SpaceX's Locked 911.5 Million Shares Freed by Its First Earnings

A stock's price has less to do with the company than most people assume, and a great deal to do with how many of its shares can be sold on any given day. Textbooks tie price to the future. Markets look first at the supply sitting in front of them.

That is precisely what has been happening at SpaceX since it came public on June 12 in the largest IPO in market history. Of roughly 13 billion shares outstanding, only about 639 million — call it 5% — reached the market. Everything else was locked.

On Thursday morning, August 6, the first tranche of that lock comes off. 911.5 million shares become sellable. That is enough to raise the tradable share count roughly two and a half times overnight.

Different outlets put the released value anywhere between $116 billion and $123 billion. The spread is not an arithmetic error — everyone is multiplying the same 911.5 million shares by a different day's price. As the stock falls, so does the dollar value of the unlock. That is the first clue to the whole story.

The Calendar Didn't Open It. The Earnings Report Did.

IPO lock-ups are normally tied to the calendar: 180 days pass, the lock comes off. SpaceX did it differently.

SpaceX tied its lock-up not to a date but to an event: the company's first earnings release as a public company. That report landed after the close on August 4. The contract pointed to the second full trading day afterward. That day is August 6.

The company's stated rationale sits in the prospectus: staging supply over time to "avoid major disruptions to normal market supply and demand." The intent is reasonable. The effect is that the unlock lands immediately after the single day the company generates the most volatility.

The 30% Clause That Didn't Trigger

The contract contained a second door. Had the stock closed more than 30% above the IPO price — above $175.50 — on five of the ten trading days before earnings, an additional 10% of restricted stock, roughly 455.8 million shares, would have been released alongside the 20% tranche.

It never came close. The stock closed August 4 at $125.33.

The inversion here is worth sitting with. Lock-up agreements are typically built this way: strength pulls supply forward, weakness holds it back. SpaceX's weakness is what spared it 455.8 million shares of additional supply. A bad month in the market kept one of the doors shut.

The Price of Scarcity

This is where the mechanism lives. In mid-June SpaceX traded as high as $225.64 intraday, with a closing peak of $201.80. It closed August 5 at $108.27 — less than half its peak.

It is easy to look at that and conclude the company deteriorated. But over those same weeks revenue grew, contracted backlog expanded, and subscriber counts rose. What changed was not the company. What changed was how many hands the stock sits in.

The proportions at SpaceX are close to exactly that. The IPO put 639 million shares into public hands; Thursday morning another 911.5 million become eligible to join them.

The second line is a ceiling, not a forecast. Where the real number lands depends on what holders choose to do.

Eight Days of Volume

There is a second calculation worth working through: measuring the released supply against how much the market can absorb in a day.

SpaceX trades roughly 115 million shares on an average day. If all 911.5 million released shares hit the market, that would represent eight full days of total volume — and that assumes nobody else trades at all during those eight days. No market absorbs supply like that at an orderly price.

But all of it will not hit the market. An unlock grants permission; it does not create an obligation.

Who Actually Sells

The holders of locked stock are not one group, and their cost bases differ sharply. That distinction is the real variable behind how many shares arrive.

Employees. They accumulated stock through years of compensation, at very low cost. Most of their net worth now sits in a single company. This group's reason to sell is not a price view but diversification — the need to spread risk.

Venture funds. Funds have finite lives and are obligated to distribute to their own investors. The IPO is when that distribution happens. The decision is often driven by the fund's clock, not the share price.

Early investors. Those who came in years ago hold stock at a fraction of today's price. Someone who says "I won't sell below $135" does not say it if they bought at $8.

This is why Morningstar analyst Nicolas Owens is blunt about it: because sellers carry low cost bases and have waited a long time, he believes "most of the available shares will come to market."

Earnings: Revenue Nearly Doubled, Spending Nearly Tripled

The report that opened the lock was a hard day in its own right.

SpaceX posted second-quarter revenue of $7.8 billion against a $6.8 billion estimate. EBITDA came in at $3.5 billion versus $2.1 billion expected. Revenue grew 92% year over year. AI revenue more than tripled to $2.6 billion. Starlink added 1.7 million subscribers. All of that cleared the bar.

Then came the spending line. Quarterly capital expenditure was $18.4 billion, several times what analysts had modeled. Of that, $15.8 billion went to AI infrastructure — against $7.7 billion in the first quarter. The company pointed to roughly $65 billion of capex for the full year; consensus had been near $50 billion.

CFO Bret Johnsen defended it, saying new compute deployments now pay back in under a year and that the company is on track for a $100 billion annualized revenue run rate by year-end. The same presentation also showed the AI business still losing money at the operating level and the company running deeply free-cash-flow negative.

That is why the stock was sold hard the next day. And the decline had nothing to do with the sector:

The intraday loss deepened into the close: SpaceX finished August 5 down 13.6% at $108.27, roughly 20% below the IPO price.

What the bars say is straightforward: space and satellite names had an ordinary session. What was being sold was not a sector but one company's spending plan and the lock coming off on Thursday.

The charts below are live; they show not the event itself but where the price stands looking back from today.

For comparison against the broader market:

Fifty-Five Days, in Order

The fourth line is the least discussed part of the story. The unlock date was known weeks in advance, and the market positioned accordingly.

Who Is on the Other Side

It would be a mistake to treat the supply pressure as one-directional. The unlock was visible for weeks, and the market prepared for it — aggressively.

As of July 29, short interest in SpaceX stood at 219.3 million shares, roughly 34% of the float. On June 23 the figure was 40 million. It grew fivefold in five weeks.

That number carries two meanings, and both are true. First, a large group has bet that the unlock drags the price down. Second, and less discussed: every share sold short must eventually be bought back. So against Thursday's incoming supply sits a pre-built pool of 219.3 million shares' worth of compulsory buyers.

What's Left

Thursday is not an ending. It is the first step in a long schedule. The lock comes off in slices, not at once.

These percentages are approximate and vary slightly between sources; the binding document is the company's prospectus on file with the SEC.

The last row frames the whole story. Musk's shares — 42% of the equity, 85% of the voting power — sit under a 366-day lock with no early-release provision. Control of the company is not in question until June 2027. What becomes sellable on Thursday is not control. It is circulation.

The Lesson: The First Price Is Scarcity's Price, Not the Company's

Whatever you think of SpaceX's future, the lesson here is independent of it.

The price a company shows in its first weeks as a public company is usually not a price struck on the whole company. It is struck on a 5% slice, and it embeds the competition among everyone who wants a piece of that slice. As the lock comes off, the competition ends — and the price starts showing what the same company is worth across a much wider ownership base.

The second lesson is narrower but more practical: unlock dates are never a surprise. They are published in the prospectus months before trading begins. There is a large constituency in the market that tracks them — short interest going up fivefold between June 23 and July 29 is the proof.

Ending up on the uninformed side of that is rarely about missing information. It is about not looking.

This piece reflects reporting from Forbes, CNBC, Yahoo Finance, Morningstar, The Motley Fool and 24/7 Wall St. as of the August 5, 2026 close. The total value of the released shares and the size of the float differ between sources, chiefly because each uses a different day's closing price. The percentages in the unlock schedule are approximate; the company's SEC prospectus is the binding document.
