Marvell's Lumentum Buy Threatens Broadcom's AI Optics Lead, Says TrendForce

What happened

TrendForce said Marvell Technology's planned acquisition of Lumentum could combine optical and electronic capabilities. TrendForce estimates Marvell ranks fourth and Lumentum eighth by revenue in semiconductor wired communications. A combined share would approach 7%, behind only NVIDIA and Broadcom.

Confirmed

Global impact / market context

Buying Lumentum would give Marvell optical parts know-how to pair with its own chips. TrendForce says that could create a stronger rival to Broadcom in AI optical links. NVIDIA and cloud providers could then have another supplier, reducing reliance on one vendor.

Analyst inference

Broadcom leads with switch chips, digital signal processors and lasers that turn electrical signals into light. TrendForce sees Marvell positioning early for co-packaged optics, which means putting optical connections directly beside chips to move data faster inside AI systems.

Analyst inference

What to watch

1. TrendForce estimates the combined Marvell and Lumentum revenue share would approach 7%, placing them behind NVIDIA and Broadcom in semiconductor wired communications. Confirmed
2. Watch whether the planned acquisition is completed, which would determine if the combined optical and electronic capabilities TrendForce describes actually reach the market. Proposed
3. Watch whether NVIDIA and cloud providers adopt the combined firm's electro-optical interconnect solutions, since TrendForce ties reduced Broadcom reliance to that sourcing choice. Analyst inference
