SpaceX's Sept. 9 Unlock Scare Is Overblown — But the Shares Still Aren't Cheap

Sept. 9 is circled on SpaceX's charts for a reason that has nothing to do with the business. On that day, 319 million shares held by pre-IPO insiders become eligible to sell — the latest step in a staggered lockup release, layered on top of more than a billion shares that already unlocked in August. For a stock with one of the thinnest floats on the Nasdaq, the market has turned that block of stock into a cliff. The scare is understandable. The evidence keeps saying it is wrong.

The August experiment the headline missed

SpaceX went public on June 12 at $135, opened at $150, and pulled off the largest IPO in history — roughly $86 billion raised, nearly three times the previous record set by Saudi Aramco. But it listed only a sliver of itself. Roughly 5% of shares were freely tradable at the IPO, versus the 10% to 25% that is typical, and almost everything else was held inside a lockup. That tiny float is the root of every unlock scare that followed.

Then came the natural experiment. On Aug. 6, 911.5 million shares — more than the entire IPO float — became eligible to sell. Investors braced for a flood. The stock bucked higher. 319 million shares unlocked on Aug. 20, and again there was no cascade. By early September, the shares had reclaimed the $150 opening print.

The script keeps failing because "eligible to sell" is not the same as "sold." An unlock makes shares available; whether they actually hit the market depends on whether insiders choose to sell, at what price, and who is standing on the other side of the trade. This summer, a lot of buyers were.

A float being built back out, not shattered

Part of what absorbed that supply is mechanical and likely permanent. SpaceX joined the Nasdaq-100 in early July, which forced index funds to buy, and more index weight is in the pipeline. Morningstar recently called out the unusual setup: index funds set to buy more SpaceX shares just as insiders are finally free to sell. Passive demand has been meeting the supply head-on.

That is why Sept. 9 is best read as one rung of a long ladder rather than a single event. More unlocks follow later this September and into October. And the largest of all lands next summer, when Elon Musk's roughly 46% stake becomes eligible — the point at which the effective float jumps from about half the company to nearly all of it. The supply story is a year-long grind toward a normal float, not a panic on one Wednesday.

What the unlock headlines do not answer: the price

Here is the uncomfortable part. All of this is supply mechanics — trading, not value. And once you set the unlock noise aside and ask what the business is actually worth, the answer is far less reassuring.

As of early September the stock trades near $148, putting the market value around $1.95 trillion. Its debut quarter was strong: revenue grew 92% to $7.8 billion and the net loss narrowed to $541 million, momentum driven largely by Starlink and launch. But that price still works out to roughly 85 times trailing sales, on a company with a negative operating margin and about $43 billion of trailing capital spending as it builds out new capacity.

In other words, this is not a battered contrarian bargain the market has underpriced. It is the reverse: investors are paying a huge premium for a Starlink-at-scale future that has not fully arrived. The unlock fear is arguably overblown — the evidence keeps confirming that. But the valuation is not cheap, and at that multiple the burden of proof sits with the bulls, not the bears.

What Sept. 9 actually asks of you

Do not treat it as a crash trigger — the unlock data has now disproven that mechanical read three times in a month. And do not mistake a post-unlock bounce for a bargain. The unlock dates decide how the shares trade while the float is built back out; the valuation test decides whether a $1.95 trillion price can hold. That test runs on quarters of Starlink growth and narrowing losses, not on a single date in September. The calendar event will grab attention. The earnings will decide the case.
