SpaceX generates $89 billion in interest for its inaugural bond sale, marking one of the largest offerings in the US this year.

      TL;DR SpaceX attracted $89 billion in demand for its first bond sale, aiming to raise $20 to $25 billion through five tranches to refinance bridge loan debt.

      According to Bloomberg, SpaceX garnered approximately $89 billion in investor interest for its inaugural U.S. bond sale, paving the way for one of this year's largest investment-grade offerings. The company is looking to collect between $20 billion and $25 billion from a five-part deal anticipated to price on Tuesday. At the lower end of that range, demand would surpass the offering by over four times.

      Price indications for the longest-dated tranche, maturing in 2056, have tightened by about 0.25 percentage points, now sitting at 1.75 percentage points above Treasury yields. The five banks facilitating the sale—Goldman Sachs, Morgan Stanley, JPMorgan Chase, Bank of America, and Citigroup—either declined to comment or did not respond to inquiries.

      The proceeds will be used to refinance a $20 billion bridge loan that SpaceX secured earlier this year to pay off approximately $17.5 billion of high-interest junk debt associated with X and xAI. This bridge loan, arranged by the same five banks, carried an effective rate of around 4.5%, roughly half the cost of the junk bonds it is set to replace. The bond sale will transition this temporary financing into permanent capital market debt.

      This offering follows closely on the heels of SpaceX's record-breaking initial public offering, which raised $75 billion by selling shares at $135 each, resulting in a valuation of around $1.75 trillion. Shares initially jumped to $225 before experiencing a steep decline, losing over 30% from their peak as investors processed the company’s expenditure plans and cash burn.

      The three main credit rating agencies assigned investment-grade ratings to SpaceX on June 18, shortly after the IPO. Moody’s rated it Baa1, Fitch assigned a BBB-plus rating, and S&P rated it BBB, all with stable outlooks. These agencies highlighted SpaceX's strong position in orbital launches and Starlink’s 12 million subscribers as advantages, while noting execution risks associated with the company's AI growth and governance issues stemming from Musk's concentrated control.

      As of June 19, SpaceX reported approximately $101 billion in cash and $29 billion in long-term debt. However, these figures conceal substantial cash outflow. The company posted a net loss of nearly $5 billion in 2025 and incurred an additional $4 billion loss in Q1 of 2026, with negative free cash flow of $14 billion last year, more than double the amount from the previous year.

      Starlink generated $4 billion in operating profit in 2025, but this is being consumed by the AI division. SpaceX acquired xAI in February 2026 as part of Musk's consolidation of his companies and completed a $60 billion all-stock deal to purchase the AI coding startup Anysphere shortly after the IPO. The bond sale is integral to the financing strategy needed to support these acquisitions while ensuring funding for its core rocket and satellite operations.

      Bloomberg Intelligence analyst Robert Schiffman pointed out that the transaction presents investors with an opportunity to purchase debt from a first-time issuer while diversifying their investments linked to the AI trend. Debt investors typically exhibit more caution than equity buyers, and the fourfold oversubscription indicates that even risk-averse capital views SpaceX's revenue streams, particularly from Starlink, as robust enough to service the debt.

      The demand reflects the IPO itself, where individual investors placed orders exceeding $10 billion. Over just two weeks, SpaceX has tapped both equity and debt markets, potentially raising a combined total of $100 billion—an unprecedented amount for any company in public markets within such a short period.

      The key issue for bondholders is whether SpaceX can generate sufficient cash to manage the debt while simultaneously financing Starship development, Starlink expansion, AI infrastructure, and the integration of multiple acquisitions. The company has a revenue foundation, with $19 billion anticipated in 2025, but is currently spending significantly more than its earnings. The bond market's initial response indicates a willingness to take that risk.
