Their satellite internet business is the only thing which makes them money, which is enabled by their orbital launch business which is as of right now not profitable and I have no idea of if it ever will be but without it they would not be able to launch enough satellites.
Their stupidity with AI and buying X mostly seems to be about scamming investors to make Musk even richer. Like this particular deal is just them doing what CoreWeave does at a SpaceX valuation.
