The acquisition fills several gaps in Marvell's photonics portfolio, including high-performance laser sources, optical transceivers, optical circuit switches, and compound semiconductor manufacturing based on indium phosphide.

The rationale is physics. Copper wiring can carry a 400 Gbps signal only about 1.25 metres, and the reach halves each time per-lane speed doubles. Optics largely escape that limit, carrying signals over kilometres while cutting the power and cooling each rack needs, which matters as Nvidia and AMD build rack-scale systems stitching hundreds or thousands of GPUs into one compute domain.

Power has been the sticking point. When Nvidia launched its first Blackwell racks in 2024, Jensen Huang said optics were avoided because they would have added 20 kW to a system already drawing 120 kW. Since then Marvell has bought its way into more efficient designs, paying about $3.5 billion for Celestial AI in February 2026, whose near- and co-packaged interconnects use a fraction of the power of conventional pluggable optics.

Notably, Nvidia itself invested $2 billion in Lumentum just eight months ago to expand optics manufacturing capacity, part of what The Register describes as a flurry of investment in optics, silicon photonics and manufacturing. Jensen Huang predicted at Computex 2026 that Marvell's photonics investments would eventually drive a $1 trillion valuation; the company's market cap currently sits around $180 billion.
