SpaceX’s initial public offering may be the largest IPO ever, but it might just be a prelude to the largest merger ever—a combination of Tesla with Elon Musk’s space venture. On April 1, SpaceX reportedly filed confidentially for an IPO. It’s likely to raise $75 billion, more than double the $29 billion Saudi Aramco raised in 2019, and three times the $25 billion Alibaba Group Holding raised in 2014.
