it is a large spinning plate that can only keep spinning with more money, so the plate gets bigger and bigger, with everyone betting that it would carry on spinnning by itself to the stage that it has become too big to fail, due to the fallout, the impact on the stock market upon others companies would wipe out more than the sum of their debts. It's kinda at that stage now as when one domino falls, the impact on others will follow.

Just a case of too many companies have skin in OpenAI's game for it to be allowed to fail now.
