After SpaceX's 16% plunge
Analysis
For an industry built on literal rocket science, Wall Street’s sudden cold feet about SpaceX’s AI borrowing may seem like a distraction. But the $600 billion value waterfall — from an IPO darling to a cautionary tale in just three days — carries deep implications for space contractors, satellite operators, and defense partners who depend on the company’s launch reliability. Can Elon Musk’s conglomerate keep its eye on the cosmos while chasing artificial intelligence billion-dollar deals?
SpaceX shares plunged 16% on Monday, June 22, 2026, to close at $154.60, marking the lowest level since the company’s first trading session just days earlier. The third consecutive daily decline pushed the three-day loss to 23%, erasing more than $600 billion in market value and leaving the company’s market capitalization at just over $2 trillion. The sell-off accelerates a volatile start to public life for the rocket, satellite, and AI conglomerate, which debuted with a record $75 billion initial public offering. The decline was triggered by the company’s announcement that it will issue investment-grade bonds for the first time, part of a broader borrowing strategy to fund aggressive expansion into artificial intelligence. The bond sale is expected to raise at least $20 billion.
The third consecutive daily decline pushed the three-day loss to 23%, erasing more than $600 billion in market value and leaving the company’s market capitalization at just over $2 trillion.
The magnitude of the rout underscores the intense speculative fervor surrounding SpaceX’s IPO. With only 4.2% of total shares outstanding available to trade on day one, the limited float fueled extreme price swings and attracted massive retail interest. Over the first five sessions, retail investors purchased a net $405 million in shares, the strongest retail debut for any IPO in recent history, according to market data. Yet Monday’s sell-off suggests that early momentum may have exhausted the pool of voracious buyers. As Michael O’Rourke, chief market strategist at JonesTrading, put it: “Sellers are back in control. Anyone in the world who wanted to buy this has bought it already.”
The bond offering decision highlights Elon Musk’s dual-track capital strategy: leveraging debt markets to finance capital-intensive AI infrastructure while preserving equity upside. SpaceX’s acquisition of Musk’s xAI in February 2026 positioned the company as an AI powerhouse, integrating large language models with its space and satellite networks. The freshly inked multibillion-dollar computing deal with Reflection AI, an AI startup, underscores the commercial urgency of these AI bets. However, the debt issuance introduces new risks: higher leverage ratios and potential credit rating scrutiny could weigh on the stock, especially if AI revenue fails to materialize quickly.
What to Watch
The sell-off also casts a shadow over the broader IPO pipeline. Industry watchers are closely monitoring SpaceX as a bellwether for the upcoming listings of AI unicorns like Anthropic and OpenAI, both of which are rumored to seek public market valuations near $1 trillion later this year. SpaceX’s post-IPO turbulence may dampen appetite for similarly high-multiple, capital-intensive AI names, even as its own valuation remains about 15% above the $135 IPO price. The initial exuberance, followed by a sharp correction, serves as a cautionary tale for AI startups and their investors weighing the public route.
Looking ahead, the key questions are whether SpaceX’s core space launch and satellite services can provide enough stable cash flow to offset the cash burn from AI expansion, and whether the bond market will welcome the new debt at attractive terms. The next weeks could see further volatility as lock-up expirations approach and institutional investors reassess the company’s risk-reward profile. For now, the stock’s plunge represents a dramatic wake-up call: even the most celebrated IPO of the decade cannot defy gravity when the market turns skeptical about an AI-fueled borrowing binge.

How we covered this story
Every story in our space & defense coverage is assembled from multiple primary sources, cross-referenced for factual consistency, and scored along three independent dimensions: sentiment, operational impact, and source-cluster confidence. Single-source rumors and unverifiable claims do not pass our editorial gate. When a story shows "Verified by N sources" with N≥2, the development is independently corroborated; when N=1, we mark it explicitly so readers can weigh the signal accordingly.
Impact scoring uses a 1-10 scale weighted toward regulatory, financial, and operational consequence rather than coverage volume. A topic that runs in every outlet but moves no real decisions ranks lower than a niche regulatory filing that reshapes how operators in the space & defense space have to behave. Read our full methodology for the scoring rubric, our glossary for term definitions, and our trends index for the longitudinal view across the beat.
Sources are only linked to a story once they clear our classification pipeline at a minimum 35 percent relevance threshold. According to that methodology, reviewed July 2026, this follows multi-source corroboration standards recommended by journalism research bodies such as the Reuters Institute for the Study of Journalism.
