    Musk Selects Nvidia Rubin Architecture Exclusively for SpaceX and xAI

    Question

    Musk Selects Nvidia Rubin Architecture Exclusively for SpaceX and xAI

    Direct answer

    Elon Musk announced that both SpaceX and artificial intelligence venture xAI will deploy Nvidia hardware exclusively across their computing clusters, standardizing on the next-generation Vera Rubin architecture. The decision excludes competing accelerator architectures from planned datacenter expansions. The public commitment provides visible multi-year hardware demand backing Nvidia roadmap while highlighting persistent procurement preference for Nvidia software ecosystem among hyper-scale model developers.
