SpaceX bonds sell off days after AI and rocket group’s $25bn debt deal

SpaceX’s new $25 billion bond sale has already moved from a strong launch to a weaker secondary market, with investors demanding higher compensation just days after the debt was priced.

The shift matters because the issue was heavily oversubscribed at launch. Reporting cited order books ranging from about $89 billion to $98 billion, a sign that the company’s first major public bond deal initially drew broad demand.

By June 26, however, the tone had changed. MarketWatch reported that the 5.35% tranche had widened from 106 basis points to 112 basis points above risk-free rates, while longer-dated bonds widened more. The Financial Times said the 10-year yield was nearing 6% and the spread over Treasuries had climbed above 1.6 percentage points.

From oversubscribed deal to weaker trading

Wall Street Journal reporting on June 23 said SpaceX finalized terms on the $25 billion bond sale. The deal was structured in five tranches running from five to 30 years.

The proceeds were described as going toward repaying an earlier bank or bridge loan and funding other corporate spending. That made the new issue an important refinancing step as well as a source of fresh capital.

The speed of the selloff is what caught attention. Within days of pricing, the bonds were trading weaker despite the size of the order book, suggesting investors were recalibrating their view of the credit rather than disputing the company’s access to the market.

What investors are reacting to

The widening matters because it can raise SpaceX’s borrowing costs if the trend continues. It also affects how the market prices the company’s ability to return for more debt in the future.

The reporting points to a broader debate over how to value the company’s credit. SpaceX has been described as investment-grade, but the widening spreads indicate some investors are starting to price the debt closer to speculative levels than to the tighter spreads typically associated with stronger credits.

Investors are also paying close attention to the maturity profile. Reporting said the longer-dated tranches were under particular pressure, which suggests more caution about SpaceX’s long-term debt risk than about the shorter bonds.

Why the market is nervous

The concern is not just about one bond issue. Investors are questioning SpaceX’s ability to service debt over time given its lack of profitability and large future capital needs.

The company is being discussed in the market not only as a space business but also as an AI and infrastructure story, which has intensified scrutiny of future spending plans. Those ambitions may support growth, but they also increase uncertainty about how comfortably the company can fund expansion while servicing a larger debt load.

Moody’s and Fitch were cited in the reporting as part of the broader credit backdrop, though no fresh ratings action was identified in the available coverage.

What happens next

No new company response was cited in the available reporting, and the secondary market is still moving. That leaves open the question of whether the bonds stabilize after the first week of trading or keep drifting wider.

The next signals to watch are whether the spread widening persists, whether rating agencies update or reaffirm their views, and whether SpaceX or its bankers provide more detail on how the company plans to balance expansion, debt service and future funding needs.
