NextFin News - SpaceX's stock survived its first earnings beat, but the harder test arrived two days later. On August 6, up to 911.5 million shares held by employees and early investors became eligible for sale - more than the roughly 639 million shares SpaceX put into public hands at its June 12 initial public offering. The unlock is not a one-day cliff. It is a staggered release scheduled to run through December, and it forces a question the market has not had to answer since the IPO: now that SpaceX shares can actually be traded, who wants to own them, and at what price?
The timing is deliberate and unforgiving. The first selling window opened just after the company's first quarterly report as a public company, which showed second-quarter revenue of $7.81 billion, ahead of the $6.93 billion analysts expected. Yet the stock had already told its own story. Priced at $135, SpaceX briefly touched $201.80 after its debut, then fell as low as $108.27 - a 43% drop from the peak and about 15% below the IPO price - before rebounding to around $148 by mid-August. The unlock does not change the business. It changes the market structure the business trades in.
The Mechanics of the Unlock: Scarcity Is Being Removed on Schedule
SpaceX went public with an unusually small float. Buyers were not valuing the entire company in a deep, liquid market; they were competing for a fraction of it. The 424B4 filing laid out a lock-up schedule that spreads supply over nearly a year rather than dumping it on a single day. The first tranche - 20% of the 180-day block - released after the second-quarter earnings report. From there, roughly 7% tranches unlock at fixed milestones measured from the June 12 listing: August 20, September 9, September 24, October 9 and October 24. A larger slice, about 28% of the block, becomes eligible after the third-quarter earnings report in late October, and the full 180-day restriction expires December 8. Elon Musk's roughly 6.4 billion shares remain locked for 366 days, until June 12, 2027.
The scale is what makes this unusual. SpaceX has about 13.1 billion shares outstanding. The first unlock alone could more than double the number of shares available for trading, and if a price-based early-release provision had been triggered, the public float could have tripled. "This time, it's a multiple of the shares outstanding that will make their way onto the market, not a fraction, so these lockups will be an interesting test of the commitment of early investors to stand by the company for the long haul," said Andrew Chanin, chief executive of Procure AM, which runs the Procure Space ETF.
It is important to be precise about what an unlock is not. The shares already exist. This is not dilution, and it does not put new cash into SpaceX's balance sheet. It is a transfer of liquidity: people who helped build and finance the company gain access to an asset they could not readily trade for years. But markets clear at the margin. It does not require all 911.5 million shares to be sold for the lock-up to matter. If even a modest portion of employees - many of whom hold company stock as a large share of their net worth - decide to diversify, that supply has to be absorbed by a float that was priced in scarcity.
There is a reason the schedule looks like a staircase instead of a cliff. IPO lock-up expirations have a well-documented pattern: stocks tend to drift lower in the window around lock-up expiry, and the effect is strongest when the float is thin and the valuation is rich. The logic is mechanical - supply that was contractually withheld suddenly becomes eligible, and the holders most likely to sell are the ones with the least information about the company's future. SpaceX's bankers staggered the releases precisely to avoid a single-day disorderly auction. The trade-off is that the overhang does not disappear; it stretches out, and the market has to price it for months.
The Price Already Discounted the Bad News - and Then the Shorts Ran Out of Bullets
Here is the counter-intuitive part. The market did not wait for the unlock to reprice SpaceX. The 43% decline from the post-IPO peak happened before the first shares became eligible. By the time the lock-up opened, the stock was already trading about 15% below its IPO price, and short interest had built aggressively: S3 Partners estimated short interest peaked at 34% of publicly traded shares, before falling to about 11% by mid-August as the stock rebounded.
"Shorts that wanted to short are out of bullets," said Ihor Dusaniwsky, managing director of predictive analytics at S3 Partners. "Only so much money you can put into a trade."
That dynamic cuts both ways. The short-covering rally that lifted SpaceX back above $135 in mid-August shows how a thin float can amplify moves in either direction. But it also means the easy bearish trade - simply betting that the unlock would push the stock down - was largely positioned before the event. The remaining question is whether the sellers who now have the right to sell actually want to sell at these levels.
Some may not. Selling below the $135 IPO price is psychologically and financially unappealing for holders who bought in private rounds at far lower valuations but anchored to the public mark. Employees receiving equity compensation may diversify a portion and hold the rest. Early venture investors may stagger their exits rather than flood the market. The staggered schedule itself is designed to prevent a disorderly rush: if every tranche were eligible at once, the December 8 expiry would be a single-day supply shock instead of a nine-month absorption test.
There is also a reflexive layer the market is only beginning to price. SpaceX's unlock is the largest test yet of whether the willingness of investors to pay extra for exposure to the most visible entrepreneur in technology survives actual liquidity. The same dynamic will repeat, at much larger scale, when Musk's own 6.4 billion shares unlock in June 2027. Every tranche between now and then is a data point for that question.
The Real Story Is Not the Lock-Up: It Is What the Valuation Requires
The unlock is a mechanism. The valuation is the thesis. At a market capitalization that briefly approached $1.8 trillion, SpaceX was priced ahead of Tesla, Meta and Walmart - a premium that assumes not just success, but success on a scale few companies in history have delivered. The lock-up does not create that burden. It simply gives the market more opportunities to reassess it.
The foundation of the valuation is Starlink. In its prospectus, SpaceX disclosed that the satellite-internet unit generated $11.39 billion in revenue in 2025, or 61% of total sales, and produced $4.42 billion of operating income - the company's only profitable segment. Subscriber count surpassed 12 million by June. The economics improve as the constellation is built out: the cost base shifts from heavy launch capex to maintenance and ground infrastructure, while subscription revenue compounds. That is why Starlink funds Starship, not the other way around.
