The "Magnificent Seven" is literally an AI hierarchy
Nvidia 5T - chip near-monopoly
Microsoft 4T - Copilot (enterprise AI) powered OpenAI
Apple 3.9T - personal AI for 1B+ iPhone/ipod users
Alphabet 3.2T - search AI
Amazon 2.4T - AI infra
Meta .8T - open-source AI
Tesla 1.4T - Optimus robots, robotaxi fleet on Autopilot
Going by how far Google (Alphabet) has sprinted ahead of Amazon it shows how folks don't appreciate the infra or backbone dominance of AWS, which is significant.
Meta also is saved by social media integration - there is "Meta AI" chat on WhatsApp and Facebook. Otherwise investors don't care about open-source. Meta's LlaMA models are actually free unlike GPT, Gemini, etc - with the trivial caveat that you have to download and run on your own cloud.
Tesla is the small boy in the club

But it steals some of the thunder from the private xAI which is playing catchup with the quacky Grok. Optimus and robotaxi is still far off.
