• SpaceX shares fell 3.9% on Thursday, slipping below their opening price on the first day of trading.
  • The decline marks a cooling of the post-IPO rally, as investors reassess valuation amid broader tech volatility.
  • Analysts point to thin float and market chatter about a potential bond issuance as contributing factors.

Post-IPO Honeymoon Fades

SpaceX’s stock lost 3.9% in Thursday’s session, closing below the $79 open price from its trading debut last month. The pullback ends a stretch of outsized gains that had lifted the shares more than 40% since the IPO, according to data compiled by Bloomberg.

“The initial euphoria is giving way to a more measured assessment of SpaceX’s fundamentals,” said a portfolio manager at a large-cap fund who asked not to be named because they are not authorized to speak publicly. “People are starting to ask harder questions about cash burn and Starlink’s unit economics.”

Thin Float Amplifies Swings

The stock’s volatility is typical of high-growth, high-profile IPOs, especially those with a limited number of shares available for trading. SpaceX’s public float is estimated at roughly 10% of total shares outstanding, making it susceptible to sharp moves on moderate volume.

The slide also comes amid broader weakness in tech and space-related equities, as rising interest rates weigh on long-duration assets. The ARK Space Exploration & Innovation ETF, a bench mark for the sector, fell 2.1% on the same day.

Bond Chatter Adds Pressure

Market participants have speculated that SpaceX may soon tap the corporate bond market to finance its ambitious Starship development and Starlink expansion. Such an offering could dilute existing equity holders or signal that the company’s capital needs are greater than initially expected.

A spokesperson for SpaceX declined to comment on the stock’s move or any potential debt financing.

Looking Ahead

Traders will be watching for any announcements regarding launch cadences, Starlink subscriber growth, or regulatory developments that could affect SpaceX’s trajectory. Quarterly earnings, due in about six weeks, will provide the clearest picture of the company’s financial health since going public.
