SpaceX Stock Plunges 16% on Bond Debut, Exposes Valuation Gap

Published by James Harris on June 23, 2026June 23, 2026

SpaceX’s bond market debut triggered a 16.43% single-day collapse in its share price, erasing $400.8 billion in market value and dragging the stock to its lowest point since IPO day. That is not a routine post-IPO correction. That is the market repricing what it thinks the company is actually worth.

The bond offering itself was not the problem in isolation. SpaceX announced it would issue its first investment-grade bonds to retire a bridge loan of up to $20 billion taken on to fund the xAI merger, and it disclosed $100.8 billion in cash as of mid-June. Those are not the numbers of a distressed company. What spooked investors was the debt headline landing on top of an already stretched valuation: KeyBanc’s Michael Leshock, initiating coverage with no price target, noted the stock was trading near 29 times his 2027 revenue forecast, a steep multiple against peers across space, telecom, and AI. Morningstar had already put fair value at $62 before the bond news broke, with a best-case ceiling of $169. The IPO priced at $135, the stock peaked at $225.64, and it is now trading around $151. The range of analyst targets, from $62 to $401, is not a sign of healthy debate. It is a sign that nobody has a firm grip on the fundamentals yet.

SpaceX went public in the largest offering in history just weeks ago. The market has not had time to form a consensus, and the first major negative catalyst arrived before most institutional buyers had even settled their positions.

The August 11 earnings report now matters more than the bond sale itself. That date unlocks lockup rights for 20 percent of insiders, with another 10 percent freed if the stock holds above the $135 IPO price. Insider selling pressure arriving this early in a stock’s public life, before a stable shareholder base has formed, tends to extend drawdowns rather than resolve them. Potential index fund inclusion this week could absorb some of that supply, but the timing is tight. The broader question Leshock raised, whether Starship can demonstrate reliable performance, is the kind of technical milestone that tends to reset institutional conviction on aerospace names more than any quarterly print.

Wall Street’s average 12-month price target still sits at $187.80, which implies meaningful upside from current levels. But that average is being pulled hard by the $401 outlier, and the distance between the bull and bear cases suggests the stock is going to remain volatile until either the Starship program delivers a clear operational proof point or the xAI integration starts showing up in revenue projections that analysts can actually model.
