Nvidia is aggressively leveraging its massive cash reserves to cement dominance across the entire AI stack, most recently taking a $2 billion stake in networking giant Marvell. For leadership teams, this shift from 'chip sales' to 'ecosystem investment' signals that the AI battleground has moved to the high-speed infrastructure required to keep these systems running.
