A very large chunk of GAAP losses are attributable to stock comp expense (a quick and easy way to check cumulative profits/losses is looking at the balance sheet’s equity section for “accumulated deficit”) which still gets counted as an expense but since it’s non-cash it’s not a drain on whatever the company has raised. If you look at Uber’s last three FY’s, they’ve cumulatively reported losses of about $16 billion, and stock comp has been about $6.5 billion of that. For the vast majority of public companies this isn’t as material but for all these VC-backed, Bay Area-type tech companies they have this systemically dysfunctional culture where they dole out stock and options to no end.
