I feel like Amazon isn't a FAANG anymore. (What's the new A? Anthropic?)
Amazon is successful on the boring utility stuff (logistics, building data centers) but is broadly seen as unable to execute on higher value add things, which keeps it out of the top tier. The AI misses really highlighted that.
It isn’t sexy, but they are selling their proprietary technology to just about everyone. That and their market cap puts them in league with the rest of the big boys.
