Yes, it seems very possible to me that Nvidia makes a lot of money. They are literally the largest company in the world.
Who pays? Only all the companies, desperately raising as much capital as possible, issuing new stock to do it, going for unprecedented investment rounds, burning cash reserves to fund the largest data centre rollout in history.
Who builds the things that go into said datacenters? The thing that has also raised in price dramatically in recent years?
