Just 30 days after the most anticipated IPO in market history, SpaceX stock has fallen below its $135 initial public offering price, marking a stunning reversal for a company that briefly turned Elon Musk into the world's first trillionaire. On Wednesday, SPCX shares dipped as low as $134.82 in intraday trading before closing at $135.27, capping a four-day losing streak that has erased over $400 billion in market value since the stock peaked at $207 in its first week of trading.
The fall from grace has been almost as dizzying as the rise. SpaceX raised $86 billion in its June IPO, the largest in history, with underwriters exercising options to sell additional shares on top of the $75 billion initially raised. At its peak, the company commanded a $2.2 trillion market capitalization. Today, that figure sits closer to $1.8 trillion, and analysts warn the floor may be far from found.
The stock was added to the Nasdaq-100 on July 7 under a rare rule change that allowed newly public companies to join the index just 15 days after listing, a signal of just how much institutional enthusiasm surrounded the offering. But that enthusiasm has curdled quickly as investors begin scrutinizing the company's massive spending commitments and debt load in an environment where hype alone no longer justifies a $2 trillion valuation.
What Happened: The Mechanics of the Selloff
The immediate trigger appears to be a combination of profit-taking and rebalancing. Early retail and institutional buyers who got in at or near the $135 IPO price and watched the stock surge more than 50% in days are now locking in gains ahead of a looming unlock event. At least 20% of SpaceX shares held by current and former employees are scheduled for release after the company discloses its second-quarter earnings, and the overhang of insider selling is spooking the market.
SpaceX employee stock plans have been a source of tension internally for years. Many early employees hold options and shares valued at fractions of the current price, and the lock-up expiration represents the first real opportunity for rank-and-file staff to cash out after years of private-market illiquidity. Analysts at Goldman Sachs and Morgan Stanley have both flagged the lock-up as the single largest near-term risk to the stock, with one estimating that insider selling could put downward pressure on shares for weeks after the earnings release.
The broader market environment has not helped. Rising interest rates and a rotation out of high-growth, high-valuation names have hit every stock that trades on narrative rather than earnings. SpaceX has yet to report a full quarter as a public company, and with no dividend and an uncertain earnings trajectory, the stock is priced entirely on forward expectations -- expectations that are now being recalibrated downward.
The Trillionaire Math: Musk's Net Worth Takes a Hit
Elon Musk's personal fortune has been the most visible casualty of the selloff. At the IPO peak, Musk's stake in SpaceX alone was valued at roughly $700 billion, pushing his total net worth past $1 trillion when combined with his holdings in Tesla, xAI (now merged into SpaceX), and other companies. Today, his net worth has retreated to approximately $800 billion, according to Bloomberg's Billionaires Index, placing him back near the same territory he occupied in mid-2025.
While $800 billion is still an almost incomprehensible sum, the speed of the decline is what matters to investors and to Musk himself. The billionaire has been unusually quiet on social media during the selloff, a stark contrast to his combative style during past Tesla stock declines. Some market watchers interpret the silence as a signal that even Musk recognizes the valuation was stretched.
The wealth evaporation has broader implications. SpaceX's post-IPO war chest was critical to funding the company's aggressive expansion into AI infrastructure. Since going public, SpaceX has announced the $60 billion acquisition of AI coding startup Cursor, merged xAI into the corporate structure, and begun leasing computing power to rivals Anthropic and Google at two newly constructed terrestrial data centers. These bets are long-term plays that require sustained capital -- capital that becomes more expensive to raise when the stock price is declining.
AI Ambitions Meet Wall Street Realities
SpaceX's IPO pitch was remarkably successful because it told a story that extended far beyond rockets. The company positioned itself not as a launch services provider but as an AI infrastructure juggernaut with a unique moat: the ability to deploy orbital data centers powered by solar energy that could process AI workloads at the edge of space. The vision captured the imagination of institutional investors who saw parallels to the early days of cloud computing.
But building orbital data centers costs billions, and the timeline to revenue is measured in years, not quarters. The Cursor acquisition adds another $60 billion in integration risk. Meanwhile, SpaceX faces growing competition on multiple fronts: Blue Origin's New Glenn rocket is approaching operational readiness, China's Long March family continues to improve, and terrestrial AI data center operators like CoreWeave and Oracle are expanding capacity faster than any space-based alternative could match.
The market is essentially asking a question that no one wanted to ask during the IPO euphoria: what is SpaceX actually worth today, not in 2035? The answer, based on the current stock price, appears to be significantly less than $2 trillion. Whether the stock finds a floor near its IPO price or continues to decline depends on the company's ability to deliver quarterly earnings that justify the narrative. The next earnings report will be the first real test, and the lock-up expiration that follows will separate true believers from those who were simply riding the wave.
