Marvell Technology designs semiconductors for data center networking, storage, and carrier infrastructure, and has expanded significantly into custom AI silicon. Its product portfolio includes Ethernet controllers, optical DSPs, storage controllers, and custom application-specific integrated circuits designed for specific cloud hyperscalers building their own AI accelerators. Marvell functions as a design and engineering partner to hyperscalers that want chips optimized for their specific AI workloads rather than the general-purpose GPUs available from Nvidia and AMD.

Hyperscaler custom AI silicon programs have been a major revenue driver for Marvell. Building a custom AI chip requires chip design expertise, advanced packaging, high-speed SerDes IP, and manufacturing relationships to bring a complex multi-die system into volume production—capabilities Marvell has invested in. Its custom silicon programs entered volume production during FY2025, with data center revenue growing 78% YoY in Q4 FY2025. The company's electro-optic interconnect products—used in the optical links connecting AI accelerators—are a second significant growth vector within AI.

Marvell delivered record fiscal 2026 revenue of $8.195 billion, growing 42% year-over-year, driven by robust AI demand. Marvell also expanded its portfolio through acquisitions, picking up Celestial AI and XConn Technologies to strengthen its position in AI scale-up networking and silicon photonics.
