NEW YORK — The biggest initial public offering in stock market history is having the worst first week any investor could have feared. SpaceX shares fell 16.4% on Tuesday, the third consecutive session of heavy losses, and the company’s stock has now given back most of the gains from its first day of trading, according to Yahoo Finance data.
The decline follows a $50 billion drop in market value on Monday, and traders said the selling has been relentless since the IPO price was set. Investor’s Business Daily, which has tracked the stock’s path, described SpaceX as one of the most fragile names in the technology selloff: a combination of high valuation, intense attention and a small free float has made its price swings far larger than those of most listed companies.
The structure of the offering explains part of the volatility. SpaceX sold only a small fraction of its shares to the public, leaving a thin float that amplifies every trade, and the demand that drove the opening-day surge was partly speculative, driven by retail investors who could not buy the stock in private markets. When the technology selloff began, those investors headed for the exits at the same time, and with so few shares available to absorb the selling, the price fell faster than it would have in a more liquid stock.
The company’s fundamentals were not the driver of the decline, analysts said. SpaceX remains the dominant force in commercial launch, with a satellite network that generates recurring revenue and a customer list that includes governments and corporations around the world. The valuation at the IPO, however, assumed growth that the stock market was no longer willing to price in after two days of panic selling in technology shares.
The timing could not have been worse. SpaceX’s listing arrived at the peak of the AI-driven technology rally, and its first week has coincided with the sharpest selloff of the year. The KOSPI’s double circuit breakers, Nvidia’s plunge and the broader rotation out of high-multiple stocks all landed on a stock that had no trading history to anchor investor expectations.
For the company’s early investors and employees, the decline is a paper loss rather than a cash one, since most shares remain locked up under IPO restrictions. The lock-up period, typically six months, will determine whether the selling pressure continues when insiders become free to sell. Analysts said the stock’s path over the coming months will depend as much on the lock-up calendar as on the company’s launch schedule.
The comparison to other megacap IPOs is instructive. Large offerings have historically been volatile in their first weeks, with shares swinging sharply as the market discovers a price for a company that had no public trading history. Some, like the early internet listings of the 1990s, went on to far higher prices after the initial turbulence; others never recovered. The difference, analysts said, is usually the business, and SpaceX’s launch revenue and Starlink subscriber growth are the metrics that will matter.
The selloff has also tested the narrative that a successful IPO validates a company’s long-term prospects. The fact that SpaceX raised billions at a high valuation is not in dispute; the question is whether the public market’s initial enthusiasm will hold. Tuesday’s close suggested that investors who bought at the opening are underwater, and that the stock will need a catalyst — a successful launch, a new contract, or a market recovery — to regain its footing.
Founder Elon Musk has said little publicly about the stock’s decline, and the company has not commented on the trading. The silence is consistent with SpaceX’s posture toward the public market since the listing, and analysts said the company is likely to focus on its operational calendar rather than its share price. The next launch window, the next Starship test and the next Starlink earnings report will arrive regardless of what the tape says.
The valuation debate has sharpened since the listing. Private market investors valued SpaceX at hundreds of billions of dollars before the IPO, and the offering priced at a level that assumed continued growth, but the public market has been less generous. Analysts have noted that SpaceX’s revenue, while growing, remains concentrated: a small number of customers account for a large share of launch revenue, and Starlink’s subscriber growth has begun to slow. The stock’s decline has brought those questions to the surface, and the company’s next disclosures, due with its first quarterly report as a public company, will give investors their first look at the financials behind the hype.
The company’s operational record provides the counterweight. SpaceX launches more rockets than any other provider, its Starship program has made steady progress through test flights, and its Starlink constellation has become a revenue business with millions of subscribers. The company’s history of hitting difficult engineering targets — the landings, the reused boosters, the mega-constellation — has made believers of investors who watched the private market value it at ever higher prices. The public market, which is less patient and more prone to panic, is now applying its own discount to that record, and the gap between the private market’s enthusiasm and the public market’s skepticism will be resolved by the numbers, not by the narrative.
The broader lesson of the week is that the public market punishes uncertainty. SpaceX entered the stock market at a moment of maximum optimism about technology, and it has spent its first week discovering what happens when that optimism recedes. The company’s long-term story — the largest launch provider in the world, with a satellite business that is approaching profitability — is unchanged. Whether the stock price will wait for that story to catch up is the question the next several months will answer.
