Marvell acquires Lumentum to secure AI data center optical connectivity

Marvell Technology agreed to acquire Lumentum on November 2, 2026, paying 4.5 Marvell shares for each Lumentum share to secure production of lasers and optical components for artificial intelligence data centers, according to Stock Titan reporting. The companies stated AI data centers are shifting from copper wires to optical links because AI systems require more bandwidth than copper infrastructure can carry. The acquisition reflects intensifying competition to control supply chains for AI infrastructure components as hyperscale data center construction accelerates.

The deal addresses a critical bottleneck in AI infrastructure: high-speed data transmission between servers and within chips. Optical interconnects can handle higher bandwidth and generate less heat than traditional copper, making them essential for the dense compute clusters required by large language models and other AI workloads. Marvell's move to vertically integrate optical component production signals that semiconductor companies view connectivity as strategically important as compute capacity. The transaction comes as AI infrastructure spending approaches one trillion dollars and companies race to secure supply of specialized components beyond GPUs and memory.
