On Wednesday, SpaceX shares dropped almost 5 percent, the first losing session since the company went public five days earlier. A small thing, that drop, set against what had come before. In its opening week of trading, Elon Musk's rocket-and-satellite venture had climbed roughly 42 percent off an IPO price of $135 a share, a run so steep that by Tuesday's close the company carried a market capitalization of $2.66 trillion, according to CNBC. That figure briefly vaulted SpaceX past Amazon, and for a moment it edged ahead of Microsoft to rank as the fourth most valuable public company in the United States.
Then the air came out a little. A single down session does not undo the rally. It does, however, what every first red day does for a hot new listing: it reminds people that gravity applies to stocks too.
The number nobody on the rally was looking at
Here is the figure that complicates the celebration. SpaceX recorded a net loss of $4.9 billion across 2025, and the bleeding has not stopped: the most recent quarter alone added a further $4.28 billion to that tally. A company approaching $3 trillion in valuation is, by the plain arithmetic of its own books, losing money at a brisk clip. The investors who bid the shares up more than 40 percent in a few days are not buying current earnings. They are buying the prospect of them.
That distinction matters far more than any daily chart wiggle. A market cap near $3 trillion places SpaceX in the company of firms that print enormous, predictable profits quarter after quarter: Apple, Microsoft, the mature giants of American capitalism. SpaceX is not yet that kind of business. It is a company with two genuinely dominant franchises (the Starlink satellite-internet network and a fleet of reusable rockets that nobody else can match at scale) wrapped around a financial profile that still runs in the red.
Musk, for his part, has set the bar where the bulls want it. He posted on X over the weekend that SpaceX could reach something close to $1 trillion in annual revenue by 2030. Take that in for a moment. A trillion dollars in sales would put the firm in territory no company on Earth currently occupies. Whether it counts as a forecast, an aspiration, or simply Musk being Musk on a Sunday afternoon is left, as usual, to the reader.
Trading the story, not the spreadsheet
The skeptic's case was laid out plainly on CNBC's Squawk Box Asia by Peter Boockvar, who serves as chief investment officer at the firm One Point BFG Wealth Partners. Investors right now, he argued, are trading the narrative, the excitement, the man at the top, more than any income statement. At some point, he said, "the rubber meets the road," and the fundamentals have to catch up with the enthusiasm.
That is not the same as calling the rally fake. Boockvar allowed that if SpaceX delivers, the upside is real. His worry is one of timing and scale. The valuation is now so large that even strong execution might take years to justify the price tag investors have already paid. He guessed it would be "at least a couple of years" before the company could grow into the number the market has assigned it.
There is history to lean on here, and it cuts both ways. Amazon spent the better part of a decade as a punchline for analysts who could not square its share price with its persistent losses, and the patient ones were eventually vindicated many times over. Tesla, Musk's other headline act, went public in 2010 to widespread doubt and spent years as the most heavily shorted stock in America before becoming one of the great wealth-creation stories of the era. For every cautionary tale of a debut that fizzled, there is a counterexample of a money-losing company that grew into something extraordinary. The trouble for anyone trying to price SpaceX today is that you do not know which story you are in until it is over.
What Starlink actually has to do
Strip away the rocket spectacle and the case for the valuation rests heavily on Starlink. The satellite-broadband service has put thousands of small spacecraft in low orbit and signed up customers in places terrestrial networks never reached, from rural farms to ships at sea to, controversially, conflict zones. It is the part of the business that looks most like a conventional, recurring-revenue subscription company, and it is the engine most likely to bridge the gap between a $4.9 billion loss and Musk's trillion-dollar revenue dream.
The reusable rockets are the moat, the thing competitors cannot replicate. But launch is a lumpy, capital-hungry business, and it is far from obvious that it scales into the kind of high-margin cash machine that supports a $3 trillion price. Subscriptions do. So the bet embedded in the stock, whether buyers would put it this way or not, is that Starlink keeps adding customers fast enough, at good enough margins, to carry the whole enterprise into profitability while the launch side keeps driving the cost of putting hardware in orbit down.
None of that is guaranteed. Low-orbit broadband is getting more crowded. Amazon's own Kuiper constellation is one rival with deep pockets, and governments around the world have grown uneasy about depending on a single private network controlled by one mercurial founder. Regulatory friction, spectrum disputes, and the sheer cost of replacing satellites with short orbital lifespans all sit on the other side of the ledger from Musk's revenue projection.
Where the SpaceX stock story goes from here
A week of trading tells you almost nothing about whether a company is worth $3 trillion. It tells you what a crowd of buyers feels in the moment, and right now that feeling is a mix of conviction and adrenaline. Wednesday's 5 percent slide is the first hint that the crowd can change its mind, and on a stock priced for near-flawless execution, sentiment swings tend to land hard.
The thing worth watching is not the chart over the coming days. It is the next set of financials. If the quarterly losses begin narrowing and Starlink's subscriber and revenue figures climb along the curve that Musk's 2030 target implies, the bulls will look prescient and the early skeptics will look timid. If the losses persist while the valuation stays parked near the summit of the market, the questions Boockvar raised will not go away. They will get louder, and they will start arriving every ninety days, on schedule, when the company reports.
For now, SpaceX is the rarest kind of public company: one whose price is almost entirely a wager on a future that has not been written. The market has decided to believe. The books have not caught up. Somewhere in the years between those two facts sits the answer to whether this was a great IPO or merely an exciting one.
