The launch went almost perfectly. Starship’s thirteenth test flight executed its profile with what observers called a near-flawless performance — booster recovery, stage separation, all the drama that usually moves a stock. Shares of SpaceX, trading under the ticker SPCX since its initial public offering last month, did what they have done for weeks: fell anyway.
The stock closed the week down 51 percent from the peak it touched in the first days after the IPO, a collapse that has erased the euphoria of the listing and replaced it with the arithmetic of a company whose valuation ran ahead of its business. The launch, impressive as it was, was not the problem. The problem is the price investors paid for the shares in the first place.
The IPO was one of the most anticipated in years, drawing demand from investors who saw SpaceX as the rare company combining a rocket monopoly, satellite revenue and a path into the AI economy. The shares soared in the opening sessions as retail enthusiasm met constrained supply. Then the float grew, the enthusiasm cooled, and the stock began the slow, grinding descent that has now cut its value in half.
Analysts who cover the stock have been warning that the post-IPO price embedded assumptions the business could not support. One calculation, cited by analysts in the weeks since the listing, strips out the value of the company’s AI-related businesses and arrives at a share price near $100 — a level that would represent another sharp decline from the current price. The analysis is blunt, and it is a minority view, but it has given the sellers a rationale and the buyers a number to fear.
The AI angle is the twist in SpaceX’s story. The company has been building a satellite constellation that provides global connectivity, and it has positioned that network as infrastructure for the AI economy — data pipelines, remote compute, edge connectivity. Investors who bought the IPO at the peak were paying for that story; the analysts who value the AI business at zero are saying the market should pay for the rockets and the satellites, and treat the AI ambitions as upside rather than price.
Starship’s successes have not helped because the stock’s problem was never operational. The test flights have been improving steadily, the cadence is accelerating, and the company’s launch monopoly is intact. What has broken is the price: the market repriced the shares from the scarcity of the IPO to the reality of the float, and no amount of successful engineering has been able to reverse that repricing.
The fundamentals, by most measures, are strong. SpaceX launches more than any competitor by a wide margin, its Starlink constellation generates real subscription revenue, and its backlog of government and commercial contracts is deep. The company that went public last month is, by any operational measure, the most successful launch company in history. The stock price, at least since the peak, has been a different story.
The next catalyst is structural rather than operational. SpaceX is expected to join the Nasdaq-100 index — and with it the QQQ exchange-traded fund, one of the most widely held funds in the world — in the coming rebalance. Index inclusion brings passive buying: funds that track the index will have to own the shares, and that demand could provide a floor under the price. The company’s supporters are counting on it; its skeptics note that passive flows support the price but do not validate the valuation.
The broader lesson investors are drawing from the episode is about the shape of modern IPOs. Deals now price scarce supply against massive retail demand, and the opening pop — once seen as a sign of success — has increasingly become a signal to sell. SpaceX’s trajectory from peak to half-price in weeks is an extreme version of a pattern that has played out across the market’s most hyped listings.
The decline also tests a long-held assumption about SpaceX as an investment. For years, private-market investors paid premium valuations for access to a company that almost never sold shares, on the theory that the stock’s scarcity justified the price. The public market has now delivered a different verdict, and the lesson for the company’s early backers is uncomfortable: the liquidity they waited for has come with a markdown attached.
For the company, the stock decline is a complication rather than a crisis. SpaceX does not need the public market for capital — its operations generate cash, and its contracts are funded — and the founders’ long-term ambitions were never tied to the daily price. But a halved stock complicates employee compensation, acquisition currency and the ability to fund the next generation of programs. The near-flawless Starship flight was the right kind of news; it just arrived at the wrong time in the stock’s story.
