What company is valued at $3 trillion dollars?

I'm curious to know, which company holds the prestigious title of being valued at an astonishing $3 trillion dollars? It's an impressive milestone, and I'm eager to learn about the industry leader that has achieved such a monumental feat. Is it a tech giant, perhaps, or an innovator in a different sector entirely? I'm intrigued to uncover the identity of this colossal corporation and understand what sets it apart from the rest.
