SpaceX shares fall below IPO price as short interest rises

The BareStory

SpaceX shares traded below their $135 initial public offering price this week for the first time since the company went public last month, according to the provided market summaries. The decline came ahead of the company’s 13th Starship test flight, scheduled for Thursday.

Short interest in the company has increased sharply, according to S3 Partners. The firm said about 185 million SpaceX shares were sold short, equal to roughly 29% of the publicly tradable float and about $25 billion in bearish positions, up from an estimated 40 million shares three weeks earlier.

S3 Partners said demand for short positions has continued since the IPO. Separately, KeyBanc Capital Markets said SpaceX’s initial public float represented about 5% of its roughly 13 billion shares outstanding, with most shares still subject to lockup restrictions.

KeyBanc estimated that the first major lockup expiration could occur around the company’s second-quarter earnings report, potentially making about 11% of outstanding shares eligible for sale. It also said Elon Musk’s stake, described as about 42% of outstanding shares, is locked until June 2027.

Left Perspective

• Expose Fragile Hype Value: investor protection and skepticism toward speculative wealth narratives. SpaceX trading below its $135 IPO price so soon after going public reads as a warning that public buyers may have absorbed a valuation built more on enthusiasm than proven market confidence. The timing ahead of the 13th Starship test flight reinforces the view that ordinary investors are being asked to carry high technical and financial uncertainty. The decline is treated as a failure of pricing discipline around a high-profile company.

• Flag Insider Advantage Value: fairness in market access and concern over asymmetric power. KeyBanc’s estimate that only about 5% of roughly 13 billion shares entered the public float suggests a tightly controlled market where insiders retain enormous influence while public investors face volatility. Lockup restrictions may protect insiders from immediate losses while outside buyers experience the first wave of price discovery. The potential release of about 11% of outstanding shares around the second-quarter earnings report is seen as a future supply shock that public investors must anticipate before insiders fully face market judgment.

• Warn Against Extraction Value: protection against institutional extraction and unequal risk transfer. The jump to about 185 million shares sold short, equal to roughly 29% of the publicly tradable float and about $25 billion in bearish positions, signals that sophisticated traders see vulnerability in the offering structure. Rising demand for short positions since the IPO is read as evidence that the market may be correcting an overpromoted asset. The long-term fear is that IPO excitement privatizes gains for early holders while socializing losses among late public buyers.

Right Perspective

• Defend Price Discovery Value: market efficiency and the belief that prices should adjust quickly to new risk information. SpaceX falling below its $135 IPO price is not automatically a scandal; it is the market testing whether the initial valuation matches current expectations. The scheduled 13th Starship test flight adds a concrete uncertainty that investors are rationally pricing. The decline is viewed as a necessary correction mechanism, not proof of systemic failure.

• Validate Short Discipline Value: liquidity, skepticism, and the stabilizing role of dissenting capital. The rise to about 185 million shares sold short, roughly 29% of the publicly tradable float, shows that bearish investors are willing to put capital at risk rather than merely criticize from the sidelines. A $25 billion short position can be interpreted as disciplined scrutiny of assumptions embedded in a newly public company. High short interest may increase volatility, but it also forces management and bullish investors to confront hard valuation questions.

• Manage Supply Overhang Value: orderly capital formation and institutional continuity. KeyBanc’s estimate that only about 5% of shares are publicly tradable explains why price moves may be exaggerated by a limited float rather than by a collapse in the company’s fundamentals. The possible release of about 11% of outstanding shares around second-quarter earnings is a known event that markets can prepare for and price in. Elon Musk’s roughly 42% stake being locked until June 2027 is seen as a stabilizing commitment that keeps leadership economically tied to long-term performance.

How it may affect me

As a U.S. reader:

• If you bought SpaceX shares at the $135 IPO price, your investment may currently be below its purchase value.

• In the short term, the scheduled Starship test flight and high short interest could contribute to larger price swings.

• Because only about 5% of shares are publicly tradable, everyday investors may see sharper moves than they would in a stock with a larger float.

• Around the second-quarter earnings report, more shares may become eligible for sale, which could affect the stock price if holders sell.

• Elon Musk’s large stake is locked until June 2027, limiting one major source of potential share sales in the near term.
