Marvell Reportedly in Talks to Buy Lumentum, an $83B Laser Maker

Marvell Technology is reportedly in advanced talks to buy Lumentum Holdings, the maker of optical lasers and transceiver modules for AI data centers, in what would rank among the largest technology deals on record. Bloomberg News first reported the talks on Oct. 28, citing people familiar with the matter, and Reuters carried the report the same day.

Lumentum has a market capitalization of about $83 billion, against about $221 billion for Marvell, TrendForce reported on Oct. 29. That is Lumentum's market value, not an offer price. No price, premium or cash-versus-stock split has been reported, and neither company has confirmed the talks.

Financing is the first question. Bernstein analysts said Marvell may be unable to fund a deal of this size entirely with cash, noting that it held about $3.92 billion in cash and cash equivalents at its latest quarter, according to TrendForce. They also flagged integration risk.

Why Lumentum's Lasers Matter for AI Clusters

The two companies sit at opposite ends of the same link. Lumentum makes the lasers and transceiver modules that turn electrical signals into light between servers and switches. Marvell sells the digital signal processors that drive optical modules, according to its product pages. It also designs custom AI chips for Amazon and Microsoft and has a chip agreement with Google to support its in-house Tensor Processing Units, TrendForce said. Owning a laser supplier would give a chip designer control of a component that AI clusters need in rising volume as they scale out.

Marvell has been building in this direction. Earlier this year it acquired photonics company Celestial AI, gaining its Optical Multi-Chip Interconnect Bridge technology, and TrendForce said a Lumentum deal would fill gaps in its optical component line and strengthen it against Broadcom, its largest rival in custom silicon.

For co-packaged optics (CPO), which move the optical engine next to the switch or accelerator package to cut the power spent on each link, lasers remain a separate supply item. The industry is now writing CPO specifications, while pluggable transceivers keep advancing at 1.6T. A Marvell-owned Lumentum would supply both routes: lasers for CPO and modules for pluggables.

NVIDIA's $2 Billion Lumentum Investment

NVIDIA is both a customer and a shareholder. In a Mar. 2, 2026 release that Lumentum filed with the SEC, NVIDIA said it would invest $2 billion in Lumentum under a non-exclusive, multi-year agreement that includes a multi-billion-dollar purchase commitment and future capacity access rights for advanced laser components.

A deal would put a chip designer that competes with NVIDIA in custom silicon in charge of a laser supplier NVIDIA has funded to expand. How NVIDIA's stake and purchase rights are treated, and how antitrust regulators view the combination, would shape the outcome. None of that has been reported.

What Marvell and Lumentum Have Not Confirmed

The talks are reported, not announced. As of Oct. 29 there was no release or denial from Marvell or Lumentum. A filing or press release from either company would settle the price, the payment mix and the fate of NVIDIA's stake. Until then, the $83 billion figure is a market value, not a bid.
