Investor interest in AI stocks, notably Nvidia and Marvell Technology, is peaking with expectations of substantial returns.

Nvidia is currently leading the hardware segment of the AI market, but faces growing competition from AMD, Intel, and various startups.

The big three cloud providers - Alphabet, Amazon, and Microsoft - are anticipated to ultimately dominate the AI industry due to their potential to control the entire AI stack.

Motley Fool highlights Oracle, Taiwan Semiconductor Manufacturing, and Airbnb as three under-the-radar AI stocks poised for significant growth, potentially reaching a $1 trillion market cap.

These companies are well-resourced to build leading AI systems and are backed by numerous model-makers and applications.
