The calendar flipped to August 6, and the lockup that had kept nearly a billion SpaceX shares off the market expired at midnight. By morning, roughly 911.5 million shares held by insiders, employees and early investors were eligible to trade, adding a fresh overhang to a stock that had been hammered the day before. SpaceX’s first earnings report since its initial public offering, the largest in history, had done the damage, and the expiration of the lockup now raises the question of how much more supply the market will absorb.
On Tuesday, the company reported its first results as a public company: revenue roughly doubled from a year earlier, a headline number that would once have been cause for celebration. But the report also disclosed a surge in capital spending tied to AI and satellite infrastructure, and investors sold first and asked questions later. Shares fell as much as 12% in early trading before stabilizing. The selloff left the stock below the levels where many recent buyers had entered, and the size of the unlock means the coming weeks will test whether the selling that started on Tuesday has more room to run.
Lockup expirations are among the most watched events in the life of a newly listed company. The agreements that keep insiders from selling in the months after an IPO exist to protect the offering, but they merely delay supply rather than eliminate it. When the restrictions lift, holders who have waited months for liquidity often sell at least a portion of their positions, and the size of the unlock matters enormously. By that measure, SpaceX’s is one of the largest in memory: 911.5 million shares represents a meaningful slice of the company’s outstanding stock, and even a modest rate of insider selling would add millions of shares of daily volume.
The context makes the unlock more delicate. SpaceX’s listing was the largest initial public offering in history, and the stock’s path since then has been shaped by two forces pulling in opposite directions. On one side is the company’s operational momentum: launch cadence, satellite revenue and the expansion of its government and enterprise business have all grown at a pace few companies match. On the other is the scale of its spending, which the first earnings report laid bare. The AI capital expenditure that spooked investors on Tuesday is part of a broader program to build computing capacity that SpaceX sees as essential to its long-term ambitions, but markets, as the reaction showed, are not always patient with such programs.
Forbes and Yahoo Finance, among others, used the moment to make a pointed observation: the real secondary-market test of the largest IPO in history is only beginning. The float, they noted, has been small relative to the company’s total value, and the lockup expiry is the first moment when a broad group of insiders can act on their convictions. The arithmetic is simple: if even a fraction of those 911.5 million shares finds its way into the market, the supply will need to be matched by buyers who believe in the long-term story.
Whether that buying appears depends on the story investors tell themselves about SpaceX’s earnings, analysts said. The revenue doubling was real, but so was the spending that accompanied it, and the market’s reaction suggests investors are weighing the two against each other rather than celebrating either in isolation. The stock’s behavior in the coming weeks will be a test of conviction: holders who see the AI and satellite investment as a foundation for decades of growth will hold, while those who see it as a black hole will use the lockup expiry as their exit.
Insider selling is rarely uniform, traders pointed out. Employees who received shares as compensation often sell soon after an unlock to diversify, while founders and early investors typically hold longer, and large institutional holders frequently use the expiry to adjust positions rather than exit them. The shape of the selling curve, more than its existence, will determine how much pressure the stock faces. SpaceX has also taken steps common to companies in its position, including making registration statements effective and allowing insiders to trade under prearranged plans, which smooths the flow of supply over months rather than dumping it in a single day.
The broader market is watching too. A deep slide in SpaceX would be felt beyond its own holders: index funds, institutional portfolios and the sentiment of the technology complex generally would all take note. Conversely, a smooth absorption of the unlock would bolster the case that the AI-driven spending cycle can coexist with functioning capital markets. Either way, the next few months will be a live experiment in how the largest public offering in history behaves when its shareholders are finally free to vote with their feet. The lockup has expired, the shares are free, and the market is about to learn what they are worth.
