People here throw around crazy numbers - the dude above was claiming they have some insane good margins, numberd that he took out of his ass.
The only evidence I have is that they are incredibly unprofitable, and they keep raising insane amounts of capital like crazy.
There was a leak sometime ago that they were EBITDA positive during a quarter where they didn't pay for part of their compute. And EBITDA is a cute metric to use when depreciation is actually very important to them, as a model from a year or so ago is nearly worthless.
