SpaceX (SPCX) Stock Wobbles Again as $101 Billion Share Lockup Expires - Just Two Days After Earnings

What Happened

SpaceX (Nasdaq: SPCX), which went public in June, is back in the headlines for a very different reason than its earnings report. We previously covered how the company's first quarterly report as a public company - released after the close on August 4 - triggered an 8%-plus after-hours drop even though revenue jumped 92% year over year. That shock hadn't even fully faded before a second, unrelated pressure point hit: on August 5, shares slid more than 13% in a single session to close at $108.27, and by the August 6 premarket, the stock was seeing renewed weakness as the lockup expiration added fresh supply-side pressure.

This second wave of selling has a different root cause: a share lockup expiration. August 6 marks only the second full Nasdaq trading day since SpaceX's listing, and it's the date on which up to 911.5 million Class A shares become eligible to be released from certain lock-up and market-standoff restrictions. At the most recent premarket price of roughly $111.50, that block of newly tradable shares carries a notional value of approximately $101.6 billion - a figure large enough, relative to the company's market capitalization, that even partial selling from insiders could meaningfully pressure the stock.

Here's how the price action has unfolded:

• August 4, after earnings: shares fell more than 8% in after-hours trading
• August 5, regular session: the stock gave back most of a prior rally, sliding over 13% and closing at $108.27
• August 5, intraday range: a wide swing between a high of $117.50 and a low of $106.66
• August 6, premarket: renewed weakness as the lockup expiration added to selling pressure

Against the $135 IPO offer price, SPCX now sits nearly 20% below where it started trading. Measured from its post-IPO intraday high of $225.64, the stock has lost more than 40% of its value. In other words, this lockup event is landing on a stock that had already absorbed a substantial decline - which is a big part of why the market is watching it so closely.

Why a Lockup Expiration Moves the Stock - The Mechanics of Float and Supply

To understand why a lockup expiration matters, it helps to understand what happens right after an IPO. When a company goes public, insiders - founders, employees, and pre-IPO investors like venture capital firms - typically agree not to sell their shares for a set period, usually 180 days. During that window, the number of shares actually available to trade (the "float") is far smaller than the company's total share count. That artificially tight supply is part of why newly public stocks can rally on relatively modest buying demand - there simply isn't much stock available to absorb it.

The trouble starts when that restriction lifts. Even before any insider actually sells, the mere knowledge that a much larger pool of shares could hit the market tends to push investors to sell preemptively, anticipating future price pressure. This is a well-documented pattern across large IPOs - Meta (then Facebook) is a frequently cited example of a stock that swung sharply around its own lockup expiration. The signal that supply is about to expand is often enough to move the price on its own, independent of whether insiders follow through with actual sales.

SpaceX's situation is more complicated than a typical single-date lockup. According to analysis from Bernstein, SpaceX's unlock structure isn't the standard "one deadline at 180 days" format - it's what the firm calls an "unusually complex scheme with nine main unlock points instead of one traditional 180-day expiry." August 6 is only the first major release date in that sequence; several additional waves of shares are scheduled to become tradable over the following months. The most dramatic step comes in December, when the total number of shares available to trade is expected to jump to 5.33 billion - dwarfing what's being released this week. That means investors face not a single, one-time supply shock, but a recurring series of them stretching out for months.

This structure layers a supply-side headwind onto SpaceX's stock that has nothing to do with its underlying business performance. It's worth noting that the earnings report itself wasn't purely a fundamentals story either - the company's 92% revenue growth was overshadowed by concerns over more than $18 billion in AI-related capital expenditure for the quarter. With that fundamentals debate still unresolved, the lockup expiration adds a second, largely independent source of pressure, and the two concerns compounding at the same time helps explain why the selloff has extended well beyond the initial earnings reaction.

It's also worth being precise about what a lockup expiration guarantees and what it doesn't. Shares becoming eligible to trade is not the same as insiders actually selling them - long-term-oriented institutional holders or founders may choose to hold. But the theoretical possibility of a much larger supply hitting the market is itself enough to raise volatility, which is why traders tend to treat these dates as risk events regardless of how much actual selling ultimately occurs.

What to Take Away From This

• Check the lockup schedule before investing in a recent IPO. Prospectuses and SEC filings disclose when lockup restrictions expire and how many shares are affected. Knowing these dates in advance helps you distinguish a scheduled supply event from a fundamentals-driven selloff, rather than reacting to it as fresh bad news.
• Float size is an independent variable that can move a stock on its own. A company's business can be completely unchanged and its stock can still swing sharply simply because more shares suddenly become tradable. Watching share-structure events matters just as much as watching earnings.
• A multi-stage unlock structure means volatility isn't a one-time event. SpaceX's nine-point unlock schedule, with the largest wave still months away in December, means both short-term traders and long-term holders should mark future unlock dates on a calendar and size positions with that recurring risk in mind.
• Separate the causes of a decline before reacting. Disappointment over earnings and pressure from a supply-side unlock are different problems with different timelines and different appropriate responses. When both hit at once, it's worth trying to estimate how much of the move each one explains rather than treating the combined drop as one undifferentiated signal.
• Recently listed stocks carry outsized volatility in their first six to twelve months. A short trading history combined with a string of scheduled unlock events tends to produce far less predictable price action than a mature large-cap. Size any recent-IPO position with that added unpredictability in mind.
