OpenAI is very unlikely to go bankrupt, but they could be in such a difficult financial position that they would have to make painful compromises with Microsoft and/or Nvidia and lose most of their leverage.
Microsoft, largest software company in the world, has (publicly and privately) admitted that it is in their best interest to ensure that OpenAI remains the leading ai company for at least the next seven years.
As for nvidia, if OpenAI has less leverage, that necessitates a different ai company having more. Who would it be?
