SpaceX stock tumbles 16.4%, shaving off most IPO gains since debut

SpaceX stock tumbles 16.4%, shaving off most IPO gains since debut

SpaceX (SPCX) stock tumbled again on Monday, giving it three straight down days after a massive run-up following its IPO earlier this month. SpaceX also confirmed its first-ever bond issuance in a filing.

SpaceX Shares Suffer Biggest Post-IPO Drop

SpaceX (NASDAQ: SPCX) continued its sharp decline on Monday, marking its third consecutive losing session after a remarkable rally following its highly anticipated initial public offering (IPO) earlier this month.

The stock closed at $154.60, down 16.4% for the day — its largest single-day decline since debuting on public markets. The sell-off followed a 5% drop on Wednesday and a 3.6% decline on Thursday. U.S. markets were closed Friday in observance of the Juneteenth holiday.

Despite the recent pullback, SpaceX shares remain approximately 14% above their IPO price of $135 per share. The stock opened at $150 on its first trading day on June 12 and quickly surged to nearly $225 per share at its peak.

At the height of the rally, SpaceX briefly surpassed both Amazon and Microsoft in market capitalization, becoming the world's fourth-most valuable publicly traded company.

Stock Performance

  • Closing Price (June 22): $154.60
  • Daily Change: -$30.40 (-16.43%)
  • After-Hours Trading: $156.77 (+1.40%)

 

SpaceX Confirms First-Ever Bond Offering

Adding to investor concerns, SpaceX officially confirmed plans for its first-ever bond issuance in a regulatory filing released Monday morning.

While the company did not disclose the total size of the offering, it stated that proceeds from the notes sale would primarily be used to repay outstanding borrowings under its existing bridge loan facility, along with related fees and expenses.

According to reports from Bloomberg, the bond offering could be valued at approximately $20 billion.

The bridge loan was arranged earlier this year following SpaceX's acquisition of Elon Musk's artificial intelligence startup, xAI, in February.

Several major Wall Street banks reportedly participated in the bridge financing and are expected to lead the bond sale, including:

  • Bank of America
  • Citigroup
  • JPMorgan Chase
  • Goldman Sachs
  • Morgan Stanley

 

Why the Bond Sale Could Pressure Shares

Debt offerings can sometimes create headwinds for a company's stock price, particularly when investors worry about:

  • Rising interest expenses
  • Increased leverage
  • Future financing needs
  • Potential pressure on profitability

Although many investors anticipated SpaceX's move to refinance its bridge loan, the confirmation of a large debt issuance may have contributed to the latest wave of selling.

 

Another Concern: Insider Share Unlocks

Beyond the bond offering, investors are also closely monitoring upcoming lock-up expirations that could significantly increase the number of shares available for trading.

According to 22V Research strategist Jeff Jacobson, SpaceX insiders may gain the ability to sell substantial portions of their holdings over the coming months.

Key unlock events include:

August Earnings Unlock

  • Approximately 20% of insider shares become eligible for sale following SpaceX's earnings report, expected in early to mid-August.

Performance-Based Unlock

  • An additional 10% of shares may be unlocked if the stock trades at least 30% above its IPO price.

Scheduled Unlocks

  • Roughly 7% of shares are scheduled to unlock around August 21.
  • Another 7% unlock is expected around September 10.

Jacobson estimates that insiders could potentially sell up to 44% of outstanding SpaceX shares by early September.

 

What It Means for Investors

The combination of a large debt offering and significant upcoming share unlocks is creating uncertainty around SpaceX's near-term outlook.

One major factor is the company's extremely limited public float. Following the IPO, only about 4.2% of SpaceX shares were available for public trading. If insiders begin selling after lock-up restrictions expire, the tradable share count could increase by as much as 900%, dramatically altering supply-and-demand dynamics.

While SpaceX remains one of the market's most closely watched growth stories, investors are now shifting their focus from IPO excitement toward the practical realities of financing, insider selling, and long-term valuation.

Take away

After an explosive post-IPO rally, SpaceX stock is facing its first meaningful test. Monday's 16% plunge, confirmation of a major bond offering, and the prospect of substantial insider share sales have prompted investors to reassess the company's near-term trajectory.

The coming months — particularly the August earnings report and subsequent lock-up expirations — may prove crucial in determining whether SpaceX can regain momentum or faces additional pressure as more shares enter the market.
