The pop reflects structural demand as much as enthusiasm: only 4% of shares are public, the offering was oversubscribed four times, and SpaceX successfully pressured the firms behind stock market benchmarks like the Nasdaq 100 to fast track its inclusion.
Elon Musk crossed into trillionaire territory before noon on Friday, when SpaceX opened on the Nasdaq stock exchange at $150 a share, well above the $135 price set the previous night. The debut vaulted the rocket company into the ranks of the six most valuable public companies in the United States, with a market capitalization near $2.3 trillion by midday, even as the mechanics of the listing made that number less a verdict on underlying value than a product of how the deal was structured.
SpaceX began trading on the Nasdaq on June 12, 2026, opening at $150 per share, about 11% above the $135 IPO price set Thursday night. Intraday trading pushed the price to a high of $176, lifting the company's market cap to nearly $2.3 trillion. That briefly put SpaceX ahead of every U.S. public company except a handful of the largest tech and oil giants, a position that will likely shuffle as the stock finds a clearing price through the rest of the session.
The pop was amplified by a set of structural features that stack the demand side of the trade. Only about 4% of SpaceX shares are trading in the public market, the so-called float, according to the offering details reported by TechCrunch. The rest sit with early investors and employees. The IPO was oversubscribed 4x, meaning institutional investors wanted four times as many shares as were available, per Bloomberg reporting cited by TechCrunch, leaving many funds to buy in the open market after the listing. And SpaceX successfully lobbied index providers, including the one governing the Nasdaq 100, to change their inclusion rules, compressing what is normally a months-long process into a few days. Each of those mechanics adds buying pressure that is independent of how the market values the underlying business.
The wealth created on day one is concentrated in a small number of hands. At the $150 opening price, Musk's stake made him the first person in history with a net worth above $1 trillion, a threshold the world's billionaires have chased for years. Venture capital investors who backed SpaceX in private rounds also took paper gains that turned into something closer to liquidity. Founders Fund's reported $600 million investment is now worth more than $50 billion at the IPO price. Andreessen Horowitz's stake is worth more than $10 billion. Sequoia's position is valued above $20 billion. These figures, drawn from the offering disclosures summarized in TechCrunch's coverage, will change as the stock moves and lockup periods expire.
Below the billionaire layer, the listing minted thousands of new millionaires inside SpaceX itself. Roughly 4,400 current and former employees held equity that crossed the seven-figure mark on day one, and about 400 of them crossed into a higher tier: centimillionaires, the term used in private wealth reporting for individuals with a net worth above $100 million. The count is drawn from filings and reporting cited by TechCrunch and reflects a broader shift in late-stage tech. As private companies stay private longer, the ranks of employees holding paper wealth above traditional milestones have grown, and a public listing is the moment those balances stop being theoretical.
The question for the weeks ahead is whether the $2.3 trillion cap holds once the float begins to widen. Lockup expirations will release more shares to the market, and index demand, which is mechanical and front-loaded, will taper as the stock works its way through the inclusion schedule. The Bloomberg-cited 4x oversubscription suggests there is genuine institutional appetite behind the move, but the same mechanics that lifted the price on day one are the ones most likely to test it later.
