SpaceX's $25 billion debut bond sale shows you how much credit investors will extend to Elon Musk's company. It also shows the IPO didn't settle the harder question: how much of xAI's cash burn now sits on SpaceX's balance sheet.
The order book was enormous. The Wall Street Journal reported that SpaceX finalized a $25 billion bond sale this week, after demand reached about $89 billion and the company upsized the deal from an earlier $20 billion target. Five tranches of debt, maturing between 2031 and 2056, priced at coupons ranging from 5.35% to 6.65%. Settlement was set for June 26. For bond buyers, that is a rare chance to buy investment-grade paper tied to rockets, Starlink subscriptions, government contracts and Musk's AI ambitions in one trade.
For shareholders, the story is less tidy. SpaceX had only just come public on June 12, selling 555.6 million shares at $135 each and raising $75 billion in the largest IPO on record. The Guardian reported that the offering valued the company at about $1.77 trillion before trading began, then pushed its market value above $2 trillion by the close. The stock did what hot IPOs do: it ran. Then it fell hard once investors had to look past the opening-day spectacle.
You can see the tension in the trading. Business Insider reported that SpaceX closed at $154.60 on June 22 after a three-day slide, down 27% from its June 16 closing high of $211.39. Investopedia later noted that the shares touched their lowest post-IPO levels as the bond plan came into view. The company was still above its $135 IPO price, but that won't comfort anyone who chased SPCX near $200 because they thought they were buying a clean launch-and-satellite growth story.
The debt raise is really an xAI story. SpaceX took on a bridge loan of up to $20 billion earlier this year as part of its merger with Musk's AI startup, and the company said proceeds from the bond sale would repay that bridge loan in full. That removes the September 2027 maturity cliff, which was the obvious near-term risk. It doesn't remove the business underneath it.
xAI is not a small side project anymore. Reuters reported in February that SpaceX's acquisition of xAI carried financial, tax and legal benefits for investors on both sides of the deal. The price was scale. SpaceX is now tied to Grok, X, data center spending and AI infrastructure costs at the same time it is still funding rockets, Starship development and Starlink expansion. That is a lot of ambition to carry, even for a company investors clearly want to believe in.
Frankly, the $89 billion order book is easy to overread. Bond investors are not making the same bet as common shareholders. They are buying a coupon, and they sit ahead of equity holders if things go wrong. A 2056 SpaceX bond at 6.65% can make sense for a fixed-income desk hunting yield even if the stock is too expensive at a $2 trillion-plus valuation. Those are different instruments with different pain thresholds.
There is still a strong case for the lenders. Starlink gives SpaceX a recurring revenue base. Falcon 9 remains central to commercial launch. Government contracts give the company a floor most young public companies never get. Business Insider also reported that SpaceX had $100.8 billion in cash and equivalents as of June 19, so this is not a company scraping for payroll. The better reading is more precise: SpaceX is choosing to term out expensive merger financing while the credit market is open and hungry.
That is sensible. It is also revealing.
The stock market sold the IPO as access to one of the world's most important private companies. The bond market is now showing you the financial machinery behind that access. SpaceX can raise $75 billion in equity and still turn around for $25 billion in debt because Musk's combined empire wants to fund Mars, satellites and AI at once. If you own the stock, you own that whole package now, not just the rocket company people understood five years ago.
The deal helps in the short term. The bridge loan is gone, the maturities are stretched out, and analysts who called the refinancing a technical positive have a point. But SpaceX shareholders are left with the real test: whether xAI can become more than a drain on cash from a stronger parent. The bond sale didn't answer that. It just bought more time for Musk to prove it.
