I'd say Amazon had 2 hits - Online retail, and then cloud computing. (AWS is now most of their profit.)
And even Warren Buffett said that it's unusual for a company to succeed in two different areas, yet Amazon did it.
I would say Meta had only one hit -- social networking. Instagram and Whatsapp
were good acquistions, but I think of them more as monopoly plays. Zuck has been investing in VR and AI, looking for the next big thing -- but like Google, he doesn't really know what it is. I'd say it's more driven by a desire to be big and powerful and profitable, than by mission (although of course every case is a mix)
I'd argue that Google also has one hit. Chrome and Android are impressive, but they are not businesses on their own. Self-driving cars didn't turn into a great business.
Google invented transformers, and OpenAI turned it into a product. But neither one got the product + business combo right. OpenAI is very far from profitable, and Gemini looks like a ChatGPT clone to me.
Microsoft is a weird case -- I'd argue that they were second in most of their hits:
- Windows - the GUI desktop was second to Apple
- Enterprise software - Excel was second to Lotus; Word was second to WordPerfect; databases were second to Oracle
- Cloud - Azure was second to Amazon
- Bing - was second to Google
I think Microsoft got to $3T by operational competence -- by cloning and embrace and extend, as opposed to nailing a new hit product + the associated business.
I would give them credit for the early BASIC and OS, but I don't think that's how they reached $3T. Whereas Google basically reached $2T with search+ads, and Meta with social networking.

To summarize my off the cuff theory, which I admit you can poke holes in:
- Apple, Amazon, Nvidia: nailed a hit product + associated business combo TWICE
- Google, Meta: nailed it ONCE (and they are younger companies, so to be charitable, they may not have had time)
- Microsoft: a special case
