Marvell agrees to buy optical components maker Lumentum in a $115B all-stock deal, as it seeks to rival Broadcom; Nvidia invested $2B in each company in 2026

If you use cloud-based AI services, the cost of high-speed networking may increase due to industry consolidation.

Marvell Technology Inc. is reportedly in advanced talks to acquire Lumentum Holdings Inc., a maker of optical components for data centers, in a potential multi-billion dollar transaction. Bloomberg reported that the deal could be announced as early as the following week, citing sources familiar with the matter. Lumentum, which has an approximate market value of $83 billion, is backed by Nvidia Corp. Marvell, valued at about $221 billion, is seeking to bolster its position in the artificial intelligence sector by scaling up its optical networking capabilities. This potential acquisition, if finalized, would be one of the largest mergers in the tech and telecom industries. The move comes at a time of high demand and scarcity for lasers used in the upcoming optical transition within data centers, with Lumentum's products being particularly sought after.

Marvell's potential acquisition of Lumentum appears to be a strategic move for vertical integration, aiming to control critical components like DSPs and lasers for optical modules. This aligns with a strategy to rival Broadcom's market dominance by consolidating capabilities that were previously sourced externally. While Lumentum's current strong product portfolio and market position might suggest it's an unfavorable time for them to sell, the offer likely represents a significant shareholder value proposition that the board cannot ignore.

This deal signifies a significant push for consolidation in the high-speed optical networking market, driven by the insatiable demand for AI infrastructure. By acquiring Lumentum, Marvell aims to secure its supply chain and gain a competitive edge in providing integrated solutions. Investors will closely watch whether Marvell can successfully integrate Lumentum's operations and technologies, replicating the success of its prior acquisition of Inphi, and if this move will truly challenge Broadcom's established leadership in the long term.
