AMD’s latest 13F filing reveals a 65,516-share stake in Marvell, initially valued at 6.5million∗∗andnowworth∗∗6.5million∗∗andnowworth∗∗10.7 million. This follows Nvidia’s $2 billion strategic investment in Marvell announced in March 2026, making Marvell a focal point of the AI compute chain.

Under the Nvidia deal, Marvell will deliver custom XPU chips and develop NVLink Fusion-compatible scale-out networking solutions, enabling AI ASIC customers to seamlessly integrate with Nvidia GPUs, LPUs, and storage. The two will also collaborate on 5G/6G AI-RAN, silicon photonics, and advanced optical interconnects.

Marvell’s transformation began in 2018 with a series of precision acquisitions:

• $6B Cavium (multi-core CPU, networking) – entry into cloud/5G

• Avera Semi – ASIC customization for hyperscalers

• $10B Inphi (high-speed optical interconnect) – solving AI data bottlenecks

• Innovium – cloud switch chips

• $5.5B Celestial AI (Photonic Fabric) – breaking the memory wall with optical I/O

• Polariton Technologies – plasmonic modulation for 3.2T+ optics

Marvell has evolved from a storage controller vendor into a data infrastructure architect for the AI era, controlling three cores: optical conversion, high-speed switching, and custom silicon. It enables the data highway for AI clusters.
