SpaceX has a new valuation, according to Bloomberg. It’s an eye-popping $400 billion, up from a recent $350 billion, following a capital raise and stock sales by insiders. The $50 billion increase makes Musk about $20 billion richer, as he is thought to hold some 40% of SpaceX stock.

"I think it'll help us," Trump said about Elon Musk's "America Party." He added that "third parties have always been good for me."

That would mark the largest-ever valuation for a privately held US company, surpassing SpaceX’s previous record of US$350 billion.
