares climbed about 13%, while Coherent jumped around 17%. Both companies make optical networking components tied to the same AI infrastructure buildout Huang was championing.

Nvidia invested $2 billion in Marvell on March 31 as part of a strategic partnership focused on NVLink Fusion, custom XPUs, scale up networking, and silicon photonics. 

Marvell’s technology is built for the data movement problem sitting at the center of AI infrastructure. As AI systems scale, data centers need faster ways to move information across chips, racks, and networks while keeping power consumption under control. Bandwidth and efficiency are now two of the most important currencies in AI infrastructure.

The June 2 surge did not come out of nowhere. Marvell’s stock had already more than doubled this year before Huang’s comments, helped by investor demand for AI infrastructure names and optimism around its Nvidia partnership.
