SpaceX’s $25 billion bond deal in late June has proven to be a dud amid apparent investor concern that the company will rely on the debt markets for its massive projected capital spending over the coming years. In a widely hyped sale, SpaceX sold the $25 billion of debt following its IPO in five bond tranches with maturities ranging from five years to 30 years. There were reports that the deal was more than three times oversubscribed and SpaceX was able to price the bonds at narrower yield premiums above U.S. Treasuries than had been expected.
