The details on the Saudi PIF funding confirm what many on this thread inferred. So in that respect, it's not news.
But it is interesting to note the shifting context. The funding for Musk's Twitter go-private is a list of everybody-but-Goldman. For the Tesla go-private, only a few were smart in looking toward future business. For example, Silver Lake. It appears that Goldman Sachs insists on a poisoned well -- maybe they think that they will always be able to be on the other side of the table to Musk, as with Twitter. Did Musk have a bad experience with Goldman in the Tesla go-private beyond the $200 million that it is demanding of Tesla?
