How Marvell and Lumentum stack up in AI's optical race
ConfirmedShare on
In Short: Marvell Technology and Lumentum Holdings are set to merge in a $115 billion deal, creating a new leader in AI connectivity.
Matt Murphy, Marvell Technology's Chairman and CEO, announced the acquisition of Lumentum during the Marvell Technology Investor Day in New York City on October 6, 2026. The deal, valued at $115 billion, marks the largest merger between two publicly traded companies.
Murphy emphasized the strategic importance of the merger, stating, 'AI connectivity is going to be as consequential as the compute, memory, fab, and IP licensing categories.' He highlighted the unique opportunity to combine Marvell's semiconductor expertise with Lumentum's photonics leadership.
Both companies are headquartered in Northern California and have received 'tremendous support' from hyperscalers, according to Murphy. Nvidia, an AI chip giant, is a strategic investor in both companies and has given 'super positive' feedback on the deal.
The merger aims to create a category leader in AI connectivity by uniting Marvell's semiconductor design capabilities with Lumentum's data-center optics expertise. This combination is expected to address the growing connectivity demands of next-generation AI infrastructure.
Under the terms of the all-stock agreement, Lumentum shareholders will receive 4.5 shares of Marvell common stock for each share held. The deal is expected to generate significant revenue synergies and other benefits.
Lumentum's product pages showcase PAM4 optical DSPs and optical modules, and the company has demonstrated a photonic fabric memory module that links up to 16 GPUs over light. This technology points to Lumentum's focus on optics closer to compute rather than just between buildings.
Despite the aggressive pullback in AI stocks last week, Marvell believes the investment is still warranted. The company expects to outperform as a combined entity, with both companies executing phenomenally well together.
The deal has garnered positive feedback from industry leaders, including Nvidia CEO Jensen Huang, who has expressed support for the merger.
Marvell shares slid more than 1% and Lumentum fell almost 3% after the announcement of the all-stock deal, reflecting investor sentiment.
The merger is expected to create a new standard in AI connectivity, with the companies aiming to define the transition to optical connectivity in AI infrastructure.

What's still developing
- "It's very rare that you can find two companies of the caliber of Lumentum and Marvell that are number one in their respective areas that find a moment in time where you can combine and create a category leader in a new category," he told anchor Liz Claman.
- "We're putting together basically the best-in-class leader in AI connectivity technology for semiconductors with the leader in photonics. And it is something that hasn't been done before."
- "Nvidia is invested in Marvell, Nvidia is invested in Lumentum. We think we can actually bring a lot more product to bear to Nvidia a lot more quickly in this combination," Hurlston said.
- "It’s really a historic day for the two companies," Murphy said.
- Marvell Technology is in advanced talks to buy Lumentum Holdings, Bloomberg reported on October 28, 2026, citing people familiar with the matter.
- That demonstration is separate from the reported talks, and nothing in the record links it to Marvell.
- The Bloomberg headline reads “Marvell Is Said to Near Deal for Lumentum In AI-Related Megadeal.” Three facts sit underneath it.
- The Marvell Lumentum acquisition would join a chip designer with a maker of data-center optics at a moment when AI clusters are straining every copper and fiber link inside them.
- Seeking Alpha’s headline, which said Lumentum jumped on the report that Marvell was in advanced talks, tells us investors treated the story as credible enough to move the stock.
- Benzinga reported that Marvell already buys lasers from Lumentum.
- Marvell said the purchase of Lumentum, which manufactures lasers, circuit switches and other products used for data centers, would make the enlarged company a "category leader in AI connectivity." Marvell, founded in 1995, makes data infrastructure semiconductor products.
- "The companies that move first and help define this transition will set the standard for decades to come." Nvidia earlier this year said it was buying a $2 billion stake in Lumentum.
