No that’s not a good enough reason, Samsung makes HBM4 too, and has better access to production on their own advanced facilities.
As I already stated, Hynix may have better profits right now, but no doubt Samsung can match that, and when the RAM craze is over, Samsung is in a 100 times better position.

Hynix is not worth more than Samsung in reality, this is just another AI craze without a basis in reality.
