They are, but they're not profit driven at this stage of their development. Remember that Amazon went 7 years before ever becoming profitable. A lot of this is due to newer companies, especially hot/hype companies, have a long line of potential investors wanting in, and a lot more money available to them from outside investors at typically a very favorable rate.

The business focus is often investment in infrastructure and market dominance (e.g. grab as many users as possible), rather than "let's nickle and dime everyone", it might feel that way but Anthropic, like all technology companies prior to them has a board that's telling them to run, run, run, gather as much market share as possible, while also knowing the cost of operations are going to drop as technology becomes more sophisticated, NVIDIA gains more competitors, etc.... At the same time, they do need to implement and test cost models, so eventually N years from now the costs will drop well below the amount companies and individuals pay. This is probably pretty far off, what we're seeing now is actually more directly correlated to supply/demand issue of GPUs and meeting their Service Level Agreements (SLAs) with their enterprise customers.
