The semiconductor giant Nvidia (NASDAQ: NVDA) is quite the company, developing high-end graphics processing units (GPUs) that help power artificial intelligence (AI) applications. Many investors view Nvidia as the picks-and-shovels play for AI, which would be pretty remarkable given how much AI is expected to change nearly all aspects of our daily lives. With a nearly $3 trillion market cap, Nvidia has grown so big that it has excess resources available to invest in other AI companies that it finds compelling or that it may partner or work with.