But the growth the market is paying for is not all Starlink. On the second-quarter earnings call, CFO Bret Johnsen said SpaceX is on pace to reach $100 billion in annualized recurring revenue by the end of the year. Analysts at Deutsche Bank called that "likely very achievable" - even though the second-quarter run-rate was only about $31 billion. The bridge to $100 billion depends heavily on the company's artificial-intelligence and data-center business, including the roughly $60 billion acquisition of coding-software company Cursor, which is expected to close in the third quarter. That is a different business, with different economics and different competitors, wrapped into a single ticker.
And it is expensive. SpaceX reported $10.1 billion of capital expenditures in the first quarter, of which $7.7 billion was AI-related. Analysts expected second-quarter capex of $13.2 billion. For context, consensus estimates for the first earnings report ranged from a loss of $1.26 per share to a profit of $0.33 - an unusually wide dispersion that shows how little agreement there is on what this company actually earns. Phillip Capital took the rare step of issuing a sell rating with a $75 price target, citing large losses and negative cash flows expected to persist until at least 2030. Morningstar has also rated the stock a sell.
The second-order implication is where the unlock becomes more than a technical event. If the stock remains under pressure through the autumn tranches, the cost of capital for SpaceX's most ambitious projects rises - Starship development, the AI data-center buildout, and the Cursor integration all depend on an equity price that keeps the balance sheet strong. A lower share price does not force the company to slow down, but it makes every dollar of expansion more dilutive to existing holders and raises the hurdle for what counts as an acceptable return. The lock-up, in other words, is not just a test of investor commitment. It is a test of how much ambition the public market is willing to fund.
Cyclical Pressure Meets Structural Ambition
Is the unlock a cyclical headwind or a structural problem? The answer is both, and separating them matters.
The liquidity wave is cyclical. It is a calendar-driven supply event with a known endpoint. IPO lock-up expirations routinely pressure stocks in the days around the expiry, and the effect is strongest when the float is thin and the valuation is rich. But the pressure is mean-reverting by construction - once the shares are absorbed, the overhang is gone. The December 8 full expiry and the June 2027 Musk expiry are the two remaining calendar events, and both are already known to the market.
The valuation, by contrast, is structural. A company trading at more than 100 times revenue cannot rely on scarcity to defend its multiple forever. Scarcity is a market-structure premium; it is not a moat. What defends the multiple is whether Starlink's subscription growth holds, whether the AI investments generate returns, and whether Starship turns launch economics into a durable advantage. If those drivers work, today's unlock will look like a footnote. If they do not, no lock-up schedule can support the price.
The strongest counter-thesis is simple: SpaceX is not overvalued; it is under-traded. The Uber comparison - a company that transformed an industry, attracted overwhelming demand, and still left IPO buyers underwater for years - is the cautionary tale. But SpaceX owns assets that would be exceptionally difficult to replicate: a reusable launch franchise, a global satellite network with more than 10,000 satellites in orbit, and a customer base spanning consumers, aviation, maritime and government. A premium is justified. The mistake is assuming a premium has no limit simply because the company is exceptional.
The falsifying signal is specific. If SpaceX reports Starlink subscriber net additions slowing materially while AI capital expenditures stay above $10 billion a quarter without visible revenue contribution, the growth narrative that supports the multiple breaks - and the unlock tranches become exit ramps rather than entry points. Watch the customer mix most of all: aviation and maritime contracts generate revenue an order of magnitude higher per account than residential subscriptions, and a shift toward lower-margin consumer adds would show up in average revenue per user before it shows up in total revenue.
Who Benefits, Who Is Exposed
The unlock creates asymmetries across the market, not just in SpaceX itself. Short sellers who positioned early have already taken much of their profit; the ones still in the trade are exposed to a short squeeze if selling proves lighter than feared. Long-only investors who missed the IPO now get repeated opportunities to establish a position at prices well below the post-IPO peak, but they inherit a stock whose valuation still assumes near-flawless execution. Employees and early investors gain liquidity they have waited years for - and with it, the temptation to concentrate risk in a single name just as the company's execution window narrows.
There is also a sector-wide read. SpaceX's dominance has been so complete that capital has spilled into the nearest available alternatives. If the unlock forces a broad de-rating of the space name at the center of the complex, the valuation umbrella shrinks for smaller launch and satellite companies too. If the absorption is orderly, it validates the entire sector's public-market footing.
What Investors Should Watch Next
The near-term path runs through the remaining tranches. The August 20 and September 9 releases are small enough to absorb if selling is orderly. The late-October tranche, tied to the third-quarter report, is the next meaningful test - roughly 28% of the 180-day block becomes eligible at once. The December 8 full expiry is the largest single supply event before Musk's shares unlock in June 2027.
Short-term, the stock is a liquidity instrument: thin float, elevated volatility, and a short-interest profile that can fuel sharp moves in both directions. Medium-term, the fundamentals dominate - Starlink's subscriber growth and customer mix, AI spending discipline, and launch cadence. Long-term, the question is structural: whether SpaceX can convert its launch and satellite advantages into cash flows large enough to justify a valuation that already assumes perfection.
The base case is orderly absorption. The staggered schedule, the psychological resistance of selling below the IPO price, and the company's genuine competitive advantages argue against a disorderly collapse. The downside case is a slow grind as each tranche reminds the market how much supply remains. The upside case is that the unlock proves lighter than feared, short-covering extends, and the $100 billion revenue target starts to look credible.
The unlock is not the story. It is the mirror. SpaceX's shares were priced in a market with almost no supply; now the market has to decide what they are worth when there is plenty. The lock-up schedule tells investors exactly when they will get another chance to answer.
