Nvidia, the world's leading AI chipmaker, has invested $2 billion in semiconductor company Marvell Technology as part of a strategic partnership to expand the reach of its AI infrastructure platform, sending Marvell shares more than 9% higher in early trading.
The two companies said they would collaborate through NVLink Fusion, a rack-scale platform that allows customers to build semi-custom AI infrastructure by combining components from multiple manufacturers within Nvidia's broader ecosystem.
Under the arrangement, Marvell will contribute custom XPUs, a category of specialised processors designed for particular AI workloads, alongside NVLink Fusion-compatible networking hardware.
Nvidia will provide supporting technologies, including its Vera central processing unit, ConnectX network interface cards, BlueField data processing units, NVLink interconnects and Spectrum-X networking switches.
The two companies will also collaborate on silicon photonics, a technology that uses light rather than electrical signals to transmit data at high speed, an area seen as critical to reducing the cost and energy consumption of large-scale AI infrastructure.
Marvell chief executive Matt Murphy said the partnership reflected "the growing importance of high-speed connectivity, optical interconnect and accelerated infrastructure in scaling AI."
The deal arrives ahead of Nvidia's GTC 2026 conference, where chief executive Jensen Huang is expected to present the company's next-generation GPU architectures and further ecosystem partnerships, and analysts said the investment validated Marvell's position as a key supplier in the AI infrastructure buildout.
Marvell reported data centre revenue of $1.518 billion in its third fiscal quarter of 2026, representing 73% of total revenue, while Nvidia's fourth-quarter fiscal 2026 revenue reached $68.13 billion, with data centre sales up 75% year on year.
