SpaceX, Elon Musk's rocket company, has secured a Baa1 investment-grade rating from Moody's Ratings, a move that has drawn skepticism from credit markets due to the company's limited public financial record, sustained negative free cash flow, and years of heavy capital spending ahead. The rating, announced last week, places SpaceX on par with Nvidia Corp.'s initial Baa1 rating almost a decade ago, when Nvidia had over US$1 billion in free cash flow and a light debt load after 16 years as a public company.
Unprecedented Bond Offering
SpaceX is seeking to raise between US$20 billion and US$25 billion from a debut bond offering on Tuesday, after attracting about US$30 billion of investor orders even before the sales process formally began, according to people with knowledge of the matter. At that size, the deal would rank among the biggest of the year, based on Bloomberg-compiled data. This level of demand is rare in investment-grade credit, a market built around steady cash flows, manageable leverage, and dependable returns.
“This should be a phenomenal opportunity on the equity side over the next 10 or 20 years,” said Sal Naro, chief investment officer of Coherence Credit Strategies. “On the fixed-income side, it appears that the agencies are giving them a lot of leeway and a lot of positivity for events that are going to happen in the near- or middle-term.”
Strengths and Risks
For Moody's, S&P Global Ratings, and Fitch Ratings, the investment-grade case hinges on SpaceX's unique assets: a dominant launch provider central to the U.S. space program, a Starlink satellite network generating billions in recurring revenue, and sufficient liquidity to fund its AI expansion. However, SpaceX lacks typical hallmarks of a high-grade borrower. It is spending heavily, burning through cash, and relying on future growth to make the numbers work.
S&P, which grades SpaceX one notch lower than Moody's at BBB, expects the company to remain cash-flow negative until 2030, with the burn rate rising sharply next year and again in 2028. To finance that gap, SpaceX is expected to lean much more heavily on debt, with borrowings climbing to US$132 billion in 2028, up from close to zero now after adjusting for cash and lease liabilities, according to S&P.
Complex Rating Debate
Balancing these risks against SpaceX's market position made for an unusually complicated rating debate. Naveen Sarma, S&P's primary analyst for SpaceX, said on a webinar that it was “one of the more interesting committees I’ve had in my 20 years at S&P.” The rating reflects a bet on Musk's ambitions: reusable rockets, a globe-spanning satellite network, artificial intelligence, and even data centres in space.
In equities, such leaps are routine, with buyers paying for big stories in hopes of explosive gains. Yet in investment-grade credit, it is far rarer. The skepticism underscores the tension between SpaceX's extraordinary potential and the financial discipline typically required for a high-grade rating.
