SpaceX sold stock to the public for the first time on June 12, 2026, in what turned out to be the largest initial public offering in history. The company offered 555.6 million shares at $135 each, raising approximately $75 billion. On its first trading day, the stock closed at $160.95 per share — a jump of about 20% from the offer price.

By the end of that first day, SpaceX had become the sixth-largest publicly traded company in the United States by total value. The offering was so large and so sought after by investors that it easily met demand according to Reuters. The company confirmed the deal was complete on June 15, 2026, in an investor announcement.

What the Numbers Tell Us

When you multiply $135 by 555.6 million shares, you get approximately $75 billion. That is roughly equivalent to the GDP of several countries. Investors who bought shares at the original $135 price and held through the first day's close were up about $26 per share. That kind of jump on day one is unusual for such enormous offerings — underwriters typically price these deals so early trading stays relatively calm.

The stock trades on two exchanges: the Nasdaq Global Select Market and Nasdaq Texas. Nasdaq Texas is a newer exchange designed to operate under lighter regulatory rules, and SpaceX is now its biggest company.

What This Means for SpaceX

Until now, SpaceX paid for growth through government contracts with NASA and the Department of Defense, revenue from its Starlink satellite internet service, and private investors. Going public changes this. The company now has a fast, easy way to raise money for buying other businesses or paying employees with stock. The tradeoff is that SpaceX must now report its financial results to the public every three months, something the company has avoided until now.

For context, the offering was structured to appeal to investors in Europe as well as the United States — a sign of just how much interest there was.

SpaceX reached a company value that most firms take thirty years to reach in a single day. That happened because the company controls a growing share of the global satellite internet market through Starlink, which has thousands of satellites and millions of paying customers. SpaceX also dominates commercial space launches through rockets like Falcon 9 and Falcon Heavy.

The fact that investors absorbed a $75 billion offering without causing major price swings in the broader market suggests investors have substantial confidence in the company. It also means other large private companies in aerospace, artificial intelligence, and defense are now thinking seriously about going public themselves.

One thing worth watching: SpaceX, as a private company, could miss a quarterly profit target or experience a rocket failure without the stock price dropping. As a public company, it cannot. That kind of quarterly pressure is new for a firm that has built itself on long-term engineering bets and Elon Musk's willingness to tolerate setbacks. How the company adapts to that scrutiny over the next few years will be important.
