SpaceX's stock has collapsed from a post-IPO peak of $226 to $154.63, erasing $600 billion in market value and forcing the company to tap the bond market for the first time. The dramatic reversal has left investors questioning whether the company's initial valuation was built on hype rather than fundamentals, and raised concerns about how aggressively SpaceX plans to spend on artificial intelligence and data center expansion.

What Happened to SpaceX's Stock After Its IPO?

When SpaceX began public trading on June 12, shares opened at around $150, set by underwriters after building the order book. Within four days, the stock had soared to nearly $226, a gain of roughly two-thirds, making SpaceX briefly more valuable than Amazon and Microsoft. But the rally proved fragile. By Monday, June 23, shares had plummeted to $154.63, down 16 percent in a single day and now trading only 3 percent above the opening price.

The collapse wiped out most of the spectacular gains made after the company's market debut. SpaceX's valuation now sits just above $2 trillion, placing it seventh among the world's most valuable companies, below Taiwan Semiconductor Manufacturing Company (TSMC). The slide erased more than $600 billion in market value over three trading days.

Why Is SpaceX Suddenly Borrowing Money Despite Raising Billions in Its IPO?

On the same day its stock hit bottom, SpaceX announced its first-ever corporate bond sale, targeting around $20 billion in senior unsecured notes. The timing raised eyebrows among investors who saw the rapid fundraising as a red flag. The company disclosed a cash position of roughly $100.8 billion as of June 19, much of it raised in the IPO, alongside $29.1 billion in long-term debt.

The proceeds from the bond sale are earmarked chiefly to repay a bridge loan taken during SpaceX's merger with Elon Musk's artificial intelligence venture xAI earlier this year, with the remainder going to general corporate purposes. That mix of vast cash reserves and fresh borrowing so soon after a record flotation has unsettled some investors, who see the rapid fundraising as a sign of heavy spending ahead as SpaceX scales its AI and data center plans.

How to Understand SpaceX's Financial Strategy

• Bond Market Access: SpaceX received investment-grade credit ratings from all three major agencies (Moody's at Baa1, Fitch at BBB+, and S&P Global at BBB), which open the door to cheaper borrowing and a wider pool of institutional lenders compared to higher-risk debt.
• Debt vs. Equity Dilution: By opting for debt rather than issuing new shares, SpaceX spares existing shareholders further dilution, preserving their economic stake while the company funds its expansion into AI and data centers.
• Cash Burn Concerns: The rapid fundraising suggests SpaceX expects significant spending ahead, which some investors interpret as a warning that the company's ambitious growth plans will require substantial capital deployment in the near term.

The debut bond sale follows the investment-grade credit ratings awarded last Friday by all three major agencies, which represent a milestone for the newly public company. These ratings signal that lenders view SpaceX as a lower-risk borrower, making corporate debt a more attractive financing option than equity dilution.

Investors have grown concerned about the company's spending trajectory. The initial IPO rally rested on a thin pool of freely traded shares and lofty expectations for SpaceX's AI ambitions, leaving it exposed to a sharp reversal once sentiment turned negative. The stock's collapse suggests that the market may have overestimated near-term profitability or underestimated the capital intensity of SpaceX's expansion plans.

The company's decision to borrow $20 billion while holding over $100 billion in cash raises questions about capital allocation. Some analysts view it as prudent financial management, avoiding shareholder dilution during a period of heavy investment. Others see it as a sign that SpaceX's leadership expects spending to accelerate significantly, making debt financing more attractive than equity issuance at current valuations.
