On June 2, Jensen Huang turned to Matt Murphy on a Computex stage in Taipei and called Marvell the next trillion-dollar company. The stock rose 32.52% that day, its largest single-session gain on record, adding roughly fifty billion dollars in market value before the close. Every desk on the Street ran the clip. Almost none of them ran the number underneath it.

The number was disclosed six days earlier, on the May 27 fiscal first-quarter call, and it carried no theater at all. Marvell raised its forward guide by roughly five billion dollars and lifted interconnect growth from 50% to over 70% year over year. The trillion-dollar line moved the tape. The guide raise moved the thesis. Those are not the same event, and conflating them is how investors end up paying for sentiment while telling themselves they bought fundamentals.

When Jensen Huang stood onstage with Matt Murphy at Computex in Taipei and called Marvell the next trillion-dollar company, the market did not treat it as a courtesy. The stock posted its largest single-day gain on record, jumping more than thirty percent the following session. Endorsements from rivals are usually cheap. This one was not, because Huang was not flattering a partner. He was describing the part of the AI buildout he understands better than anyone, and naming the company that owns it.

Lumentum (NASDAQ: LITE) and Coherent (NYSE: COHR) are the two Western names every AI-optics conversation eventually circles back to. Both have been pulled out of telecom-cyclical obscurity and re-rated into large-caps by the same force: NVIDIA’s data-center buildout and its need to move colossal amounts of data between accelerators with optics instead of copper. Both took a $2 billion equity investment from NVIDIA in March 2026, the identical capital-plus-purchase-commitment template, on the same day the company committed to locking in its photonic supply chain.
