Edit: Based on the info I was able to find, it looks like this is indeed false information and not true at all.
I can find no evidence that SpaceX is having trouble raising money or that their recent raises have gone poorly. No evidence. But I can find a lot of people explaining why these numbers are incorrect and why it is false to say that SpaceX is having trouble raising money. A lot. Here are a few.
