REAL MONEY: Elon Musk’s SpaceX is now valued at $175 billion in the private market—that’s larger than any IPO valuation in history. “Musk is in talks to sell between $500 million and $750 million of SpaceX stock at a valuation of $175 billion or more, Bloomberg reported Wednesday, citing unnamed sources. The figures mean the private space giant, which still hasn’t announced plans to go public, is more highly valued than any initial public offering in U.S. history, topping Alibaba’s $169 billion IPO valuation from 2014.”
