I don't trust Elon Musk words, at all. It doesn't mean I think it is wrong, but that it can be right or wrong, and material evidence may point to either direction, but what Elon Musk says is random noise to me. At least when he is talking about his business. He is like a professional poker player, you never know when he is bluffing.

In the case of Starlink, on what grounds does it "breakeven"? It is a department of a private company, there is no way to know. In particular, Starlink is entirely dependent on SpaceX launches. How much does Starlink pays SpaceX for its launches? It is a completely arbitrary value. In reality, the money doesn't leave the company.

For what I know, it may just be a pumping scheme for a future IPO, with the goal of eventually funneling investor money from a public Starlink to a private SpaceX. Or maybe not, Elon Musk is way smarter than me when it comes to business, that's why he is a billionaire and I am not, I can't predict his moves, but I know enough not to trust him.
