Apple

Apple is still the world's most valuable company, worth around $3.5 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 brings 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 at the top of this list.
