Apple

Apple remains one of the world's most valuable companies, worth around $4.9 trillion, and the reason isn't the iPhone alone anymore -- it's the ecosystem built on top of it. Services (the App Store, Apple TV+, Apple Music, iCloud) now bring in more than $100 billion a year at gross margins north of 70%, turning a hardware company into something closer to a subscription business with a very good phone attached. That shift, more than any single product launch, is what's kept Apple near the top of this list.
