...that's not how bankruptcy happens. What is this guy's background?
Assets on a balance sheet are held at book value. You can absolutely run GAAP losses that exceed net assets without running into bankruptcy, particularly if you're granting (and having employees exercise) options.
The critical measures are cash in and out and debt-like obligations. None of those metrics point to OpenAI going bankrupt this year unless they do something really fucking creative. (Which, to be clear, is Altman's M.O.)
