SpaceX's First Earnings Met Its First Unlock: 911 Million Shares Hit a Stock Already Down 50%

In June we argued that chasing IPOs on day one is a loser's game. The eight weeks since have been an unusually clean natural experiment.

Here is the sequence. SpaceX (SPCX) priced its IPO at $135 and began trading on the Nasdaq on 12 June 2026. Within four days it hit an intraday high of $225.64, closing as high as $211.39 on 16 June. On 4 August it reported its first quarterly results as a public company. By the close on 5 August the stock was at $108.27 — below its IPO price, and more than 50% off the June high.

Then, on 6 August, the first tranche of insider shares unlocked.

What actually broke the stock

The earnings report did most of the damage before the unlock arrived. The number that mattered: capital expenditure came in at more than twice revenue.

That is not automatically damning for an infrastructure business — you cannot build launch capacity, a satellite constellation, and ground infrastructure out of operating cash flow alone. But it collided badly with a valuation that had been set at peak enthusiasm. A company spending two dollars of capex for every dollar of revenue is, structurally, a company that will need to keep raising capital. Investors who had modelled a profitable near-term rocket business found themselves holding a capital-intensive buildout instead.

If you want a framework for reading a report like this yourself, our guide to reading an earnings report in ten minutes covers exactly which four lines to check first. Capex versus revenue is one of them.

The lockup mechanics are the real lesson

Most IPOs use a simple 180-day lockup: insiders can't sell for six months, then everyone can. SpaceX used a staggered structure instead, designed specifically to avoid a single cliff of supply.

Under that structure, up to 911.5 million shares became eligible to trade on the second full trading day after the first earnings release — roughly 20% of the 180-day block. The design also included an early-release sweetener: an additional ~10% could have unlocked early if the stock had traded at least 30% above the $135 IPO price (i.e. above $175.50) on five of the ten trading days before earnings. It didn't come close, so that tranche stayed locked.

Now hold those numbers next to the float. Only roughly 640 million shares were actually trading before the unlock. The first tranche alone was larger than the entire existing float.

That is the whole story. A stock with a deliberately tiny public float — around 4–5% of roughly 13 billion shares outstanding — will trade at whatever price a very small number of buyers and sellers agree on. It is not a price discovered by the market; it is a price discovered by a fraction of the market. Every unlock drags that price closer to what the full shareholder base thinks the company is worth.

Short sellers understood this early: bearish positioning reached roughly a third of the public float ahead of the unlock.

What's still coming

The staggered schedule isn't finished. The remainder of the 180-day block is scheduled to free up through 8 December 2026, and Elon Musk's own stake — roughly 6.4 billion shares — is locked for 366 days, until 12 June 2027, with no early-release provision.

In other words: the largest supply events are still ahead of the stock, not behind it.

The transferable lesson

You do not need an opinion on SpaceX to take something from this.

When you buy any recent IPO, check three things before the story: the size of the public float as a percentage of shares outstanding, the lockup schedule, and the capex-to-revenue ratio. Those three numbers would have told you, in June, almost everything the last eight weeks revealed — without needing to forecast a single launch.

The most common beginner mistakes almost all share a root cause: buying the narrative before checking the structure. This was a textbook example, and it happened in public, in eight weeks.
