SpaceX didn’t even wait two weeks. The company completed one of the largest IPOs in history on June 12, 2026, and by June 22 it was already announcing its first-ever bond offering, targeting roughly $20 billion in senior unsecured notes. For a company that just raised up to $86 billion through its public listing, the speed of the pivot to debt markets is striking.
The stock didn’t love it. Shares dropped approximately 13% to 16% on the day the bond sale was announced, a bruising reaction for a company that had just debuted on the Nasdaq at around $135 per share.
What the bond money is actually for
The company reported post-IPO cash reserves of approximately $100.8 billion. The primary purpose of the $20 billion bond offering is to refinance a bridge loan that SpaceX took out in March 2026. That loan was part of the merger with xAI, Elon Musk’s artificial intelligence venture. The remaining proceeds will fund general corporate purposes, including AI investments and next-generation rocket development.
SpaceX secured investment-grade credit ratings from all three major agencies roughly a week before the bond announcement. Moody’s assigned Baa1, Fitch gave BBB+, and S&P rated it BBB. Those ratings mean pension funds and insurance companies can buy the bonds, which expands the pool of potential buyers and keeps borrowing costs down.
