What Happened to SpaceX IPO Lockup?

For years, the prospect of a SpaceX Initial Public Offering (IPO) was a subject of intense speculation, with CEO Elon Musk often stating the company would remain private until its Starlink satellite internet service achieved predictable revenue. This changed dramatically in late 2025 and early 2026, culminating in SpaceX's historic public debut.

SpaceX officially went public on June 12, 2026, listing on the Nasdaq exchange under the ticker symbol SPCX. The IPO was monumental, raising approximately $75 billion and valuing the company at an astounding $1.77 trillion, making it the largest initial public offering in financial history. This valuation positioned SpaceX as one of the world's most valuable public companies, and briefly elevated Elon Musk to the status of the world's first trillionaire. The company's S-1 prospectus, filed publicly on May 20, 2026, detailed its diverse business lines, including launch services, the rapidly growing Starlink network, and the recently acquired xAI artificial intelligence venture, which was merged into SpaceX in February 2026.

Unlike a standard 180-day IPO lockup, SpaceX implemented a complex, tiered release schedule designed to manage the influx of shares onto the market and mitigate post-IPO volatility. Elon Musk, who retains significant control with 42% of shares and 82% of voting power, along with other 'certain significant investors,' agreed to an extended 366-day lockup period, preventing them from selling shares until June 13, 2027. This extended lockup for major stakeholders is seen as a positive signal, demonstrating long-term commitment and protecting the stock price.

For pre-IPO institutional backers and early venture capitalists, a performance-tied lockup framework is in place. They can unlock an initial 20% of their holdings on the second full trading day following SpaceX's Q2 2026 earnings release, which is anticipated in late July or early August 2026. An additional 10% can be sold if the stock trades 30% or more above its $135 IPO price (i.e., above $175.50) for at least five of the ten trading days preceding the earnings report.

SpaceX employees and core insiders, many of whom became paper millionaires post-IPO, also have a staggered release. Their vested Restricted Stock Units (RSUs) unlock in rolling 7% increments after 70, 90, 105, 120, and 135 calendar days following the June 12 IPO. An additional 28% will unlock after the Q3 2026 earnings report, with all remaining restrictions lifting at the 180-day mark, around December 8, 2026. This phased approach aims to provide liquidity to employees who have held private equity for years while preventing a single, large sell-off that could destabilize the stock.

As of July 3, 2026, the stock (SPCX) has experienced significant volatility since its debut, opening at $150 and closing its first day up nearly 19% at $161.11, but has since seen swings, trading around $170.86 as of July 1, 2026, with a 52-week high of $225.64. The upcoming unlock dates, particularly the Q2 earnings release and the subsequent employee tranches, are key events investors are monitoring for potential impacts on supply and price. The company's heavy investments in Starship development and AI infrastructure, alongside its Starlink profitability, continue to be central to its financial narrative.
