SPCX Round-Trips Its IPO Pop as SpaceX Launches a $20B Bond

The Bond That Moved the Tape

SpaceX formally launched its first investment-grade bond sale, targeting at least $20 billion across notes maturing in five to 30 years. That came barely ten days after the company closed the largest IPO in history, raising roughly $75 billion at $135 a share and debuting near $161. Bloomberg first reported bankers were preparing the deal on June 18; today's SEC filing and investor calls turned the rumor into reality, and SPCX fell for a third straight session, down 10.29% over the last 23 hours to $162.90.

The proceeds aren't earmarked for growth. SpaceX said it will repay the bridge loan that financed February's xAI merger in full — the facility that makes up the bulk of its roughly $29.1 billion in long-term debt and matures in September 2027. Issuing $20 billion of debt to refinance debt, weeks after raising $75 billion in equity, is exactly the kind of sequence that makes a freshly public stock read less like a winner and more like a capital sink.

The Cash Paradox

The number that makes this selloff legible: SpaceX disclosed about $100.8 billion in cash as of June 19. A company with $100 billion in the bank borrowing another $20 billion isn't doing it because it's short on money today — it's doing it because of where the spending curve is pointed. Analysts have started attaching numbers to that curve: Goldman Sachs and Evercore ISI see capex topping $1 trillion by 2031, and Oppenheimer models net debt reaching roughly $400 billion by then — a balance sheet that would outweigh any U.S. public company.

The intensity isn't abstract. SpaceX is funding Starlink's buildout, Starship development, and the AI ambitions it absorbed with the $60 billion all-stock acquisition of coding startup Cursor, plus roughly $75 billion in data-center commitments tied to Google and Anthropic. The bond itself is investment-grade — Baa1 from Moody's, BBB+ from Fitch, BBB from S&P — so this isn't a credit scare. It's the market repricing a stock that ran to a $1.7 trillion-plus valuation on launch-cadence optimism and is now being asked to underwrite a decade of spending.

The Setup

Two things make this leg down different from the first post-IPO wobble. First, listed options only began trading June 17, so this is the first decline where shorts and hedgers can actually press the stock rather than just dump shares into a thin float. Second, that float cuts both ways: only a small slice of SpaceX trades freely, and a chunk of locked shares is set to unwind around the first earnings report in July or August, layering real supply onto a name that has already lost its bid.

At $162.90, SPCX has round-tripped essentially its entire post-IPO pop — back near its ~$161 first-day close and about 28% below the $225.64 peak set on June 16. The bond removes the last "they're flush, they don't need money" line from the bull case. Until the deal prices and the early lock-ups clear, the path of least resistance has flipped.
