Why Nvidia just poured $2 billion into AI ASIC competitor Marvell — NVLink Fusion turns into soft ecosystem lock-in

Nvidia has invested $2 billion in Marvell Technology to deepen their partnership through NVLink Fusion, a platform enabling third-party silicon to connect to Nvidia's interconnect fabric. This move aims to generate revenue for Nvidia on every rack deployed, even if Marvell's custom AI accelerators replace Nvidia GPUs. Marvell's ASIC business, focused on custom AI compute, is growing rapidly, with partnerships with major hyperscalers like AWS, Microsoft, and Google. The NVLink Fusion ecosystem is expanding with partners like Samsung Foundry, Arm, and SiFive, while competitors like AMD, Intel, and Broadcom back the UALink consortium as an alternative to NVLink. The collaboration also includes Marvell's acquisition of Celestial AI for photonic fabric tech and a focus on AI-RAN infrastructure for 5G and 6G networks.
