Nvidia overtook Apple again to become the world's most valuable again.

On Tuesday, Nvidia shares climbed 2.84 percent, which means Nvidia's market cap rose to $3.43 trillion, followed by Apple with $3.38 trillion and Microsoft with $3.06 trillion.

The thing is, at this rate, sooner or later, Nvidia will overtake Apple and never look back.

This is a company that most people only knew because they made components for gaming hardware, but they found themselves at the right time in the right place.

Nvidia makes components that anyone who wants to build AI stuff needs.

For the time being, Nvidia can choose to buy Apple or Samsung, they can choose to use Amazon and Google or not.

By contrast, Amazon, Google, Apple or anyone who wants a piece of the AI pie, they have to work with Nvidia.
