SpaceX plunges 31.5% from peak, erasing $600B: What it means for mega-IPOs

SpaceX’s historic public listing has become a cautionary tale of euphoria and crash, as the company’s market value swung by nearly a trillion dollars within two weeks of its Nasdaq debut. On June 12, 2026, SpaceX raised $75 billion at $135 per share in the largest IPO ever, with total proceeds reaching $85.7 billion after underwriters exercised the greenshoe on June 15. By June 16, shares had leaped 67% to an intraday high of $225.64, briefly making SpaceX one of the top five U.S. companies by market capitalization, surpassing both Amazon and Microsoft. Just days later, the stock had cratered to $154.60 at the close on June 22—a 31.5% drop from the peak, erasing roughly $600 billion from the closing peak valuation and $920 billion from intraday highs. The immediate spark for the final session’s 16.4% single-day plunge was an SEC filing confirming SpaceX’s first investment-grade bond sale of at least $20 billion. This move, reported by Bloomberg on June 18, rattled investors who had just absorbed the largest equity raise in corporate history, suggesting the $85.7 billion haul might still be insufficient. Bond documents disclosed cash reserves of approximately $100.8 billion, but also revealed the scale of capital appetite. Steve Westly, a veteran venture capitalist and former Tesla board member, crystallized the core tension by describing SpaceX as three moonshots bundled together—Starship, Starlink, and perhaps deep-space exploration—requiring at least two to succeed in order to justify a $2 trillion valuation. The quick reversal underscores the fragility of post-IPO momentum when the underlying business is capital intensive and the path to profitability remains distant. For public markets, the episode introduces a new level of volatility in an era where private companies can stay on private markets until they are of gargantuan size. It also tests the premise that retail and institutional investors will maintain faith in multi-decade, speculative engineering bets that demand continuous funding on a scale never before attempted by a publicly traded entity. The long-term implications are profound: if SpaceX’s bond sale succeeds, it will set a precedent for other mega-cap growth companies to complement equity with debt, potentially altering capital structures across the technology sector. However, if the offering falters or the stock continues to lose ground, SpaceX may find itself forced to scale back its most ambitious projects—essentially deciding which moon shot to abandon. For now, the $600 billion wipeout stands as the largest nominal value destruction in such a short period, raising urgent questions about market liquidity, price discovery, and whether the IPO was priced to perfection for a reality that was always far more uncertain.
